How to route VoIP lines traffic specifically from WAN2 Port in RV042 Router?

[rkdatlapix]

Hi All,

We are using Cisco RV042 Dual WAN Router.

Wan1 is connected to ISP-A,  Wan2 is connected to ISP-B

We have are using WAN2 port as a standby.  I want to route all our VoIP lines( 4 lines) traffic through WAN2 Port i.e., through ISP-B.

Because the network latency with the ISP-B is very less.  How can I achieve this in RV042 ?

Thank you All,

Ram.

Does the Cisco RV042 support policy based routing?

Presumably your VOIP lines are just a SIP provider on the internet somewhere?

I didn't find any option related to the Policy Based Routing in my router. 

Yes... We give SIP server IP in the phone devices.

Thanks,

Ram.
