Yealink T-4x provisioning : codecs and garbled sound

[GeorgSchwarz]

Hi!

In our autoprovisioning we just set the payload_type and the enable directive. This does not seem to change along the rtpmap of the "codec-slot" to the correct value.

So we solved the problem (after having checked with Yealink support and recieved the same answer as abobe) by setting the rtpmap for the respective codec to the to the values provided in the answer above:

Here our two sections for G722a and GSM:

account.1.codec.1.payload_type = PCMA
account.1.codec.1.rtpmap = 8
account.1.codec.1.enable = 1

account.1.codec.2.payload_type = GSM
account.1.codec.2.rtpmap = 3
account.1.codec.2.enable = 1

HTH,
