This unique solution for connecting the office PBX/PABX to VoIP, allows companies to immediately benefit from advanced PSTN, VoIP and Cellular (GSM, CDMA, 3G/UMTS) connectivity plus integrated LCR capability, all-in-one box.
Companies gain from expanded PBX capability and functionality, and can achieve major cost savings on call costs, as well as save the costs of an additional PBX E1/T1 card.
As a general guideline, we recommend installing our single E1/T1 PRI trunk PRI-VoIP Gateway in large organizations for creating an alternative, dedicated PRI trunk for VoIP access. We recommend implementing our 2 x PRI VoIP Gateway, with integrated LCR, for companies with a small scale PBX using a single PRI trunk.
Given the systems' flexibility, modularity and scalability, these advanced VoIP Gateway solutions can be pre-configured to meet precise customer requirements so companies can easily expand the cost-effective systems to meet their evolving telephony needs over time.
