[Spce-user] Forcing Codec Negotiation

[Leopoldo Iglesia]

How can I force codec negotiation or registration?

Cause if I send a 488 when trying to fax T.38 there is no re invite at 
all. Te client side Offers All audio codecs and fax at a time and 488 is 
taken as if it all is unaceptable, so call
is never router.

Is there a way to force only PCMA registration, or only routing Audio 
codec info on invites?

THanks
