Last question tonight before I head to bed. After I get the SIP trunking issue figured out through a single WAN port on the SA520, I am hoping to put the device into load balancing mode and configure protocol bindings for SIP and RTP on the SA520 for the proper WAN port. Has anybody had success with this?
1. What services/ports did you configure? I can see the SIP-UDP and SIP-TCP that are already configured, but is it necessary to configure custom services for RTP or can I just use RTSP-TCP and RTSP-UDP for this purpose?
2. If I need to configure customer services, which ports does the UC520 use for RTP?
3. I understand what it means by "local gateway" but which network is the "source network" and which is the "destination network?" I assume that since this is an outgoing-type rule, that the "source network" would be the local LAN or the WAN IP of the UC520 and that the "destination network" would be left as "any" as our SIP trunk provider provides mostly signalling. Am I thinking of this in the correct manner?
Thanks in advance,
