Greeting PJSIP developers, We are using PJSUA for specific application. we have 16 channel DSP that handle RTP/PCM transcoding .we want to use PJSUA as SIP to ISDN gateway app without any media capbilities(for 128 channels). at one side,there will be PJSUA app and other side will be tradiotnal PBX system(PCM). we have studied PJSUA-APP but its so tightly bundled with PJ-MEDIA. for example, pjsua_make_call() and on_incoming_call() handle media also. we can get all SIP to ISDN signalling done creating command interface between PJSUA-app and our application.But not sure how transfer recieved RTP packets to/from underlying DSPs directly without PJSIP transcoding it. your help will be greatly appreciated !! Regards, Kiran Bhosale

maybe this is your looking for https://trac.pjsip.org/repos/wiki/3rd_Party_Media_20 regards, Gang On Mon, Oct 17, 2016 at 11:42 PM, Kiran Bhosale <kbopensource2@gmail.com> wrote: > Greeting PJSIP developers, > > We are using PJSUA for specific application. > we have 16 channel DSP that handle RTP/PCM transcoding .we want to use > PJSUA as SIP to ISDN gateway app without any media capbilities(for 128 > channels). at one side,there will be PJSUA app and other side will be > tradiotnal PBX system(PCM). we have studied PJSUA-APP but its so tightly > bundled with PJ-MEDIA. for example, pjsua_make_call() and > on_incoming_call() handle media also. > we can get all SIP to ISDN signalling done creating command interface > between PJSUA-app and our application.But not sure how transfer recieved > RTP packets to/from underlying DSPs directly without PJSIP transcoding it. > > > your help will be greatly appreciated !! > > > Regards, > > Kiran Bhosale > > _______________________________________________ > Visit our blog: http://blog.pjsip.org > > pjsip mailing list > pjsip@lists.pjsip.org > http://lists.pjsip.org/mailman/listinfo/pjsip_lists.pjsip.org > >
