Cisco Call Manager Express SIP Proxy registration - NON DID

mbroberson1

Level 3

Have a Call Manager Express and my SIP proxy provider is seeing failed registration attempts being from internal (non-DID) extensions. What could be the cause and fix for this. I assume it's not normal. My SIP proxy provider has said these failed attempts have blocked / firewall-ed off registration attempts from my IP.

In the below logs from the SIP proxy provider 1005 is an internal number with no DID associated. How can I prevent these from occurring?

Registration from '<sip:1005@did.voip.les.net>' failed for '76.97.XXX.XX:50251' - No matching peer found
