Hi, Please help me.
I have to implement VoIP using MPLS like following.
I need to configure Cisco2811 and need to ask PBX-A vendor to add E1 card and configuration to PBX-A.
Should I pay attention to CCS ( or CAS ) between PBX-A and Cisco2811 ?
Does It has nothing to do with this case ?
controller E1 1/0
clock source line
ds0-group 1 timeslots 1-8 type e&m-wink-start
