Issues with phone registration

Hi all,

I have a big problem and so far I can't any solution. I was hoping that someone here can help me.

We currently have C2921 running CUCME 8.6. We have 3 phones: 1 x 7945 and 2 x 9971. Our phone system is setup to work using SIP. When phones are connected to network they can get DHCP without any problems but once they are registering they are going through registration multiple times (from5 mins to even couple hours). Every time it's finding correct files but it can't register. When  I debug TFTP I get:

Then it's waiting (with registering message displayed on phone screen) and after couple minutes registration failing and it's going through this again. After couple fails it's always registering but it takes sometimes couple hours.

Re: Issues with phone registration

Put the max-ephone under telephony service:

Router(config-telephony)# max-ephones "Number of the Phones"

Re: Issues with phone registration

1. telephony-services is not relevant for SIP protocol

2. I've got it already as I have SCCP setup as well.

Hi Pawel,

Do you have the below commands in your CME.

voice service voip

  allow-connections sip to sip


  registrar server

Please check this out.

Yes, all 3 lines are there. I also have SIP trunk already setup and it's working fine.

Were those phones registered to a CUCM cluster running version 8.0 or above prior you attempting CME registration?

Hi Ivan,

It looks like phones were trying to register with SIP trunk provider instead of local SIP server. I recreated config and it was working correctly.
