RE: Multicast Formware for T38G
Hi

I'm experiencing the same issue with the new firmware. This is not necessarily a Yealink issue but I would appreciate any comments that you have.

We are using the T38G's connected to Asterisk. I've upgraded Asterisk a few weeks ago to try to resolve the issue prior to trying new firmware on the phones. We only have T38G's on the system and so I can't easily identify if this is a system or handset issue.

With the .172 firmware placing the resumed call back on hold and then immediately taking it off again always resolved the issue, however it has been reported today that this no longer reliably resolves the problem under the .221 firmware.

I am experiencing the same issue at two sites, so perhaps it's something that I have configured incorrectly. The problem occurs in less than 2% of calls. One site uses SIP trunks and the other ISDN30.

Any help or suggestions would be much appreciated.

Thanks

Steve
