T26P peer to peer configuration problem

[Wilson_Yealink]

Hi CarlosVela,
I have tested it in my side, it does work well.
So please try below steps:
1. Reset the phone to factory
2. upgrade the firmware to the latest version. The latest firmware version of T26 is 6.72.0.75. Because I test it in this version. So gennerally it should also work in your side. You can get it from below link.
>>6.72.0.75<<

3. If after upgrdaing the issue still exist, please change the codec order of T26 and try again.
Access to web GUI->Account->codec tab, you can change it in the right list field.

thanks
