OK thanks i will wait for your clean code. Note: it's no problem for if you send me "hack" version already now, then i have already something to look at. -----Original Message----- From: pjsip-bounces@xxxxxxxxxxxxxxx [mailto:pjsip-bounces at lists.pjsip.org]On Behalf Of Lafras Henning Sent: 07-09-21 15:22 To: pjsip embedded/DSP SIP discussion Subject: Re: Example "Simple PJSUA" without soundcard At the moment my code is a bit of a hack, of pjsua_app.c, I am busy seperating it into a more sane structure, will advise once it looks ok. regards Lafras ----- Original Message ----- From: "B. van Klinken" <b.vklinken@xxxxxxxxx> To: "'pjsip embedded/DSP SIP discussion'" <pjsip at lists.pjsip.org> Sent: Friday, September 21, 2007 3:13 PM Subject: Re: Example "Simple PJSUA" without soundcard > Hello Lafras, > > Thanks. > > It is possible that you send me the code you used to initiate the splitcomb. > Myabe i could fin dout how to use, but it would be very much faster if i had > a reference example in source code.
