SIP Express Router

SER - SIP Express Router
http://developer.berlios.de/projects/ser/

Original Website: http://www.iptel.org/ser/
Website of the OpenSER fork: http://openser.org/
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
  • SER supports multiple user DNS domains in parallell
  • SER is extensible with modules for various additional functions
  • SER supports DNS SRV lookups

SER supports SIP connections with more features and more scalability than Asterisk. Normally, SER would be used in conjunction with Asterisk when a SIP phone needed to connect to the PSTN.

SER modules

If "experimental" this applies to the 0.8.11 release.

Explication please

by David Goldstein on Friday 11 of November, 2005 [02:28:36 UTC]
Hi,

Can anyone expand on this comment (SER supports SIP connections with more features and more scalability than Asterisk. Normally, SER would be used in conjunction with Asterisk when a SIP phone needed to connect to the PSTN) so that a first-time Asterisk novice can understand the logic of how SER and Asterisk work together to connect to the PSTN? What functions/processes is Asterisk responsible for and what functions/processes is SER responsible for? What handoffs are going on? Thank You, dave_rep@yahoo.com
