Just tried to search around regarding this issue, but I couldn't find much: - there is a report that on some devices APS won't work with old firmware versions. - binary compatibility issue, problem may be caused by simple mistake by using wrong SDK version (e.g: on FP1 devices, you should use FP1 version of APS SDK & apsserver2.sis). > > by the way, i tried FRING also. i found they takes adventage on APS as well > and found it can work on all the devies that i tried. Any idea? > Sorry, no. However, there are other APIs for audio routing: - Audio Routing API, an easy patch needed (http://lists.pjsip.org/pipermail/pjsip_lists.pjsip.org/2008-July/003969.html) - VoIP Audio Service API, not implemented (yet) in PJSIP.
