Which IP phones have best voice quality, preferably under $150
Hi all,
I have to buy some IP phones. Previously I have used Grandstream GXP-2000,
Budgetone 101 and Linksys SPA-841. I always had problems with sound quality
with all of them, and I was always of the opinion that it were the phones
which were not good. In GXP-2000 deployment of about 50 phones, some work
good, some have sound problems like words missing, clicking sounds when
talking, and some

How to do Automatic Daylight Saving on Grandstream GXP-2000
Hi,
I'd set the daylight saving option to yes on all the GXP-2000 phones, but
apparantly it doesn't move it an hour back on last sunday of October. So now
I am stuck will all the phones showing the wrong time. Isn't there an option
so that it'll automatically update daylight savings?
Thanks

Cepstral voice quality not good
Hello list,
I have been using Cepstral's 8KHz voices for my text-to-speech service for
some time now, and have been noticing that the voice quality is really poor,
doesn't matter what phrase I give it to convert. None of the other 8KHz
voices I have ever used were this bad. It doesn't seem good enough system to
be used in a commercial system. Is there any better quality text-to-voice

Recently I've noticed on a customer's GXP-2000 phone that it loses its IP
addresse for a few seconds, audio goes blank obviously, and after about
30-60 seconds get the same IP addresse back and resumes the call. This shows
that call was not dropped but phone lost connection with the server, whereas
the caller on the other end was still talking. This is just unacceptable as

Suggestions for web based soft phones
For a while now I've been looking for a good web based soft phone solution,
but so far no luck. A few solutions which I've tried, both Java based and
Flash based, either don't work, or had bad sound quality. I need something
which I could put on my productions server for my clients.
Seems like good web based solutions are all paid ones, nobody is giving it
for free. Any ideas,

Timecondition fallthrough on 2nd GSM Modem, First modem and ZAP's are all fine
Hello,
we have an asterisk (1.4.21.2) with ZAP and mISDN channels, the mISDN are 2 incoming GSM Modems, each with 2 simcards.
No, the mISDN line one and two are fine, but when I get a call on line 3 something with the time is wrong. Timeconditions fall through to off-hours even if the time of the call is clearly inside business hours, here a log excerpt:

Why only one out of many IP Phones re-registering every one minute
On one of my servers I have many IP phones connected, locally and remotely,
and all of them have register expiry set for 1 min. But on Asterisk CLI I
see only one of them, extension 502, re-registering every single minute.
None of the others re-register or info doesn't come on the CLI screen. This
one phone is remotely connected. What is the reason for this. And also
everytime it re-register,

Friday VUC 12 Noon ET with Kristian Kielhofner: Identifying Asterisk Quality Issues
Happy New Year in advance by a few ticks for the northern hemisphere.
Here's the first topic and guest for 2009:
In any voice path there are several potential sources of quality

the potential for

Which IP Phones will work with non-Asterisk PBX systems too?
Hi everybody,
One of my customers wants to buy IP Phones and Asterisk solution, but his
requirement is if he'll not be happy with Asterisk, his phones should be
able to work with other IP PBX systems as well, so that he doesn't have to
buy new phones again. After all IP Phones is the main investment. He'll most
probably go with Nortel IP PBX system if he'll be not satisfied with

How to use SIP hints and BLF for realtime extensions on Aastra phones?
Hi,
I need to make use of BLF feature on Aastra 6757i phones but its an Asterisk
1.4 using realtime architecture. Extensions are defined in realtime database
and dial plan is in AEL. I am able to correctly setup hints in the dialplan,
but they don't work. Did some research and found out that hints don't work

Why Aastra uses 48V whereas other IP Phones use much less, i.e. 5-12V
Hi,
Why Aastra phones use more electricity, i.e. 48VDC whereas other phones use
much less, e.g. Grandstream and Linksys both use only 5VDC. I first thought
it was because of PoE, but the ones with 5VDC also run fine on PoE. What is
the difference in power consumption then?

How to disable day light saving on Snom 360 phones?
Greetings,
Sounds like a simple thing to do, but I was not able to do it on these
particular phones. Snom wiki was not helpful. My client wants to keep his
phones pointed to UTC time, no DST, no change in timezone, i.e. to stay at 0
hours difference.
The phones are provisioned from a tftp server.
If I remove 'dst' value from the provisioning file, on bootup phones force
