Okay big problem.

Inside phones - the ones connected at the main admin office, work like a charm. Plug them in and off they go.

Remote sites - nothing. No connect nothing.

Now the fun begins in trying to track things down.

My setup -

Main admin site -
192.168.0.0/24 - data
10.1.100.0/24 - voice

Remote sites - they start at 192.168.5.0/24 and go up in 5 increments. 192.168.10.0/24 etc.

Phones pick up an IP from the local routers giving them the IP from the 192.168.5.0 etc ranges. They will not attempt to grab an IP from the 10.1.100.0 subnet.

I have tried adding the ip helper-address of 10.1.100.1 but still nothing.

I have added static routes on the remote sites pointing them to the UC data connection.

I tried turning off the firewall at the remote sites to see if that was the issue, still no go.

I am taking a break from it now as I see if I can sort out why things are not doing what they are supposed to.
