Pushing voice data across different internet connection

[tsupport]

Hi,

We have had our phone system on VLAN 20 and IP address range of 10.0.20.0/24 for a while but we are moving to sip lines and are going to use a second internet connection just for the SIP trunks.

I have installed another network card in opnsense and given it 192.168.20.1/24 address and then our provider of the connection has a cisco router and have assigned 192.168.20.2 to their interface but I am having trouble pushing traffic for VLAN 20 across the new link, it appears that it wants to go out the existing (default) gateway.

I have setup on the 192.168.20.1 card the upstream Gateway as 192.168.20.2 and I can ping that address.

I have tried to put a rule on the VoiceVLAN to set the gateway to the 192.168.20.1 address but it when I ping address on the SIP providers network it tries to go through the default gateway and then says it can't find that address.

Any suggestions as to how to setup the routing for the connection?

Do you use siproxd?
