Forcing Opus codec on inbound calls

[slayerphil]

Hello

Can anyone point me in the right direction as to how I would force the Opus codec for inbound calls to an extension or even all extensions? I've got it working fine on outbound calls, but inbound is still using G711, I'm assuming there will need to be transcoding, but that's fine.

Thanks
Phil

Obviously the proxy sending you the inbound call will need to support/offer the Opus codec. The setting that controls what you will accept is inbound-codec-prefs on your external SIP profile.

Also look at inbound-codec-negotiation, by default it is set to "generous", but setting it to "greedy" will enforce your preferences.

You can also set the codec_string in your dial plan to specify a different codec set for certain circumstances. Here is a screenshot from one of my setups, not specifically inbound:
