I'm using the opal module, since mod_h323 is not available in Windows yet. We're not so dependant of all the correct release codes etc, we use it mostly for ASR and voicemail applications, but I do know there have been discussions about this on the mailing list. My recommendation is to use SIP to the IPO instead (mostly beacuse SIP is much better supported by FS), we're using that more and more. /Peter Från: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] För Tihomir Culjaga Skickat: den 10 februari 2010 21:27 Till: freeswitch-users@lists.freeswitch.org Ämne: Re: [Freeswitch-users] h323 - sip call is not working On Wed, Feb 10, 2010 at 8:42 PM, Peter Olsson <peter.olsson@visionutveckling.se<mailto:peter.olsson@visionutveckling.se>> wrote: I've been running both h323 and SIP between FS and Avaya IPO for some time. No problems at all. :) But make sure to enable h323 fast start and disable "direct media path" in the IPO, if I remember correctly these where the only two parameters that made any real difference for me. But I do recommenf to use SIP, since it's much better supported by FS. /Peter Peter, what H323plus version are you using ? did you noticed q931 release cause is not mapped H323 => SIP correctly ? !DSPAM:4b73196232931389031035!
