I want to configure my Peplink Balance 210 properly for my SIP phone. I have a dual WAN setup with Comcast and AT&T Uverse in Florida. I need SIP traffic to stay on one WAN once communication begins.
I have a Nortel IP Phone 2004, model NTDU92. When I look at “Active Sessions”, I see these ports are being used:
source
5000
51012 rtp
51013
destination
7000
7001
28000 rtp
28001
51000 rtp
51001
What is the best way to configure my Peplink? I see I can setup an “Outbound Policy” and a “rule” set to “enforced” with the MAC address of the IP Phone. However, I don’t know how to enforce on inbound traffic. How would I do that?
Another way I see, is to go through the “Service Passthrough” section. However, under “SIP”, it looks like I can only set three custom ports. Would I enter source or destination ports, or both? In “Active Sessions”, I see 3 source ports and 6 outbound ports. Do I need to add only the source ports or do I need to add all 9 ports?
Also, do I need to set custom firewall rules?
Thanks in advance for help.
