SER – SIP Express Router

Project Website: www.iptel.org/ser

For a different version see: OpenSER

On Nov 04, 2008, SIP Express Router (SER) and Kamailio (OpenSER) started the SIP Router Project

SIP Express Router (ser) is a high-performance, configurable, free SIP ( RFC3261 ) server . It can act as registrar, proxy or redirect server. SER features an application-server interface, presence support, SMS gateway, SIMPLE2Jabber gateway, Radius/syslog accounting and authorization, server status monitoring, FCP security, etc. Web-based user provisioning, serweb, available.

Its performance allows it to deal with operational burdens, such as broken network components, attacks, power-up reboots and rapidly growing user population.

SER’s configuration ability meets needs of a whole range of scenarios including small-office use, enterprise PBX replacements and carrier services.

Which version of SER is documented here?

This Wiki covers both the stable and the development branch of SER. When adding new commands, modules, and options, please also add a note on *when* this was added so that users may compare with their version date.

SER is an Open Source SIP server, licensed under the GPL
SER supports SIP over TCP and UDP according to RFC 3261
SER supports ENUM
SER supports several NAT support mechanisms
SER may interoperate with the jabber instant messaging architecture
