Two Internet connections to UC520. 1 for data, second for voice. Voice using SIP trunking via the Internet. Is there a way to force the SIP and RTP traffic out the second connection or to source if from the interface connected to the second connection?
A couple specific IP routes are somewhat effective to establish calls, but the media streams are all over the place as far as IP's are concerned, so static routes are out.
I've tried local policy routing, but haven't been able to figure out a combination of ACLs, etc. that match the traffic I need to force.
