Guys

Can someone help me to deploy the below :

PSTN çè CISCO ROUTER çèSIPCALL MANAGER

I want to match the inbound calls from call manager to cisco router based on source ip address.  i have already using answer-address however i need to match source ip address . Due to call forward issues in asterix call manager i need to match the inbound calls in cisco router based on source ip address and forward to specific pstn carrier.

I have read the topic voice source-group command but no idea how to use it. 
 
Your early response would be appreciated.
 
Thanks

Try something like this...


! ACL 1 matches IP of CallManager (10.0.0.100), deny all other IP's, which is permited by source group
access-list 1 permit 10.0.0.100
access-list 1 deny   any

! ACL 2 matches any IP which is rejected by source group
access-list 2 permit any

! Define voice source-groups to permit/reject calls
voice source-group voip-allow
  access-list 1

voice source-group voip-block
  access-list 2
  disconnect-cause call-reject

The result should be if call is sourced from ACL1, then its permitted. If call is sourced from any other IP location, it's rejected (call-reject).

Voice source-group is checked before matching incoming dial-peer.


Hope this helps!

You should be able to do this with 15.1(2)T.  There is a new dial-peer bind feature.

The command is under the dial-peer:

bind source-ip
