Hi , I tried what you told me to do , but i have a problem. When I send an re-invite message, and i recieve an 200 OK sip message ; the pjsua will not respond by an ACK message .and it will send more invite message. could you help me to resove this , I think that's a problem with the function " inv_on_state_confirmed" Thanks for helps Message: 3 Date: Wed, 09 Jun 2010 18:06:36 +0200 From: Klaus Darilion <klaus.mailinglists@xxxxxxxxx> To: Hadj Amor Hassen <hassen.hadjamor at gmail.com> Cc: pjsip embedded/DSP SIP discussion <pjsip at lists.pjsip.org> Subject: Re: two pjsip stack on the same computer Message-ID: <4C0FBC0C.50906 at pernau.at> Content-Type: text/plain; charset=ISO-8859-1; format=flowed Hi! it depends on which API you use. If you use pjsua-lib API then you can register different transports for the interfaces: Use pjsua_transport_create: http://www.pjsip.org/pjsip/docs/html/group__PJSUA__LIB__TRANSPORT.htm#g1c077d205f7df9fae39a179b2fe47533 provide in the pjsua_transport_config http://www.pjsip.org/pjsip/docs/html/structpjsua__transport__config.htm the "bound_addr" member. The create an account configuration and set the "transport_id" member: http://www.pjsip.org/pjsip/docs/html/structpjsua__acc__config.htm Then add the account: http://www.pjsip.org/pjsip/docs/html/group__PJSUA__LIB__ACC.htm#gd6e01e4e7ac7c8b1d9f629a6189ca2b2 I have not done that yet, but I think it should work.
