CCME Internal extensions registering with external SIP trunk

Hi,

We have set up a CME with 8 internal SCCP extensions and 3 SIP extensions. After adding the SIP trunk to our provider I noticed that my extensions are trying to register with the provider. Even my MWI On/Off extension is trying to register with the trunk provider!

Provider not too happy about it.

Any idea what could I have missed in the configuration?

Debug:

6941 SCCP phone extension:

Check out your SIP UA config

Check out your SIP UA config section.  You have a SIP registrar configured which is causing your phones to attempt to register with a SIP Proxy/Registrar server.

But if I remove that line, wouldn't it make my sip trunk line stop working?

I did just that, but nothing

I did just that, but nothing changed. Also, I can't seem to add the no-reg parameter to my SIP phone definitions (voice register dn) anyway.

Hi.After you applied no-reg

Hi.

After you applied no-reg under voice register dn, did you try to go under voice register global and issue the command "create profile" and reset the phone?

 

Let us know

Hi, Actually, It is working

Hi,

 

Actually, It is working now (not sure if recreating the cnf files or the phone restart did the trick).

 

My only problem: SCCP phones are ok, but the SIP phones are still trying to register with the sip proxy. Can't use the no-reg parameter with those.

 

Any idea?
