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
Thank you for your commnet. I really appreciate your answer.
Does it mean DS0 signaling require CCS ?
According to folloing URL, NM is available for both CCS and CAS.
Could you give me the refelence URL in detail which provide information regarding CCS required under this case?
I am really confused.
2811 does not require NM, use VWIC and PVDM2 directly.
It would be better if you engage a voice network engineer for the project, because if you have no experience it will take much time and errors for you to get it right.
