Having an issue were five phones at a remote location went in and out of SRST mode. No hits on the WAN, and no issues with CUCM. Looks like a LAN issue but, phones are on different switches. Anyone experience this, any thoughts?
Actually, AT&T wouldn't need to disable SDN, you would simply apply the following command to you serial interface to accept the SDN.interface Serial1/0:23 isdn nsf-service sdn
