Why Choose Virocom?

Virocom’s SIP Trunking service is delivered from our carrier grade Voice Services Platform and resilient core Network which together eliminate the effects of jitter, latency and packet loss to provide high quality voice calls. Virocom’s advanced core network enables SIP-Trunking to be securely delivered over a multi-service connection thereby reducing Network and service deployment costs.

It is possible to add following features not available with ‘dial-tone only’ SIP Trunking as follows:
DDI Divert automatically diverts incoming calls to individual DDI (Direct Dial In) numbers to alternative destinations in the event of PBX or circuit failure or overflow.
Resilient SIP Channel provides two separate connections from the Voice Services Platform to two PBXs in the same cluster and distributes inbound calls to the PBXs using ‘round robin’ or ‘active / standby’ rules.

Call Queueing uses an Auto-Attendant function on the Voice Services Platform to automatically greet, queue and direct calls to an appropriate destination based on user input.
