We are trying to setup SRST-CME. We are having issues with dial-peers and preference.
We have normal dial-peers that send calls to CallManager where it chops off the first digit for our 3 digit extensions. When I build the CME-SRST config on the router, the ephone-dns are taking a higher preference than the dial-peer to send the calls to CallManager. So, even when the CallManager is live, the DIDs are going to the CME and getting fast busys since no phones are registered.
I created secondary extensions on the phones with their 4 digit DIDs and giving those secondary extensions a preferrnce of 5. I then created a dial peer with a $ at the end and preference of 1 pointing to CallManager. So when the CallMangager is up, it uses the preference 1 dial-peer. When it is down, the router uses the "virtual" CME dial-peer.
