The CommuniGate Pro Router processes every Signal address in the system.
- The Router uses Default or Custom records to detect telephony (PSTN) type addresses and to convert them to the standard E.164 form (+country_code area_code local_number) in the fictitious telnum domain name. For example, when a SIP phone user dials 011 44 3335555, the Server receives that address as sip:firstname.lastname@example.org URI, and the Router converts this address into +44333555@telnum address.
Usually all numeric addresses of the certain length are processed as PSTN numbers.
See the Router section to learn about the Router records used to detect telephony type addresses.
- The Router maps PSTN numbers to local or remote VoIP addresses, if possible.
The Router checks if an address (number) in the fictitious telnum domain is assigned to some local Account. If an Account is found, the Router routes the address to that Account.
For addresses not assigned to any local Account, the Router can use global and local ENUM services, as well as CommuniGate Pro Forwarders.
- The Router directs unmapped PSTN numbers either directly to a PSTN Gateway, or to a CommuniGate Pro Real-Time application designed to support external PSTN Gateways.
