Generate 180/183 with SDP upon receipt of a 180 without SDP
Hi Folks, Does anybody know a way I can get FreeSWITCH to generate a 180 or 183 with SDP upon receipt of a 180 without SDP? Unless I'm being stupid (quite possible) I couldn't find an answer to this on the wiki, although lots around early media (I don't really want to resort to generating ringing for every call, in case the callee is genuinely engaged/busy for example). The context behind my enquiry is that I send traffic to another SIP carrier that then hands the traffic off at ISUP. Where the ISUP carrier sends back an ACM with a backward call indicator of "subscriber free" the carrier sends a 180 without SDP to me/FreeSWITCH assuming that any ringback tones will be generated by the SIP user agent (RFC 3398 blah, blah, blah). Any help much appreciated! Rgds, Mick Tel/SMS. +44(0)7967 594432 Fax. +44(0)7053 452429 Email/IM. mickstevens@yahoo.com Skype: mick_stevens www.facebook.com/mickstevens www.twitter.com/mickstevens
Hi Mick, What is the call flow in this case? I'm curious to know what call legs exist and where the 180/183 is and is not happening. FreeSWITCH generally does all this for you, so I suspect there's a gremlin in the works. Can you pastebin a console debug log w/ SIP trace? That may give the gang here just enough information to figure out what's going on. Thanks, MC On Mon, Oct 8, 2012 at 2:26 AM, Mick Stevens <mickstevens@yahoo.com> wrote:

Hi Michael, Wow, honoured & a bit starstruck by your reply in person (or do you celebs have somebody that replies for you ?)! Your FS books pretty much travel everywhere with me at the moment! Ok, but seriously, please excuse the poor but hopefully amusing/just about understandable call flow diagram attached. Basically in the 4th leg of the call (far right) an ACM is sent back to a Veraz switch (call leg 3) which sends us a 180 without SDP which we (FreeSWITCH, call leg 2) transit to the customer (1st call leg) without manipulation. The customer is apparently unable to generate ringing locally. So basically the question is can FS map/convert the 180 without SDP received into a 180/183 WITH SDP for onward transmission. Am trying to get a trace but unfortunately customer is not sending us traffic at the moment due to this "issue". Once again, excuse lack of wordsmithing/Visio/Powerpoint but travelling without my normal array of bells & whistles! <3 FreeSWITCH!

Mick, Think about what you are asking. FS or any sip entity has no message it can send durring an invite transaction, untill the 200 where it could specify the SDP. Also at the point of the SS7 switch, receiving an ACM, there could only be one way audio. The direction of the audio at this point, before the call is answered, CAN only be the backchannel. Is there a way to map back-channel-indecator values to sip responses in your switch? --Dave _____ From: Mick Stevens [mailto:mickstevens@yahoo.com] To: FreeSWITCH Users Help [mailto:freeswitch-users@lists.freeswitch.org], Michael Collins [mailto:msc@freeswitch.org], Seven Du [mailto:dujinfang@gmail.com] Sent: Tue, 09 Oct 2012 05:36:07 -0700 Subject: Re: [Freeswitch-users] Generate 180/183 with SDP upon receipt of a 180 without SDP Hi Michael, Wow, honoured & a bit starstruck by your reply in person (or do you celebs have somebody that replies for you ?)!

Hi Michael & Co, Now with traces attached... The customer is 86.166.113.42, FreeSWITCH is 85.133.61.23x & the Carrier is 125.236.36.3 Basically the carrier sends us a 180 without SDP (FreeSWITCH-Carrier Trace.pcap, packet 3...) which we transit back to the customer (Customer-FreeSWITCH Trace.pcap, packet 7). Is there a away we can modify our response upon receipt of the 180 without SDP to send a 180/183 with SDP? P.S. I made a couple of quick test calls to replicate this & I think I may have sent the customer leg of one & the carrier leg of the other (duh, sorry, only noticed this when I merged the traces together & the packets appears out of sequence). But the nos & principles involved are the same, hence the two files... Any help much appreciated.

"Note that this may cause undesirable effects, like ringing for 3 seconds that turns into a busy signal."
I wonder how you can avoid that? Consider this scenario: You receive 180 w/o SDP from far end You send 183 w/SDP ringing to your client The far end now sends a 183 w/SDP that contains a busy signal? What do you do there? -MC _________________________________________________________________________ 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 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
try set ringback=${us-ring} before you bridge. -- Seven Du Sent with Sparrow (http://www.sparrowmailapp.com/?sig) On Monday, October 8, 2012 at 5:26 PM, Mick Stevens wrote:
Hi Folks,
Does anybody know a way I can get FreeSWITCH to generate a 180 or 183 with SDP upon receipt of a 180 without SDP?
Unless I'm being stupid (quite possible) I couldn't find an answer to this on the wiki, although lots around early media (I don't really want to resort to generating ringing for every call, in case the callee is genuinely engaged/busy for example).
The context behind my enquiry is that I send traffic to another SIP carrier that then hands the traffic off at ISUP. Where the ISUP carrier sends back an ACM with a backward call indicator of "subscriber free" the carrier sends a 180 without SDP to me/FreeSWITCH assuming that any ringback tones will be generated by the SIP user agent (RFC 3398 blah, blah, blah).
Any help much appreciated!
