[Freeswitch-users] Freeswitch/freetdm<->Freeswitch PCMU always wins

[Kristian Kielhofner]

Check sip_codec_negotiation:

https://wiki.freeswitch.org/wiki/Variable_sip_codec_negotiation

Applies to inbound calls. Generous will allow FreeSWITCH to select the
most preferred compatible codec from the remote end. Greedy will force
the incoming profile to select the preferred compatible codec selected
locally. Scrooge is greedy plus more or less forcing a few extra
parameters (like ptime).

Scenario:
FS A (OPUS, G722, PCMU) -> FS B (PCMU, G722, GSM)

Generous set on FS B - G722 wins
Greedy set on FS B - PCMU wins

Scrooge should only be used in extreme circumstances.
