Prevent to add codecs in Re-INVITE sent for FAX
Hi All,
we have one transcoding policy having all compatible codecs with our switch and has been applied to access-realm for normal traffic. But when SBC is sending INVITE for fax calls with T.38 & PCMA, other codecs are also being injected as per transcoding policy. I just want to know if we can prevent transcoding policy to inject codecs in new call invite but not on Re-INVITE whic are sent for FAX negotiation.
I am using 9200 with TCU modules.
Regards,
