Hi,
1.Two sites connected by leased line of 256Kbps, Hence I have 2600XM modular routers at each
site.
2.Cisco Callmanager 3.3(4) at each site.
3.IP phones cisco 7960 are connected to cat 3550 switches with trunking
4.There is intercluster trunking without gatekeeper between two cisco callmanagers.
Note: only one call manager at each site no redunadant callmangers.
5.IP phone to IP phone communication is working at each site locally.
6. When I call from a Ip phone at one site to Ip phone at other site its not working, this
is same case with either site.
7. I see in my gateway routers configuration a statements
Site 1:
=======
voice-card 1
!
no aaa new-model
ip subnet-zero
ip rcmd rsh-enable
ip rcmd remote-host remote-user 10.45.2.254 local-user enable

!

------------------------------------
8. what configuration should be in voice gateway routers at each site
when we use intercluster trunk.?
9. How does callmanger or gateway (router 2600) bind/register with
each other to make call routing.?
10. I have seen some technotes MGCP must be enabled in gateway to bind
to callmanger in FXS/FXO environment.. but my setup is intercluster
trunk without gatekeeper.
11. Do I need to use MGCP in case of H323, if so how do I use it.?
Note:- I dont have any gatekeeper mechanisim
....Please guide me how do I bring up this IP Phone communication.....
Regards,
Kishore
