I'm going to put an SR520 in front of our UC540W in our test lab shortly, and wondered if anybody has done this and happens to know the proper ports to forward through the SR520 for SIP trunking and CCA access from the WAN? I assume that SIP trunking requires 5060, but do I need to include any other ports to make this work properly? I'm currently using NexVortex if that helps at all.
Secondly, I'd like to be able to access the UC500 and SR520 from the WAN for simple configuration changes and tweaks. Is it enough to just create a VPN tunnel with the SR520 if the UC540 has it's firewall shut down or do I need to create a VPN with the UC540 to access the UC540 and make changes on it's config?
How about remote softphone access? Is a VPN with the SR520 sufficient if the UC540 firewall is shut down? Do I point voice traffic through the SR520 to the UC520 at IP address 10.1.1.1?
Any help that might get me started on the right path would be much appreciated.
