Hi,
I am NOT able to configure CISCO 7960 phones through SONICWALL NSA 4600 Firewall, I am getting UNPROVISIONED error.
I had sonicwall TZ 210 before and i never had any issue with configure, after upgrading firewall to NSA4600 i am have this issue. Please let me know the solution to fix this issue.
I already have following two ports open on nsa4600
Elastix RTP, Protocol: UDP(17) , Port Range : 10000 to 20000
RDP , Protocol: TCP(6) , Port Range : 3389 to 3389
My Environment:
Elastix 2.4.0
Asterisk 11.13
Thanks
Ram
