CME cisco jabber voice


i have a CISCO2921/K9, i have cisco jabber voice configured and working on iphones,

but all the phones with a voice register pool 13 and above (13 or greater) are not working,

example :

     voice register pool  13

      registration-timer max 720 min 660

      id mac 1100.1100.1113

      session-transport tcp

      type CiscoMobile-iOS

      number 1 dn 13

      dtmf-relay rtp-nte

      username 691 password 691

works but anything above 13, like voice register pool 14 is not working.

any idea?

is this related to license problem, if yes how can i check how many voice pool licenses i have?

How does your config look? Look at the MAX-DN and the MAX-POOL values.

Please see example:

voice service voip
allow-connections sip to sip 

!--- Enable SIP to SIP calls.

registrar server expires max 1200 min 300 

!--- Enable Cisco IOS SIP registrar.

voice register global                     
 mode cme  

!--- Set Cisco IOS SIP registrar to CME mode.

 source-address port 5060 

!--- Set the source address for phone registration.

 max-dn 20 

!--- Set max extensions.

 max-pool 10 

!--- Set max phones.

 load 7970 SIP7 SIP70.8-2-1S 

!--- Specify phone loads for each phone type.

 load 3911 SIP3951.8-0-2-9 

!--- Specify phone loads for each phone type.

 authenticate register 

!--- Set authentication for phone registration.

 authenticate realm 
 tftp-path flash:  

!--- Specify path for tftp files.

 create profile 

!--- Create configuration files for all phones.

 dialplan-pattern 1 4085251... extension-length 3  

!--- Configure dial-plan pattern for the system.

Thank you for your reply,

The config is correct as many voice pool register are already working , just any voice pool register 14 or higher are not working, i have a TAC case opened with Cisco and they are checking it, once the case is closed i will updated here.

Thank you very much, well if TAC takes a while then surely it is something more than a license or n config.

Good luck and keep us posted please.

While preparing some debugs for the TAC team i found that the flash was full ,

so once i cleared some memory the extra pools worked.

Best regards
