Hi Everybody
I am new to this Cisco voice architecture and in need of basic config steps/guide to configure isr4331 as an voice gateway for connecting analog extensions in the FXS card.The Isr 4331 will be connected to CUCM 11.5.I am confused on the type of integration between CUCM to ISR 4331 ,whether to use SCCP or MGCP or SIP .Any quick guide in setting up the Voice gateway and CUCM configuration will be of great help.
