Hello,
wondering if anyone here is aware of a lightweight sip app that can answer a call, play some file and/or do echo mode, mainly targeted at using it for basic sip routing and call testing. Of course I know that Asterisk and FreeSwitch (or even SEMS) can do that, but they have many dependencies, requiring quite some resources to run them, so I thought maybe someone here figured out different solutions, eventually cli based apps like pjsua or baresip. GUI apps for Linux are also fine if they can be configured for such behaviour.
Cheers, Daniel
