no voice

I have three call managers. Pub, Sub1, Sub2.

When I register phone A to sub1- gets an ip address 10.3.10.10

When I register phone B to sub 2- get an ip address 10.220.1.13

These two phones can call each other but no voice can be heard between them.

If I register Phone B to sub 1 it keeps the same ip address (10.220.1.13) and two way voice is ok.

The same voice path is used no matter which cm the phones register to, so ip network must be ok.

Any suggestions of where to look?

Re: no voice

Which callmanager you register to should not make any difference to the IP address.

It sounds like you have some sort of DHCP conflict, check the ip helper commands for each vlan to start with.

What you need to get sorted first is that registering a phone to a differenct Callmanager should NOT change the ip address.

cheers
