Re: [Freeswitch-users] Early media: Sending 180 instead of 183?
If you do playback before you answer the call - that IS early media. If you answer the call before playback it will not send 183. But if you want to play it using early media it's just not possible to play it without using 183. /Peter -----Ursprungligt meddelande----- Från: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] För Dennis Skickat: den 6 augusti 2012 12:19 Till: FreeSWITCH Users Help Ämne: Re: [Freeswitch-users] Early media: Sending 180 instead of 183? in this special case, we do NOT have an outgoing channel and we do ALWAYS use ignore_early_media, if we have an outgoing channel.... we do/want the following: incoming call -> playback audio to caller -> hangup (no bridge or anything else) out test-dialplan is as follows: <extension name="test"> <condition field="destination_number" expression="^01234567$"> <action application="ring_ready"/> <action application="set" data="ignore_early_media=true"/> // with, ans without this line <action application="playback" data="/tmp/test.wav"/> </condition> </extension> everything would work with only the 180 - as soon as the 183 is sent, problems can come up. the 183 is simply to much in this case. _________________________________________________________________________ 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:501f980b32761254510098!
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.
