| [Other] Cisco 7960 "protocol application invalid"
I am trying to install a Cisco 7960 at my home office. I purchased the
unit new off ebay. The previous owner says he uploading the 7.5
firmware on the unit but never used it.
When I power on the unit, the top screen says, "universal application
loader" and the bottome says, "configuring vlan," then it goes to
"configuring IP," for about 5 minutes, then it goes to "protocol
application invalid." What does this mean? Can someone please help?
Thanks in advance for any advice or help. |

"Protocol Application Invalid" Error
This error message means that the application image cannot be loaded into flash memory or that the image does not exist in flash memory. This can happen for these reasons:
The ZIP package was not unzipped to the root TFTP directory.
Files were manually copied to the TFTP server (the ZIP package was not used).
The universal application loader was unable to load a new application image into flash memory (image authentication failure, nonexistent image, TFTP errors, and so forth).
OS79XX.TXT file must only contain the name of the file that you attempt to load, without the .bin extension. For example, if you attempt to load the SIP version 2.3 software, it must contain only the line P0S30203. If you try to load versions 3.0 and later, the file name must be in the format P0S3-xx-y-zz. For example, if you attempt to load the SIP version 7.4 software, it must contain the line P0S3-07-4-00.
The SIPDefault.cnf and SIPmac_address.cnf files are downloaded when a phone is reset. These files contain the image_version parameter that tells the phone which image it must run. Thus, if you attempt to load the SIP version 7.4 software, SIPDefault.cnf and SIPmac_address.cnf must contain image_version: P0S3-07-4-00.
Looks like your unit isn't properly loading software into flash memory. The problem is likely in the SIPDefault.cnf file, which tells your device where to look for network settings like a tftp server. Also, the 7.5 version firmware has some bugs in it like dropping registration and not re-registering without a hard boot. Version 7.4 doesn't seem to have these issues.
To change back to 7.4, you need a TFTP server to load the firmware. It can get complicated with this phone. You can read more about your phone at:

Thanks for the post. Would it be possible to use a TFTP server to read the phone to see what it is doing? Then I could read the settings and post them on the forum for others to view. Maybe someone will see the problem.
Where can I get a TFTP server? Is is complicated to use the TFTP server?
Also, could this be a problem with my router? I just got the router and I don't know if it is hooked up right? |

Try resetting the phone to factory default:
Complete these steps:
1. Go to the main Date/Time screen.
2. Press **# to unlock Network Configuration on the phone.
3. Press Settings.
4. The Network Configuration lock symbol should be unlocked. If it is not, exit to the main screen and press ** # again.
5. Press 3 on the keypad (or scroll down) for Network Configuration.
6. Press 33 on the keypad (or scroll down) for Erase Configuration.
7. Press softkey Yes.
8. Press softkey Save.
The phone should now be reset and stop looking for that image.

What VoIP service are you planning to use this phone with? Do you have your own CallManger?

| Thanks DTwilliams,
But the phone will not respond to any buttons, even **#. The buttons are completely locked and there is nothing on the screen other then "Universal application" at the top, a cisco logo in the center, and "configuring IP" at the bottom.
Is there a way to reset the phone manually without pressing any of the buttons? What happens if I reset the phone and do not have the files to load back onto it?
I plan on using Terravon as a voip provider and virtual pbx. They have been extremely helpful in explaining everything else to me. I do not plan on using call manager.
Do you have any other suggestions as to unlocking the phone without the buttons?
Thanks again for your help. |

| Not that I'm aware of. Quick CCO search found the following, which may be totally unrelated or of little help:
----------
CSCed84163: Loader may fail - Application Invalid
Symptom: When a phone is upgrade to release 6.0(1.0), from a 5.0 release, the upgrade may fail to complete. The Display will read "Application Invalid"
Conditions: This may occur if any of the following is true:
–There is no option 150 Set on the DHCP server on the native VLAN
–CDP on the Switch and Phone do not converge in a timely fashion.
Workaround: Insure that if a DHCP server is configured on the native VLAN, that it's option 150 information points to a known good call manager.
-----
CSCef75275: Symptom: Phones are intermittently stuck at Universal Application Loader. Phone Displays message "Configuring VLAN"
Condition: Phone load P0030700100. CDP used but no Voice VLAN (Aux VLAN) configured.
Workaround: Configure a Voice VLAN |

| DTwilliams,
This sounds like the problem. I just installed a router for the first time. The router is a Draytek 2900vg, with wireless lan, DHCP server, firewall and a bunch of other stuff that I'm not sure what it does. Anyways, this is the first time I set up a router and I didn't do any kind of setup to the DHCP server. I figured it would set up automatically.
So according to your last post, I need to input 150 into the DHCP server on the VLAN.
Can you tell me where would I input that information? |

| Why are you trying to avoid using TFTP?
Don't confuse a factory reset with fixing a bad image update. You have a bad image update. You will need a TFTP server to correct that.

While I have a working 7960, the correct (and legal) image I need, a properly working tftpd and a properly setup dhcpd server all of this does not make me an expert. But it is my opinion that you need all of the above to get that phone work properly. The proper way to get an image is through Cisco. Sorry, I won't give you a copy of the image. I can probably give you the rest with no problems as they are just the setup files you'll need. Mine are setup for P0S3-07-4-00 (SIP image, version 7.4).

I am trying to reset without using the TFTP server, because all of my keys are locked. The phone doesn't respond to anything, except for a reset of *6settings at the same time. All other buttons do not work. I was told that the phone is looking for the IP address on the sellers computer. It may also be looking for a TFTP server on the sellers computer, but since I can't get into settings to tell the phone to look for TFTP or IP address on my computer, then I need a way to reset the phone without the TFTP server.
ncherry
I have the complete 7.5 image and the 7.4 image. I am not looking for another image, but thanks for offering.
The only two options I can see, are to reset the phone to factory conditions or send the phone back to the seller and let him open it up with his TFTP server. I would prefer to fix the phone myself since I live overseas and shipping costs back and forth would probably end up costing more then the phone is worth.
I appreciate everyone's suggestions. Please continue to posts. |

| said by VoipNewbie1  : since I can't get into settings to tell the phone to look for TFTP or IP address on my computer, then I need a way to reset the phone without the TFTP server. The easy way would be to use a sniffer to see what address the phone is looking for the tftp server at. Then address yours to match.
OR
If you have a console cable, console into the phone and set those values.
Step 1 Connect to and access the console.
Step 2 At the console, enter the following commands.
a. set tftp-addr tftp_server_ip_address
where tftp_server_ip_address is the IP address of the TFTP server.
b. set def-rtr default_router_ip_address
where default_router_ip_address is the IP address of the default gateway router.
c. set dchp on or set dhcp off
depending on whether DCHP is used in your network.
Step 3 If you set DCHP off in Step 2, type the following commands. Otherwise, continue to Step 4.
a. set ip-addr phone_ip_address
where phone_ip_address is the IP address of the phone.
b. set subnet phone_subnet_mask
where phone_ip_address is the subnet mask of the phone.
Step 4 Type save.
Step 5 Exit the connection to the phone. |

| dtwilliams,
thanks again for your advice. I am going to try one of your options. As you can probably tell, I am not a techie so this is the first time I have ever heard of a sniffer or console cable.
I did a quick google and found a freeware program called Net Tools 4 »users.pandora.be/ahmadi/nettools.htm. This program has a TCP Packet Sniffer, File Dependency Sniffer, Advanced Packet Sniffer, and Messenger Packet Sniffer. Will one of these sniffers work?
I tried the TCP Packet Sniffer but received back around 1000 values which told me the IP header, Sport, IP Destination, and Protocol (most were TCP). What should I look for to find the value that is linked to the phone?
On the console cable, is this a cable that I can buy from a local electronics store and just hook it up to my router or my computer? Or do I need to order one from Cisco? Do I need any special software to use a console cable?
Thanks again for your help. |

I am having the same issue. Darn phone went smoothly from version 5 to version 6 of the SIP software and then it appeared to take version 7 but puked.
I have been watching this phone via Ethereal but no luck. Here is what it does:
- It broadcasts CDP/VTP immediately upon reboot.
- Then it performs a DHCP Request asking for the IP address that it last had.
- DHCP Server Acks the request
- Phone issues ARP for gateway IP Address
- Phone issies ARP for DNS server IP address
(neither ARP gets answered - ARP packet looks different than the ARP request issued for the gateway by the DHCP server which in turn do get answered - I'm still looking into this - Phone does a broadcast, the DHCP server seems to be directing the ARP to the getway - weird)
- Phone goes off into la la land and eventually ends up with the Protocol Application Invalid Error.
- Phone continues to renew its DHCP lease every 300 seconds - I changed this a couple of times in the DHCP server and it appears to pick it up every time so I think it is getting the DHCP information correctly yet it continues with the PAI error.
- The phone does not respond to any keypress other then *6settings - which just loops it back to PAI.
Other:
- TFTP Server is up and working correctly. I can TFTP files from it no problem. Also - I was watching on Ethereal when it went from v5 to v6 and saw all the TFTP requests, etc. - - Saw the same thing when it went to V7 but after it rebooted itself it hung.
I can get a serial cable from a friend but was wondering what setting all the IP info that DHCP is serving via the console is going to do. Cisco's web site says "troubleshooting" but only tells you how to set the IP info on the phone. That's not really troubleshooting. It looks like the phone is getting the info but then not actually doing anything with it? I'm guessing that somehow I botched the aplication load (duh) but there is nothing that I can find that says "hard reset to factory" or otherwise.
Any more help is greatly appreciated. |

Problem Solved.
After a lot of staring at ethereal traces I finally figured this out. As suspected it was a DHCP/TFTP Problem.
My DHCP server (ISC running on CentOS 4.2) was configured to hand out option code 150.... or so I thought. I finally noticed deep in the DHCP ACK that it was not being handed back to the phone. Surprisingly, simply commenting out the mis-configured 150 option statement and rebooting the phone cleared it all up. The phone defaulted the TFTP server to the DHCP server address (they happen to be the same on my network) and the phone started marching through the prescribed file hunt on the tftp server. It found the good v7-4 image, loaded it, reset itself, and was back in business.
The key to the DHCP config is that when defining option code 150 it takes 2 lines in dhcp.conf - one line to declare the option and one more to set it. For some reason, I didn't notice that.
In this example:
Linksys Gateway router at 192.168.1.1
Caching DNS Server inside the net at 192.168.1.5, external servers are xxx.xxx.xxx.xxx - change to suit your net.
TFTP server at 192.168.1.50
DHCP server at 192.168.1.50
I used the pool statements and adjusted the default and max lease times down to 60 seconds each to keep forcing the phone to get a new IP address but that ends up being unnecessary - whenever you reboot the phone even when getting the Protocol Application Invalid error it appears to do a DHCP Discover/Request sequence. The ARP strangeness in my previous post appears to be the phone doing some Gratuitous ARP.
Example dhcp.conf:
#begin dhcpd.conf
authoritative;
ddns-update-style interim;
ignore client-updates;
option voip-tftp-servers code 150 = ip-address;
option voip-tftp-servers 192.168.1.50;
subnet 192.168.1.0 netmask 255.255.255.0 {
#default gateway via the linksys
option routers 192.168.1.1;
option subnet-mask 255.255.255.0;
option nis-domain "your.org";
option domain-name "your.org";
option domain-name-servers 192.168.1.5,xxx.xxx.xxx.xxx,xxx.xxx.xxx.xxx;
option time-offset -18000; # Eastern Standard Time
option ntp-servers 192.168.1.5;
#range dynamic-bootp 192.168.1.100 192.168.1.254;
default-lease-time 43200;
max-lease-time 86400;
pool {
range 192.168.1.100 192.168.1.150;
deny all clients;
}
pool {
range 192.168.1.151 192.168.1.160;
#deny all clients;
}
}
#end dhcpd.conf
So, bottom line, you can un-brick the thing but you have to set up a TFTP Server for it to talk to and your DHCP server must hand out the correct options. If you're using a gateway device like the linksys make sure to turn off its DHCP server function so there is only one DHCP server on your network. Then of course you need to make sure your TFTP server has the correct SIPDefault.cnf and SIPMAC......cnf .sb2 and .loads, files etc there but that is a different topic. |

We had bought one of these Ciso phones and one PolyCom 501 phone. We could not (even with the assistance of Cisco's tech support) get the phone to load the latest firmware, much less even purchase it (the tech sent us the file). We decided it would not be worth the hassle to deal with these things, returned it and bought 20 more PolyCom phones.

Are you saying that option 150 needs to be set in the router or the TFTP server? I haven't set that option in either place. |

No, he had set it incorrectly which causes the phone to crash. If you have the capability to do so, by all means do it (it will make your life easier) but if you have a simple router the phone will boot and you need to set the TFTP server manually.

What I am saying is that option 150 must be properly declared AND set in the DHCP configuration. It must give the phone the ip address of the TFTP server that will give the phone the images and config files. That TFTP server must obviously be working for the phone to retrieve the required files.
Most simple routers such as a Linksys do not have a TFTP server buily in nor do they have the ability to give out the configuration required by this phone.
i am running a Linux box that acts as the DHCP server, the TFTP server, and the Asterisk server. |
