I have an isr2821 with EVM (8fxs and 6fxo) and vwic2-2mft-e1.
In my original design I though use MGCP protocol for the e1 and fxo's (with cucm6)
The customer told me the telco only offers e1 cas-r2 for the PSTN. Now I have several questions for you:
1st. e1-cas r2 force to use h.323 protocol.
2nd The recommendations for fxo is use mgcp.
3rd The recommendations for fxs is use sccp.
4th I don't want complicate the config with dial peers.
Its possible to use simultaneously the three protocols in the same 2821 router?.
