CME 7.0

[cigalahgroup]

Hello,

      I have call manager express 7.0 installed on cisco 2851 router  IOS  c2800nm-adventerprisek9-mz.124-24.T.bin

every thing was working fine except when we changed the ip source address on the router the phones stopped registering it self.

If I see the from phone its taking the ip address, subnet mask, default gateway and tftp server.

if I run sh ephone commmand

It shows the phones are unregistered with out any ip address.

Hi,

please make sure to create new phone files after you made any changes:

conf t

telephony-service

create cnf

Also, make sure to have a dhcp server enabled to provide an ip-address to the phones:

ip dhcp excluded-address 192.168.100.1 192.168.100.50

!
ip dhcp pool VOICE_SCOPE

network 192.168.100.0 255.255.255.0
default-router 192.168.100.10
option 150 ip 192.168.100.10
domain-name MyDomain.com (change to yours)
dns-server 192.168.100.10

!

telephony-service

ip source-address 192.168.100.10 port 2000

Hope this helps,

Marc

I did ran create cnf but it didn't helped me .

Have you attempted a factory reset on a phone to see if that helps?

Can you provide "debug ephone register" and "debug tftp events"?

When you changed the source IP did you perform reset under telephony-service? Is the new IP address tied to a different interface on the router, is it routable?

No but I did hard reset my IP phones
