setting mod_portaudio priority codec call out

[Tamer Higazi]

Hi people,

I am looking to configure the priority codec with mod_portaudio.

When I make an outbound call, pa uses PCMA as primary codec...
When I receive from the same person a call, G722 is used.

Any chance enforcing G722 as priority codec with PCMA as fallback by 
placing an outbound call?


Thank you
