I just installed CUCM 7.1.3 in my test lab and also have got CCME 7 on cisco 2811(IOS version 12.4(24(T)).
On CUCM 7 I have got range of number 6000-7000
registered phone 6000
ON CCME I have got 2000-3000
registered phone 2000
normaly in order to call to another ccme from ccme I used:
dial-peer voice 101 voip
description ## ##
session protocol sipv2
session target ipv4:10.110.1.1
but If I do the same with the CUCM I am getting a message unknown number(after calling 6000).
I also set up set trunk from CUCM to ccme and added route pattern for extention 2000 it should go to ccme,
but when I am getting bussy signal.
I have been checking this link __http://theucguy.wordpress.com/2009/02/20/how-to-configure-a-sip-trunk-between-cisco-call-manager-5x-or-6x-or-7x-and-ocs-2007-r1-or-r2/ and dont think it should be much different from above.
Can you help me with setting it up and get it working please?
