I've got some dial plan rules that I've been pretty happy with in a single phone environment on my 2820Vn since I use three different SIP providers.

Now I want to use a business phone on phone 2, so I'd like it to use either a different set of rules or to only use a single, specified, SIP provider in order to keep the CLIDs different and for billing.

My first experiments have shown that phone 2 seems to follow the rules defined for phone 1, even though none of these providers are configured to actually ring phone 2, and I haven't seen an obvious way of disassociating it from these particular providers.

Has anyone done this, or does anyone know whether it can be done?

Thanks
