I have a customer with SIP trunks provided by Gamma.
The switch is a 500v2 at 6.1.5
Outgoing calls ok but incoming calls drop out after about 30 seconds.
Customer is using a Draytek Router, in Nat Mode.
Opened up ports 5060 -5080 TCP and UDP, 4000 - 60000 UDP, 3478 TCP/UDP going to Avaya IPO.
I am sure i have had this before in the dim distant past, but a senior moment does not allow me to remeber what the problem was.
Can anyone help please?
Thanks
