If you don't want to send 183, don't try to send early media. It's the only way. In the dialplan you posted, remove the line: <action application="playback" data="/tmp/test.wav"/> /Peter -----Ursprungligt meddelande----- Från: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] För Dennis Skickat: den 6 augusti 2012 12:58 Till: FreeSWITCH Users Help Ämne: Re: [Freeswitch-users] Early media: Sending 180 instead of 183? we are doing a lot with ISDN-connections, while ISDN in germany seems to be very different from the ISDN in the usa. our carriers asked us to only send a 180 instead of the 183 because, as i wrote above, 183 messages are not mapped reliable to ISUP as written in the specification ITU-T Rec. Q.1912.5. the a-leg sends an IAM or INVITE, but does not receive an answer - this can differ from a-leg to a-leg. we know, that this problem is quite special, but we have the same problems with different carriers. _________________________________________________________________________ Professional FreeSWITCH Consulting Services: consulting@freeswitch.org http://www.freeswitchsolutions.com FreeSWITCH-powered IP PBX: The CudaTel Communication Server http://www.cudatel.com Official FreeSWITCH Sites http://www.freeswitch.org http://wiki.freeswitch.org http://www.cluecon.com Join Us At ClueCon - Aug 7-9, 2012 FreeSWITCH-users mailing list FreeSWITCH-users@lists.freeswitch.org http://lists.freeswitch.org/mailman/listinfo/freeswitch-users UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users http://www.freeswitch.org !DSPAM:501fa15e32761376919998!
