I have a mix of Yealink T23G and T27G.
I’m playing around with codecs. My SIP provider (flowroute) only supports ulaw and g729. So, I’m sticking with ulaw for outbound calls. But for internal calls, I should be able to use whatever codecs are supported by my phones, correct?
- Enable both ulaw and g.722 (the codec I’d like to test for internal calls). Prefer g.722 (i.e. move to the top of the list)
- Only allow ulaw out of the trunk
- Rebuild EPM configurations and reboot phones
Anything else I should be doing?
