There is one thing which might help you, but since I am at home I don't remember the exact details. There is some codec parameter which should be set (on the phone) to 20mSec instead of 30mSec. I don't remember which one, but look on LinkSys documents on Freeswitch wiki - it has the same problem. Regards, __Yehavi: 2010/3/26 Dave Stevenson <stevendt@primrosebank.net>
Yehavi,
thanks a lot for the reply - not the answer that I wanted, but it does confirm my findings and tell me that there's no point in spending more time & effort on these phones.
Before I went for the ST2030, I checked out the FreeSWITCH Interop Wiki and saw that the ST2030 was reported as working with FreeSWITCH, unfortunately, the Wiki does not give any information on how good (or bad) the phones actually are. I also did some "Googling" and the phone appeared to get good reports (from Asterisk users), so I thought I was on safe ground. Obviously not though.
Oh well, I'll keep trying to find a decent VOIP phone with full SpeakerPhone functionality that does not have the footprint of the Cisco 794x.
regards Dave

We have one ST2030 and one other model of them which we bought for evaluation. We have the same problem as you describe, both with Freeswitch and Asterisk. That's why we have only one unit and not more...
from my experience, you get what you pay for.

Hi,
is anyone using Thomson ST2030 phones with FreeSwitch ?
I have a mixture of Cisco 7940 and the ST2030s. The voice quality of the Cisco phones seems fine, but the Thomson phones are pretty poor. I get quite a bit of noise (hiss) on the line and some breakup of the voice. The phones are all on a private LAN behind a router - all external calls are over the PSTN - no external IP calls are made (I don't use a VOIP provider).
I have loaded the latest Thomson SIP firmware (2.69). There are a couple of options on the phone that I've tried such as Silence Suppression, Acoustic Echo Cancellation and Packet Loss Compensation with no improvement. Most of the other options are beyond me I'm afraid, so I'd be really interested to hear from anyone who has good (or even acceptable !) results from the ST2030 - particularly if they could share their phone configuration
regards Dave
