I have two separate network setup.

192.168.10.x on CME Data

10.1.1.X on CME Voice on CME WAN FE0/0

CME have a SIP trunk to VOIP provider.

SCCP phone all registered on 10.1.1.x network.

And I managed to get SIP client on 172.16.1.X registered with the CME and able to make call to SCCP phone at 10.1.1.x and also outgoing call via SIP trunk.

However, the issue is the SCCP phone on 10.1.1.x network can't call to the SIP client on 172.16.1.X network. When call to SIP client, it only silent and does does not get any response.

Have anyone testing this type of setup before?
