I have a CCM 4.2 and a Unity 4.2 vm in my lab with a 2811 SRST router. I equipped my router with a dual port FXO, a dual port FXS card and a 9 port ethernet switch HWIC with POE. We have a centralized build in our live environment and our remote sites use an MPLS for call signaling and then the calls go over the local PSTN. We want to set up a test environment that mimics the live environment using an AdTran to fake the PRI connections at the sites. Can I do this without a VWIC card in the 2811 router?
Any feedback would be greatly appreciated.
