Variations in PBX Characteristics

The exact dialing strings needed in the Outbound and Inbound

Phonebooks of the MVP2410 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 MVP2410 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 MVP2410 can be completely transparent to

phone users within the company.
