[Freeswitch-users] Outbound codecs preference

[Juan Antonio Ibañez Santorum]

It doesn't worked as I thought. I'd like caller codecs priority has
preferente over provider codecs preference:

Now, doing inbound late negotiation and adding code you suggest:

IP phone offers:
   G729,PCMA (${ep_codec_string}= G729 at 8000h,PCMA at 8000h)

FS codecs prefs:
  global_codec_prefs=G729,G7221 at 32000h,G7221 at 16000h,G722,PCMU,PCMA,GSM"
  outbound_codec_prefs=G729,PCMU,PCMA,GSM

Provider offers:
   PCMU,PCMA,G729

Doing above config FS selects PCMA instead G729.
Disabling inboud-late-negotiation FS select G729 for A-leg and PCMU for
B-leg hanging up the call because there is no g729 licenses installed. It
could use G729 not dropping the call...
