PHONE IS TRYING TO REGISTER WITH ITSP AS AGAINST CME

Hello Guys, 

 

I got a SIP trunk from an ITSP but have been unable to register it. The problem is that the ITSP's SBC is rejecting my sip-ua registration request (from CME) because the requests coming from my CME are too many.  MY Cisco 7945 PHONES ARE ALSO SENDING REGISTRATION REQUESTS TO THE ITSP.  PLEASE HOW DO I STOP THIS? HELP!!!

So people who come after can find a solution. I already found a fix to this. 

This solved it for me;

Under telephony-service, the same line with max-dn, issue the "no-reg" command. Secondly, go to ephone-dn and also issue the "no-reg" command after "number xxxx no-reg". Example below;

 

telephony-service

max-dn 14 no-reg 

 

ephone-dn 1 dual-line
number 1001 no-reg

Is your CME a registrar server? What IPs does your phones have for TFTP servers?

Hello Rolando, 

1. My CME is the registrar server (at least all phones can call each other-intercom and dial-peers)

2. The TFTP server address is the address of the CME 172.16.xx.xx

If someone wants to do the same for SIP phones:

There is no no-reg in voice register global, you only configure it in the dn:
voice register dn 1
  number 1001
  no-reg


If that doesn't work...

In my case, the router still sent the registration of the phone to the provider after that. I unplugged the phone, no change. I removed the phone (pool and dn) config, no change. I removed the sip-ua for the connection to the provider but once I moved it back, the router did the same thing. In the end, only a reload could fix the problem.
