Hi All,
Running into a strange issue with hopes of finding some answers here.....
We've recently migrated to SIP with our Mitel system and throughout the day, incoming and outgoing calls with just lose audio.
Example, a customer calls in, hears ringing, when our receptionist picks up, the caller just hears dead air. Receptionist see caller ID, phone rings, but just dead air and neither one of them can hear each other.
Now that strange part.....80% of the day, audio works fine..calls function normal.
Intermittently, we will lose audio.
It appears to maybe be a port issue on the firewall because when audio stops working, I temporarily open all UDP ports, and things go back to normal.
This is driving me insane because ports just don't close on their own and the intermittent audio drop outs occur at no specific times throughout the day.
Could audio be jumping ports? port 5060 are open both ways, which i am told handles audio.
