SIP Subscribers


The SIP Subscribers module provides the capability to register SIP End Points or trunks to the softswitch. The module scales to meet carrier requirements, with subscriber numbers ranging from a few hundred to thousands of subscribers (depending on the license selected).

OpenCA uses Advanced Number Analysis for routing all calls (independent of the call control protocol used) based on configured numbering plans and routing information. It supports thousands of call attempts and meets the "five 9s" of reliability.

The module provides SIP Subscribers with Class 5 features, including Call Hold, Call Forwarding service, Call Log. Class 5 functionalities also include Blind Transfer, Attended Transfer, Redirect on Busy, No Answer, Unregistered, and Unconditional. SIP Subscribers can also be added to groups to support Simultaneous Ring.
