SOLVED: T46 Codec Selection - Garbled Voice on Asterisk
Sorry, if I caused a misunderstanduing.

The problem was in fact our Autoprovisioning, and we did not see that some settings were still obtained from the server when we did a manual config after a firmware reset...

In our version that was initially built for v71 releases of the T2x-series whe had the codec selection like this (which works perfectly well for the T2x series)

account.1.codec.1.payload_type = PCMA
account.1.codec.2.payload_type = G722
account.1.codec.1.enable = 1
account.1.codec.2.enable = 1
account.1.codec.3.enable = 0

Obviously when I do that the RTPMap value does not change along with the allowed codecs.
I have now set the RTP-Map values according to your post, and my AutoProv-File now looks like this:

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

account.1.codec.3.enable = 0

And now things are working like a charm

Thanks for your excellent support,
