[SIPForum-discussion] Decline T.38 Fax calls before routing

[Murali Natesh]

Hello Rakesh,

Yes you can enable G.711 fallback for T.38. So the B party or not supported
party will send 488not acceptable. Then another offer will send to make fax
cal by G.711.Sip profile needs to be configured like this.

Regards,
Murali
