VOIP installation for every business scenario

License No. TEL1/2560/15

Corecasys (NJ Network) provides VOIP installation for every scenario — linking branch PABX / IPPBX systems, building a Call Center, expanding inbound lines and calling internal extensions at no cost. Multiple providers can share one SIP trunk.

Link branch PABX

Connect two PABX sites so they can call each other free of charge over a VOIP trunk.

Call Center

Supports IVR auto-attendant and inbound routing by department — IPPBX performs like a traditional PABX.

International calling

Reach internal extensions from overseas and use global VOIP numbers free of charge.

Multiple providers

Connect multiple VOIP providers through a single external port and expand lines when PSTN capacity is full.

Why businesses still need PABX / VOIP

Even with Line, Skype and similar apps, business calling still relies on PABX — auto-attendant, departmental routing and direct reach to internal staff. Today IPPBX can match traditional PABX capability. See connection examples below.
