[OpenSIPS-Users] Call-id issue in Cancel message generated by tm

[John Nash]

I am not sure if its some bug or my mistake.

I am using topology hiding module (opensips 2.1 version) and I have noticed
that Call-id in "Cancel" message is different than "Invite" sent to
gateway.

Invite is sent to gateway and we get session progress but call is not
picked up, as per fr_timer opensips triggers cancel but call ID in cancel
is not same as sent in Invite
