We installed a new Ooma VOIP phone system and it works everywhere but our main office. We were told by Ooma that we needed to open the ports on the firewall to allow for the traffic.
UDP 53, UDP 123, UDP 514, UDP 1194,UDP 3386, UDP 3480, UDP 10000-30...
I dont know..I know I am getting an IP address internally; but no way to dial out.
.If I plug them in ANYWHERE outside of this office..they work great...I thought I could set the base station somewhere outside the firewall..but it wont work
it says "No Service on the Phones" but, I'm still getting an IP address.
I opened the ports using the attached screen..its how I did them for other services (Security, Alarm,,ect)
