controller T1 0/2/0

framing esf

linecode b8zs

pri-group timeslots 1-24

description Home_PBX

vlan internal allocation policy ascending


you are having this config already, First shut the controller


#controller T1 0/2/0

# shut

# no pri-group timeslots 1-24

# pri-group timeslot 1-24 service mgcp

# no shut

Correct Answer by Ayodeji Okanlawon about 3 years 7 months ago

That is because you have not configured your T1 controller for mgcp..


controller T1 0/2/0

pri-group timeslots 1-31 service mgcp


After you add this you should be able to add the bind command to the seria interface

You are missing the bind command on the serial interface..


interface Serial0/2/0:23
isdn bind-l3 ccm-manager


Add this...then do no mgcp, mgcp and test again

Thank you aokanlawon


I do not have this command, the only choice I get is q931, not ccm-manager...




2811(config)#interface Serial0/2/0:23
2811(config-if)#
2811(config-if)#isdn bind-l3 ?
  q931  Select IOS Q.931



2811(config-if)#isdn bind-l3 q931
2811(config-if)#isdn bind-l3 q931 ?
 

2811(config-if)#isdn bind-l3 q931

Thank you, Nadeem, I will go step by step, looks like the tutorial I have is incomplete...

  • Cisco Employee,

just made this sample config.



controller T1 0/0/2

pri-group timeslots 1-24 service mgcp


interface Serial0/0/0:23

isdn bind-l3 ccm-manager


ccm-manager config server 1.1.1.2 1.1.1.1 (frist sub and second pub ip) if you want to have redundancy.actually it depeneds which one is primary tftp and secondary one.


ccm-manager config

ccm-manager redundant-host 1.1.1.1

ccm-manager mgcp



mgcp

mgcp call-agent 1.1.1.2 service-type mgcp version 0.1


add Gateway on Call manager , make sure domain name sure be exactly the same on call manager. and do no mgcp and mgcp on gateway.

Still same problem, I have erased all that related to mgcp on my router, to start from scratch





2811(config)#controller T1 0/2/0

2811(config-controller)#pri-group timeslots 1-24 service mgcp

Cannot overwrite no serv type with one. Unconfigure existing configuration and reconfigure

2811(config-controller)#


Where is this error coming from ??

      



Here is what I want to try:

192.168.15.10  - pub

192.168.15.11 - sub




controller T1 0/2/0

pri-group timeslots 1-24 service mgcp


interface Serial0/0/0:23

isdn bind-l3 ccm-manager


ccm-manager config server 192.168.15.10 192.168.15.11


ccm-manager config

ccm-manager redundant-host 192.168.15.11

ccm-manager mgcp



mgcp

mgcp call-agent 192.168.15.10 service-type mgcp version 0.1
