SRTP Settings

To enable SRTP for a Yealink phone go to Device->Phones->"Yealink phone"->Lines->Advanced-> and look for SRTP encryption enable .

Issue : this field lets you insert values such as 0,1,2 but you wouldn't know which value corresponds to what
Description says : Enable/Disable Voice Encryption(SRTP - which is not exactly correct because if you go over to the Yealink phone via its web UI you would have 3 options : Disabled/Optional/Compulsory - according to the Yealink plugin from admin portal these values correspond to 0,1,2 but the user wouldn't know that.

G.711 Codec Confusion

Under Device->Phones->"Yealink phone"->Line->Codecs there is no way of telling which codec is G711 U-law and which is A-law since both are named G711.

Workaround: Select both.
