[Freeswitch-users] sip Allow headers differents between 2 legs

Hi all, FS receives on its A-leg this SIP Allow header: Allow: OPTIONS, PUBLISH, INVITE, ACK, BYE, CANCEL But when it sends INVITE to B-leg, it adds others parameters: Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, INFO, UPDATE, REGISTER, REFER, NOTIFY I saw that it's not possible to modify Allow header with FS. Is there a way to copy exactly the same Allow header between 2 legs ? thanks in advance ++
