Is it possible to configure the routers this way?

We have 2 group of computers connected to 2 different routers. My question is it possible to supply both internet and sip data to a group of computers and only sip data to the other group?

Yes, and quite common...

Have 2 VLANs, one for Voice and the other for Data and use firewall rules
SIP req both 5060 & 5061 and RTP media ports usually 10000-20000 on UDP

 

[prabha_friend]

Thanks Jason. We are on 5060 with just 100 ports. 10000 to 10099.

Are both routers the same make and model?
Also; is your SIPS server local or cloud based?

If you just want quick control use firewall rules or a better cleaner implementation, use VLAN's
