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
