If a tellular is plugged to a UC320W, does the UC320W caters for autoswitching capabilities between preferred network where the UC320W will be able to choose the network to dial out depending on the prefix of the dialed out number?
Prefix based routing could be used to choose between different SIP providers and FXO ports. If you have one SIP provider for cellular calls and one SIP provider for Landline calls, then you could have different prefixes for each. FXO lines cannot be individually separated though.
Just for clarification, I know that you can assign digits to trunks, i.e. "9" for SIP A, and "8" for SIP B, however can the system route the calls depending on the number, i.e. if I type 0044.... for international could it pick SIP B, and dialing 0131... for a local call could it pick SIP A?
