Hi to everyone.
We have a problem with SIP trunk between Cisco <-> Mitel.
If an user in cisco call a mitel user everythink in ok.
Sometime when mitel user call a Cisco user, mitel user can hear the cisco user, but cisco user cannot.
In mitel's logs, we have messages like this:
Port:14fd9f90 Could not Create a compatible MD. Event SMH_FSM_ANSWER State: SMH_FSM_WAITING_ANSWER
Anyone can help me?
Thank you
