Hi Community,

We are testing outbound B2B calls and found out this SIP URI addresses for testing:

loopback@rtp.ciscotac.net 
loopback2@cisco.com

The network admin needs to know the specific IP addresses that need to allow on the firewall to reach these addresses because any IP address destination are not allowed.

Please help.
