SIP-T38G backup SIP server option? - Mupod - 07-25-2014 11:07 PM

We recently got some T38 phones and have been trying to find out how to use a second SIP server. We have some T20 phones that have this option in firmware, so it seems odd that the T38 wouldn't have it.

Here's what it looks like on the T20:

Is there a specific firmware I need in order to do this via the web interface on the T38?

T38 has poor firmware support. Yealink decided not to update the firmware versions beyond V70...

You can try the firmware posted in this other thread. It mentions the ability to add a second sip server to the T38G config file.

Please note that 38.70.1.xx firmware versions are test/custom releases, so use carefully. If it works out, you can give feedback so hopefully they will included it in the next stable version of the firmware.

Thanks a lot for the response. Could I trouble you for a link to Doesn't seem to be on their FTP server anymore.

It's just for testing purposes right now, we haven't deployed any phones yet so beta firmware is fine.
