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.
