Hi,
I have been trying pjsua application in a Debian Lenny box and all has
worked out of the box. Now I was trying it in a laptop and I'm experiencing
an issue I don't know how to solve.
I'm streaming a PCMA WAV file from A to B. Laptop is B. I can play the file
locally in B but I'm unable to play it when establishing a SIP session with
A; in fact, I can't establish any SiP session with A because pjsua gets
stuck when configuring the audio device:

This is the point where pjsua gets stuck. If I add the --null-audio option
the SIP session is properly established and the audio is received although
it is not played (I know it is received because I can play it with Wireshark
when packets are captured).
So, it seems it's a hardware-related issue but I don't know how to solve it.
I would like to know if anyone has experienced the same problem or if I
could get any help on this. This is the information about the audio device,
in case it helps:
