Hi Nanang,
Thanks for the pointer. I realised the problem was in the ioqueue, but I
assumed the max was dynamically assigned based on the call count.
Unlucky choice of max calls caused that assumption and I should've
checked for a define before troubling you, so sorry about that. I have
since solved this by reducing my max calls to 30 and everything works.
However things aren't perfect. I did notice that when starting up my
app, I get an immediate crackle out of my media device. The crackle
lasts for a little under a second then stops. This doesn't happen every
time, but often enough for it to be annoying so I am trying to work out
what is sending this noise down to my device upon start up but I have no
idea.
Here is a code snippet of how I am doing this. I hope that it might be
useful to anyone else that needs to integrate an RTP stream into their
UA, and if anyone can see where the crackle problem would come from that
would also be great.
Thanks again Nanang.
Pierre

Subject: Re: Creating custom conf port in pjsua
Hi Pierre,
The limitation seems to come from ioqueue, i.e PJ_IOQUEUE_MAX_HANDLES
which by default is set to 64, and all of them are being used by
'calls' (currently media transports are precreated in PJSUA and when
you specify max calls = 32 it preserve 64 handles, RTP & RTCP for each
call). You can increase PJ_IOQUEUE_MAX_HANDLES by defining it (to a
bigger value than 64) in the config_site.h.

nanang
