[Equipment] Yet another DECT thread

My cordless phones are dieing (or dead). Being heavy VoIP users, I'm thinking I might just get some DECT SIP phones.
I haven't been impressed at all with what I've seen thus far. Does anyone have any suggestions? Looking for "real world" users.
Money is an object as well. Would like to keep it under $200 for 2 handsets.

What have you seen? We're pretty happy with the current crop of Gigasets. The C610IP goes for $150 with two handsets, and the handsets themselves are decent.

The older A580IP is soon to be discontinued. It's handsets were too plain/simple for may people, but they were cheap.

There's a number to choose from; Panasonic, Gigaset, snom, NEC, Aastra.

We've come a long way from the Feb 2008 when the snom m3 was the only consumer SIP/DECT system sold in the US.

I may try the newer Gigaset out. Have they cleared up many of the glitches with firmware releases?

I've been using the KX-TGP550T04 Panasonic with 3 handsets for almost 3 years now and have been quite happy with it. On average, I log about 7k minutes a month it. The only thing I've ever done with it is change out the batteries (AA rechargeable). It's not fancy, with web browser or any extras, it's just a work horse.

I tried that device early in it's life. It had issues that stopped me dead. Did they ever get beyond purely numeric entry for SIP accounts? Did they ever allow dialing by SIP URI?

It was nice looking hardware, but the firmware was slow to evolve.

Mine is connected to my Asterisk server - so I'm not positive about SIP account entry. Perhaps someone else can answer that.

As for SIP URI's, they are in my speed dial plan on the server.

I've been using the C610A IP for about a year and am very happy with it. I just bought a second handset and it works very well. If you are a heavy voip user, just be sure to charge the handset every night!

A word of advice about the Gigaset range, it can be important to select a model that's relatively new. For example, they initially launched the A580IP & S675IP in the US, offering the C59H and SL78H handsets as optional additions.

Both the A580IP and S7675IP systems are now depricated and there will be no further development of the software on those platforms. The hardware capabilities of the platforms are very constrained in order to keep manufacturing costs low. That means that the development life cycle on a particular model is not very long, two years seems to be about the average.

Similarly, if you plan to mix and match handsets against a common base you're better offto get the newest handsets available. You can pair the C59H to the C610IP, but I'm not certain that they will take the newest firmware.

The C610IP is the new baseline in the US. It was introduced last year so it's currently in the middle of it's life cycle.

All of this really only matters if you hope for some new feature in the device. Each firmware release builds upon the last, even across models. Thus the current firmware for the C610 can be considered a superset of all that's gone before.

I have a Gigaset C610P with four additional handsets and have been exception pleased with the build and sound quality as well as the features set.

Just today Grandstream introduced a new SIP/DECT system. Here's the press release.

»www.grandstream.com/news/dp715_710_pr.pdf

I'm not the biggest fan of the company, but I know some people who really like their price/performance mix. Supports 5 handsets and 4 concurrent calls. At $85 for the basic system and $49 for additional handsets they could be competitive.

No support for HDVoice or dialing by SIP URIs. That's a deal-breaker for me.

I like Grandstream's current offerings. I used to be turned off by their stuff. I've actually got a Grandstream on my desk right now as my "daily user".

That is very surprising, not having the HD Voice G722. Some of their existing desktop IP phones do have it.

But it does have some nice features:

When multiple handsets share the same SIP account, Hunting Group option may flexibly support:

Linear Mode, all phones ring sequentially in the predestinated order

Parallel Mode, all phones ring concurrently and after one phone answers,the remaining available phones can place new calls

Shared Line Mode, all phones ring concurrently and always share the same line similar to analog phones

Does the RTP stream get generated at the handset, or at the base? If at the base then G722 wouldn't be supported because, iirc, DECT compresses voice data down to G726.

HD voice is a non-issue for me. The only time it works is on internal calls.
My provider doesn't support G722. 90% of my customers are calling from cell phones or POTS any way.

Well, that's a good point....

....although the Panasonic KX-TGP500 which has ONLY cordless handsets still supports G722, so it must be of some use anyway. That is, at least the base compresses voice data as HD for the journey to the outer world.

Found the Grandstream manual here: »www.grandstream.com/products/dp_···lish.pdf

What was disappointing is that only allows for 2 SIP providers. It is really fuzzy if a handset could use either SIP1 or SIP2. Handset setup is very confusing. I'd have to physically have one to test with, so we'll rely on your report...

The link that mgraves shared says differently...

quote:
The DP715, which includes the DECT handset and the VoIP base station with integrated charger, supports up to 5 distinct SIP accounts...

In fact, the link you provided says the same...

quote:
Multiple SIP accounts per base station
Up to five (5) distinct SIP accounts per system; Independent SIP account per handset; Multiple handsets per SIP account

Yeah, maybe I didn't recall correctly. It looks like at least the newer standard may support G711 and G722.
