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
