An IP Phone registered on SRST mode

Hi All,

I only have 1 of 15 phones registered on SRST mode, my question is how can I force to register again with the CUCM, just plug-out and plug-in or any command on the Voice Gateway...

Thanks in advance

Regards

Andres

Andres,

One way to force the registration is to reset the phone(s):

router#conf t

router(config)#call-manager-fallback

router(config-cm-fallback)#reset all

Hope this helps.

If the reset doesn't fix your problem the issue could be DNS.

Browse to the phone by putting its IP Address in a web browser.

Look in the configuration settings for the Call Manager Field. Could be named something like Unified CM 1 or Unified CM Primary etc...

If there is a host name for CUCM in this field then the phone will use DNS to resolve that host name.

If the lookup fails the phone will move on to Unified CM 2 and then its SRST Router field which is usually an IP Address.

 

Fix the DNS problem and your phone should register to CUCM.
