Josh Benson of Open Source Society tells us how pjsua can be used as fully featured SIP client to solve real life problems in PJSIP: Command-Line VoIP Client for Linux:
Some time ago, I was tasked at work with finding an IP telephony client that used the SIP protocol, ran on linux, and did everything from the command line. The goal was to have a program that could be deployed at remote networks to test the quality and performance of VoIP calls between the remote site and our central Asterisk VoIP server.

Josh has it spot on. While pjsua is intended primarily as the reference implementation of PJSIP (command line programs are always easier to learn than GUI), it is also intended to have the full features of a SIP client. Softphones with pretty GUI are easier to use, and they are also easier to find, but for some specific tasks, sometimes we have to revert back to using the good old console application, and that’s where pjsua fits the bill.
I’m glad that Josh and others find it useful. Thanks Josh for sharing your experience.

Could u please send me all the details of compiling and building pjsip on ARM and also send any changes made in build.mak and config_site.h
Waiting for ur reply
Thanks

I share the belief the command line SIP clients are useful. Unfortunately, from what I’ve seen so far, they’re not as straight-forward to use as GUI clients. You might have to dig through the docs to figure out how to use it with your specific IP PBX, etc.
And some like PJSIP require you to compile from source. Would be nice to have pre-built binaries for those who can’t or don’t know how to compile the source.
[…] the open source time travel project (I kid you not), has released PuppySIP, which wraps the command line SIP client pjsua. Puppy Linux is one of the smallest (if not THE smallest) Linux distribution around. I use it […]
Man, this thing rocks. I just found out about it and compiled it; I was looking for something just like this for the same reason as Josh. For testing remote voip clients, this thing is invaluable. Now, I have to wrap my head around their sketchy documentation.. but otherwise, an excellent tool to have.
kitten,
If you can let us know which bits of the sketchy documentation you want us to elaborate on, we’ll try to improve it.
Thanks for your comment!
