Have you tried <param name="inbound-codec-negotiation" value="generous"/>

From http://wiki.freeswitch.org/wiki/Sofia_Configuration_Files#inbound-codec-negotiation

inbound-codec-negotiation

set to 'greedy' if you want your codec list to take precedence

 <param name="inbound-codec-negotiation" value="generous"/>

if 'greedy' doesn't work for you, try 'scrooge' which has been known to fix misreported ptime issues with DID providers such as CallCentric.

A rule of thumb is:

• 'generous' permits the remote codec list have precedence and 'win' the codec negotiation and selection process
• 'greedy' forces a win by the local FreeSWITCH preference list
• 'scrooge' takes 'greedy' a step further, so that the FreeSWITCH wins even when the far side lies about capabilities during the negotiation process

sip_codec_negotiation is a channel variable version of this setting

inbound-late-negotiation

Uncomment to let calls hit the dialplan *before* you decide if the codec is OK.

 <param name="inbound-late-negotiation" value="true"/>
