Channel events

Hello I got two questions: a) How do I now if a UA is doing an outbound call, or if it's ringing on the UA? Tapi has two events for that: Offering and Alerting. The first one is when a UA is dialling someone, and the second when someone is ringing on the UA. b) How do I know which one that hangup? (If it was the UA or the calling user). Thanks, Jonas

extracting sip subject
by Madhuri Patwardhan 08 May '07

08 May '07

Hi, I need to extract the sip subject from the incomng sip call and initialize a variable with this value, which then gets used further. I went through the documentation on Freeswitch wiki and haven't found a way to extract sip subject from the incoming sip call. Is there a way to do this? From the documentation I realized that I could use application set to initialize a variable with this value.

.NET support
by Jason Steele 08 May '07

08 May '07

Hi all, I want to use Freeswitch for a fairly complex IVR application. I really don't want to do it in javascript and would much prefer to use C#. Can anyone tell me whether Freeswitch currently supports modules written in .NET languages? If so, how do I go about developing one and configuring Freeswitch to use it? If not is work currently in progress to provide this functionality? I see from previous posts that James Martelletti was pretty active in this area, are you still working on this James? I also noticed that mod_mono was recently removed from Freeswitch, but that there is a Freswitch.Net project within the solution. Has mod_mono been replaced by Freeswitch.NET? Many thanks, Jason Steele Jason Steele IT Director Office: +44 (0)1603 34 34 00 Support: +44 (0) 1603 34 00 00 email: jason.steele(a)rcsuk.co.uk <mailto:roy.ferris@rcsuk.co.uk> web site: www.rcsuk.co.uk This message and any attachments are intended for the addressee only and may contain confidential information.

Jitter problems
by Ivan C Myrvold 08 May '07

08 May '07

I am trying to get Freeswitch to work with my SIP provider, IP24, but I always get very bad sound in one direction. I made a wireshark trace, and looked at the jitter graph it produced. I made an incoming call from my mobile phone to Freeswitch via SIP provider IP24, PCMA codec: 1. http://www.myrvold.org/freeswitch/me2ip24.jpg , from freeswitch->ip24 2. http://www.myrvold.org/freeswitch/ip242me.jpg , from ip24->freeswitch There is a big difference in jitter between the two graphs, and the speech quality is very bad ip24->freeswitch (2). What can I do to fix the speech quality? Asterisk and OpenPBX (CallWeaver) have both excellent audio quality in calls through my SIP provider IP24. Here is a voip graph of the SIP call: http://www.myrvold.org/ freeswitch/graph.jpg Ivan

external RTPs/SDP manipulation
by David Villasmil Govea 07 May '07

07 May '07

Hello all, I need a signalling server, what I need it to do is the following, there are two scenarios: The network structure is this: ________ |RTP BOX |____________ |________| __|________ | END POINT | |___________| ________ | | FS |____________| |________| Scenario 1: Generate a call to and end-point specifying dynamically the ip/port for rtps and report back the end-point's rtps's ip/port. Scenario 2: Receive INVITES and report them walong with its rtp's ip/port and answer with a dynamically assigned the ip/port. The rtp's ip/port assigment is done dinamically on another box which soulh communicate with FS via a socket or a script. Does anyone knows wether it is possible at this pont? if it is, how go about this, pointing me in the right direction? I would prefer to do this via scripts (Perl, php) Thanks everyone.

No what I mean is.... Email me (just me not the whole list) and tell me the login and password to your sip provider account that is not working. Then I can log in and reproduce and discover the problem from my end. Once I figure it out then you can change the pass to something else.
