Hi to all!.
I have to configure a Cisco ISR 4321 Voice Gateway as SRST for a CUCM in a central Site.
This Router will handle a E1 and will be connected to Central PUB & SUB CUCM with SIP trunk.
Could you guide me to me how to configure this feature and all tips regarding that configuration please?
I configured Cisco Voice gateway between Asterisk PBX, but not yet with CUCM.
Thanks in advance.
