Codec Per Domain/Extension

[Len]

How can I set (force) specific codec per domain or extension/s instead of entire system ? Seems codecs are set across the entire profile. Do I need to set it in the dialplan ? Can someone please show me the syntex.
I have some endpoints at low bandwidth locations and I would like to set the codec preference for those as 1-opus 2-G729 etc.
Thank you

set the codec on the phones, that enable you to limit as tpo where the phones are. you could also set it in the phones provision profile under settings if you know the setting on teh phone.

You are better off setting them on the endpoint if possible. The default codec negotiation is 'generous' which allows the phone to override the preference of the PBX. If doing it at the PBX end you would also need to change codec negotiation to 'greedy'.
