Re: How to do an SPA-3000 setup like mine...
said by kreil  : What do you mean with the "line" jack of the SPA3000? It would have an FXS port going to the analogue phone, an FXO port to go to the (analogue) phone company, and an Ethernet port. The SPA-3000 has two RJ11 telco jacks labeled "Phone" and "Line" (in addition to the RJ45 jack for the ethernet).
The "Phone" jack is really an FXS port, and the "Line" jack is really an FXO port. I think they just labeled them "Phone" and "Line" (and also used those terms in their web interface and their documentation), to make them easier for non-telco people to understand. Since Sipura refers to them as "Phone" and "Line", I continued those labels, instead of calling them FXS/FXO, to avoid confusing people who might wonder which jack is which.
It makes sense in a way, as people are used to hooking up a "phone" to a jack labeled "Phone". Likewise, it makes sense to "a normal user" to hook up a "phone line" to a jack labeled "Line". But how many people that aren't already telco experts would know what an FXS or an FXO is? |

| Sure, you're perfectly right! I was just trying to clarify which ports you were referring to (I don't have an SPA3000 in front of me - yet?)
Say, I have just been pointed by colleagues to a non-Sipura device called Fritz!Box Fon by the German company AVM, which apparently is similar to the SPA3000 in features just better documented. Moreover, it is apparenlty running Linux inside the small quiet box (bit bigger than the SPAs), and there are inofficial firmware patches that activate a telnetd and let you login to it from the outside. Sounds like haven for finding tricks to do more with it than intended. Then again, I've never seen it mentioned on these forums. Have you heard anything about it ever?
Also, while there are versions of it that have a DSL modem built in and which do QoD traffic shaping, they don't have that for cable users (like myself).
So I'm back to a situation where I might just as well get an SPA1001 for the little I need.
My earlier question regarding this may have drowned in all the other problems I've had but: Do you have any experiences with how the Sipura SPAs live behind a normal router that is not especially designed to prioritize voice traffic in an upload heavy environment?
With best regardd,
David. |

In my limited experience, Sipura adapters seem to perform about as well as any ATA would when behind a non-QOS router.
In particular, if you are in a tight bandwidth situation (heavy downloading on a PC, for example), you will likely notice the sound quality drop. But if you have sufficient bandwidth (I'm on a 1.5meg/256k DSL line, for example), you will likely notice no sound quality issues UNLESS you are actively using that bandwidth at the time. I rarely have sound quality issues with my SPA-3000, and I have not (yet) put it behind a QOS router. |

Austria | Thanks, DracoFelis!
That's very useful to know. Off to ponder what to do an on the hardware side...
Best regards,

Aaaargh!
sipgate.co.uk support:
"We do not currently support call forwarding and reinvite.
There are no methods to forward your number to another Sipgate number."
Thoroughly disentchanted, I am. 
That only leaves either having two phones sitting side by side, a hardware gadget to combine two phonelines, or an SPA-1001.
Or the Fritz!Box. I'm increasingly wondering...
