SIP-Client for Raspberry Pi that works from command line?

Question

i want to use my raspberry pi as a SIP/VOIP-Phone, just controlling the RPI via SSH.

I found some tutorials and it seems that Twinkle is one of the most useful apps for that.

So i successfully installed twinkle on my RPI, one SPI-Client on my Android-Phone and for know i am able to send text messages from one to another.

The thing is: I have to use the Twinkel GUI with X-Server-forwarding (currently using MacOS with X11 and iTerm).

But i kind of want to automate the whole process, like using twinkle from command line, controll it with scripts etc.

So, obviously twinkle is not made for that. (there dont even is a documentation for the account-config-file, so i had to struggle through that x11-forwarding-stuff)

So, my final question is: Is there comparable SIP-client for the RPI that can be controlled via CLI?

any hint is highly appreciated. While googling this question i just found projects working with asterisk-server on the RPI or attaching displays to it - but thats not what i am looking for...

cheers and thanks

Answer 1

I am doing the same thing and I came across additional options so far:

1. Linphone: Easy to install but I fail to make phone calls
   RaspberryPI: Making SIP outbound calls using linphonec or an alternative SIP soft phone

2. Ring (formerly SFLphone): Looks promising but needs to be installed from source
   Installing the "ring.cx SIP client" on a Raspberry PI.
   Update: Also check out @aberaud's answer below

3. PJSIP (C Library)

   • Recommended by this tutorial
   • Compile and Install on Raspi

Twinkle CLI

From the SFLphone mailing list I got this feedback, which might help you:

I'm interests to known if the project write something for that. By the pass, I used Twinkle SIP client that permit to pass command to an already launched processus that permit for instance to answer an incoming call. It was really cool and permit me to map some keyboard shortcuts to control my phone without to switch desktop and find the good windows.

After some search, I'm found some old scripts that permit to control old versions of sflphone by using it's DBUS API. Inspire by this scripts, I wrote my own, compatible with the version of sflphone I used (1.4.1 in Debian Wheezy) :

It's work weel and I'm use it every day. Call transfer does not work on my desktop but it seam to be a bug on version 1.4.1 of sflphone.

BTW: twinkle --help shows the following:

--cmd <cli command>
    Instruct Twinkle to execute the CLI command. You can run
    all commands from the command line interface mode.
    When Twinkle is already running, this will instruct the running
    process to execute the CLI command.

    Examples:
    twinkle --cmd answer
    twinkle --cmd mute
    twinkle --cmd 'transfer 12345'

I had no luck so far myself but I really want to get this to work too.
