Has anyone else encountered an issue with outbound dialing 800 numbers when enabling caller ID with name? When dialing, we receive a fast busy. Below is the dial-peer and serial interface config. As soon as I removed this from the interface: isdn supp-service name calling, 800 numbers can be dialed.
dial-peer voice 138 pots
preference 1
destination-pattern 918[0678][0678].......
