SDP issue receiving calls from SIP connection
by Kirk Bateman 13 Aug '08

13 Aug '08

Afternoon everyone, I have a bit of a problem with Freeswitch receiving RTP INVITEs from my SIP provider (tesco's internet phone ... I know SIP isn't supported technically, but it sort of works...) Freeswitch (sofia) seems to be whinging about the INVITE SDP format ... but I'm not sure why ... here's a dump of my log / trace, anyone got any clues, I've tried adding extra codecs to my list and setting the late negotiation but that doesn't seem to fix it ... (registration all works fine by the way ...) ------------------------------------------------------------------------ INVITE sip:MY_PHONE_NUMBER@MY_IP_ADDRESS:5060;transport=udp SIP/2.0 Via:

presence states
by Jonas Gauffin 13 Aug '08

Is it possible to get FS to just report open/closed (avail/not avail) instead of all specific call states? Maybe a toggle for that or something?

Call broadcasting
by Ruchir Brahmbhatt 13 Aug '08

13 Aug '08

Hi, Which is the best method of doing call broadcasting in freeswitch? In asterisk we can do this by creating call files and asterisk handles the rest. How does freeswitch offers this feature? Do we need to use mod_event_socket only? Is it faster enough for this requirement?

How we can control calls using Java
by Adeel Ansari 13 Aug '08

13 Aug '08

Hi, I have managed to hook my Java program in. Now, looking for some hint, how we can control the call. Actually, I need to make a call, on genuine mobile phone, using Gizmo5 VoIP network. Furthermore, from where I can get the Mod-Java API documentation. -- Best, Adeel Ansari http://www.linkedin.com/in/adeelansari

Unable to receive calls from external sources.
by Rocky Hetherington 12 Aug '08

12 Aug '08

I'm having trouble getting FreeSWITCH to work properly and was hoping someone would be able to give me a few pointers. I've looked through all the documentation, examples and large chunks of the mailing list but i just can't make heads or tails of things. First i should give a bit of information on what i want to do. I'm going to be running FreeSWITCH on Xen virtual server with a public IPv4 IP. The OS is Debian Etch and lets call the machine "server1.example.org". It will be serving calls for the example.org domain and the relevant SRV records have been set up in the DNS. What i want to set up FreeSWITCH to do is have two users (we'll call them Bert and Fred). I want the two users to be able to call between themselves using either their relevant <USER>@example.org SIP URI or an extension number (2378 for Bert and 3733 for Fred). I also want users outside the domain to be able to call either user using their SIP URI and extension (and also via SipBroker). In addition Bert has two XMPP accounts. One is a Google Talk account and the other is a local account on an OpenFire server (also running on server1.example.org) I would like FreeSWITCH to listen on these accounts for incoming Jingle calls and then pass them through to Bert's registered SIP device. If the user is not currently registered i would like FreeSWITCH to take a voicemail. I would also like users to be able to dial out using SIP URIs and SipBroker prefixes. I don't currently need for it to dial out to the PSTN using a gateway. What i have done so far: Following the instructions in the Wiki i have created some Debian packages of FreeSWITCH 1.0.1. These are installed and the server is running fine. Other than the three changes outlined below the server is completely stock config. I have edited conf/vars.xml and changed the following line to: <X-PRE-PROCESS cmd="set" data="domain=example.org"/> I have deleted the local extensions from conf/directory/default and created two users called bert and fred using files such as this: conf/directory/default/bert.xml: <include> <user id="2378" mailbox="2378"> <params> <param name="password" value="password"/> <param name="vm-password" value="1000"/> </params> <variables> <variable name="accountcode" value="2378"/> <variable name="user_context" value="default"/> <variable name="effective_caller_id_name" value="Bert"/> <variable name="effective_caller_id_number" value="2378"/> </variables> </user> </include> By default FreeSWITCH comes enabled to talk between internal users out of the box, so that works, although i need some way of aliasing the username "bert" to the extension 2378. I understand that FreeSWITCH uses something called contexts and the default context is not available to the public and i need to bridge to it, but i can't seem to figure out how to do it properly. I created a file conf/dialplan/extensions/bert.xml containing the following that i pieced together from the documention, but it doesn't seem to work: <include> <extension name="bert"> <condition field="destination_number" expression="^(bert|2378)$">   <action application="bridge" data="sofia/internal/2378%example.org" /> </condition> </extension> </include> (the commented out lines are previous lines i tried (one at a time) which also failed). I also tried adding the above (excluding the <include> tags) to the conf/dialplan/public.xml with no success. I then fire up my Gizmo softphone and attempt to connect from my Gizmo account using my SIP URI (bert(a)example.org) The FreeSWITCH logs indicate that it is hitting my server but is rejected: 2008-08-10 17:20:23 [DEBUG] mod_event_socket.c:1396 mod_event_socket_runtime() Socket up listening on 127.0.0.1:8021 2008-08-10 17:21:23 [DEBUG] sofia.c:3134 sofia_handle_sip_i_invite() IP 198.65.166.131 Rejected by acl domains.

I'm unsure why FreeSWITCH believes that my Gizmo account is meant to be a local user, and am unable to find any documention on adding a domain to the directory. If anyone could just tell me how to allow external SIP calls to be passed through to local users i would be content to leave the voicemail, Jingle and outbound calls until a later time when i have a better understanding of FreeSWITCH. Hope someone can help. Thanks.

SIP/2.0 407 Proxy Authentication Required
by Shehzad Pankhawala 12 Aug '08

Hi all, As H323 is not currently supported, I need to configure freeswitch to route calls to Yate2 to process my H323 calls and vice versa. For that I created the gateway in sip_profiles/external.xml <profile name="yate"> <gateways> <gateway name="192.168.1.23"> <param name="realm" value="192.168.1.23"/> <param name="extension" value="1001"/> </gateway> </gateways> <settings> <param name="debug" value="1"/> <param name="rfc2833-pt" value="101"/> <param name="sip-port" value="5060"/> <param name="dialplan" value="XML"/> <param name="dtmf-duration" value="100"/> <param name="codec-prefs" value="$${default_codecs}"/> <param name="codec-ms" value="20"/> <param name="use-rtp-timer" value="true"/> <param name="rtp-timer-name" value="soft"/> <param name="rtp-ip" value="auto"/> <param name="sip-ip" value="auto"/> <param name="accept-blind-reg" value="true"/> <param name="nonce-ttl" value="60"/> <param name="auth-calls" value="false"/> </settings> </profile> _______________________________ Note xxx.23 is IP of yate and xxx.22 is ip of freeswitch I have also created the user in directory <include> <user id="4444" mailbox="4444"> <params> <param name="password" value="1234"/> <param name="vm-password" value="4444"/> </params> <variables> <variable name="accountcode" value="4444"/> <variable name="user_context" value="default"/> <variable name="effective_caller_id_name" value="4444"/> <variable name="effective_caller_id_number" value="4444"/> </variables> </user> </include> ______________________________________________ Now for the same freeswitch user I have created Yate Line on Yate server in accfile.conf (just like gateway in freeswitch) [MyFS] enabled=yes protocol=sip username=4444 description=FS account interval=600 formats=alaw,mulaw,gsm authname=4444 password=1234 number=4444 domain=192.168.1.22 registrar=192.168.1.22 To route calls from Yate to freeswitch I have created the folowing regexroute.conf entry of Yate server ^1001$=sip/sip:1001;line=MyFS; ;this means that calls dialed to 1001 will be routed to 1001 Freeswitch server. Then I dial from user registerd on Yate to 1001 The call is not processed of freeswitch at all, but while i put ngrep on port 5060 on server Freeswitch I found the following sequences of SIP messages: ___________________________________________ U 192.168.1.23:5060 -> 192.168.1.22:5060 INVITE sip:1001@192.168.1.22 SIP/2.0.

Re: [Freeswitch-users] [Sofia-sip-devel] SDP issue receiving calls from SIP connection

A partial solution, I've not figured everything out, but suspect it might cause issues elsewhere to do with codec selection, however ... I've added "." to the sdp_parse (parse_rtpmap)... so in the token call it allows ALPHA DIGIT "-." Works nicely now (so far), realised that all my codecs from the Tesco INVITE were just becoming G/<bitrate> Cheers Kirk 2008/8/12 Pekka Pessi <ppessi(a)gmail.com> > 2008/8/12 Kirk Bateman <kirk.bateman(a)gmail.com>: > > I've just noticed that all the rtpmap codec entries (from my Tesco > INVITE) > > generally have a "." in the token name ... it seems that sofia sdp_parse > > doesn't allow this. > > > > It seems valid according to the rfc 4566 ? > > The SDP parser has not been completely updated to RFC 4566. > > http://sofia-sip.sourceforge.net/refdocs/sofia_sip_conformance.html#4566 > > -- > Pekka.Pessi mail at nokia.com >

Just played with the test_sdp tool ... looks like the issue might actually be the clock rate for format 125 ... tool says its invalid... Cheers Kirk
