we are currently moving to a new internet and voice provider. we are currently running the old and new side by side. our new service will have new routers Sonicwall TZ300s at each location. our corperate office has our PRI box and our mitel 5000 box. Each location is on its own subnet, the connections are up and routes are in place on the new system and everything works. Both sides can ping eachother in tests and the data and remote desktop sessions work great in tests. we have no VLANs, our phones are on the same subnet at each respected location as the data.

i did a test this last weekend to switch everything over to the new ISP. (Phone numbers have not been ported so i understand calling in wouldnt work, strictly a network test) at our cooperate office, data and phones worked great. phones came right back up to the mitel box no issues. our remote site the data came up fine, but the phones were stuck "Contacting server" i am able to ping the mitel box from the remote site.
what could be causing only the IP phones to not route across my network to the Mitel Box. is this a Sonicwall Issue? or a Mitel issue?
