Simple and robust Linux command line SIP client/library

I'm looking for a SIP client on Linux which I could control through a pipe, or a high level library to incorporate one in my software. I tried Linphone, which is quite goo开发者_运维问答d, but seems to have some instabilities, as dropping sound when talking with an Asterisk server. I'm currently looking at OpalVoip, but I thought I'd ask to the experts... Thank you

This page lists just about all your options. sofia and sipx are used in popular VoIP applications so they are probably good bets.

I had success with Simple SIP SDK. It seemed more modern that other solutions I tried and which did not work. It also has OPUS support which I was looking for.

It is a bit of work to build from source. They provide a repository with built binaries, which I ended up using.

After installing:

sip-settings -a add 6010@172.31.0.1 1234678 <--password
sip-settings -a default 6010@172.31.0.1
sip-settings -a set 6010@172.31.0.1 sip.outbound_proxy=172.31.0.1
sip-register  <-- seems optional
sip-audio-session sip:5101@172.31.0.1

One last note, I had to download the source to get the instructions on how to install the binaries from the repositories for the various operating systems.

PJSIP is a good choice. Very robust, stable, feature rich.
