This repo conains examples of opensips configuration files. An opensips.cfg contains parameters that control the OpenSIPS core and modules. Also congains call routing logic.

To test validation of cfg file run run -C which returns 0 if ok and -1 if faulty

opensips -C opensips.cfg

After instalaltion check the version of opensips

opensips -V

note : match the opensips version with module version to avoid usuage of depricate functiosn or params . Infact opensips itsefl throws a warhning when incompatible version of core and modules are loaded together such as

Jul  5 08:53:49 [13720] ERROR:core:version_control: module version mismatch for signaling; core: opensips 2.2.7 (x86_64/linux); module: opensips 3.0.0-beta (x86_64/linux)

or
