Hi, Wow thanks for answering so fast Chris. You are right I am using Raspbian (i tried Arch but im no linux expert so i wen't back) The Asterisk is on the server that it's a PC not on the pi. I already make it work using a USB webcam as a mic, i bougth a logilink usb sound card but pjsip doesn't like it ( from command line and even python alsa plays and records fine from that usb soundcard but 2.1 pjsip no), I also noticed that if no usb webcam it didnt start only to play incoming sound. I need it in two way audio so i won't bother using no input but i would like to make it work with the usb sound card or a usb mic rather that a more expensive logitech webcam. To make it work consistennty since it fails and gets stuck sometimes I added some daemons that kill revive the pjsic script :D Again many thanks and cya Kind Regards Jordi.

We have no need to take a mic input and so just are looking to have PJSIP as a dumb client accepting an inbound call and outputting the incoming audio stream via the 3.5 mm audio socket. At this point in time we didn't want to add a USB (or other) sound device, however, from what I am reading below, even a USB sound device isn't working that well. > > > > Has anyone had ay greater success with the Raspberry Pi?

Compile PJSIP with ALSA backend instead of PortAudio, and make sure the sample rate is 16KHz.
