The 2.1 OpenSIPS version brought a radical change in how the SIP traffic is handled - a … Continue reading Advanced SIP scenarios with Event-based-Routing

The updated module will be compatible with all MongoDB 2.4+ servers. The main reasons … Continue reading How to Use the Enhanced MongoDB Module in OpenSIPS 2.3
SIP setups where OpenSIPS acts as a front-end for a farm of class 5 servers are becoming increasingly popular. Such architectures combine the best of both worlds: robust and optimized handling of SIP signaling with feature-rich class 5 softswitches. This way of integrating open-source projects has lead to a unique opportunity for our team, along with the FreeSWITCH team, to … Continue reading FreeSWITCH-driven routing in OpenSIPS 2.3

This is one of the most common issues we get in SIP and one … Continue reading Troubleshooting missing ACK in SIP

I'm glad the books received good reviews at Amazon and … Continue reading Learning OpenSIPS

SIP-I considerations The SS7 interconnections are always painful. Both as cost and technical difficulty/complexity. So, as a more accessible alternative, the carriers started to offer SIP interconnection via SIP-I (SIP Infrastructure). SIP-I or SIP Infrastructure (define by ITU) is very similar to SIP-T or SIP for Telephones (defined by IEFT). SIP-I is very powerful when … Continue reading SIP-I and SIP with OpenSIPS 2.3
SIP without billing is like a dinner without a good wine. While OpenSIPS does a great job for SIP, it often needs a billing partner to work with. CGRateS is an open-source rating engine used for carrier-grade, multi-tenant, real-time billing. It is able to do both postpaid and prepaid rating for multiple concurrent sessions with different balance units (eg: Monetary, … Continue reading Real-time billing using OpenSIPS 2.3 and CGRateS
