Variations in PBX Characteristics
The exact dialing strings needed in the Outbound and Inbound Phonebooks of
the MVP2400/2410 will depend on the capabilities of the PBX. Some PBXs
require trunk access codes (like an “8” or “9” to access an outside line or to
access the VOIP network). Other PBXs can automatically distinguish between
intra-PBX calls, PSTN calls, and VOIP calls.
Some PBX units can also insert digits automatically when they receive certain
dialing strings from a phone station. For example, a PBX may be
programmable to insert automatically the three-digit VOIP identifier strings
into calls to be directed to analog VOIPs.
The MVP2400/2410 offers complete flexibility for inter-operation with PBX
units so that a coherent dialing scheme can be established to connect a
company’s multiple sites together in a way that is convenient and intuitive for
phone users. When working together with modern PBX units, the presence of
the MVP2400/2410 can be completely transparent to phone users within the
company.
