mod_xml_curl - missing dialplan variable (domain of originating user for blind transfer)
by Cal Leeming [Simplicity Media Ltd] 31 Dec '12

31 Dec '12

Hi guys, In a nut shell, it appears that when attempting to perform a blind transfer under certain conditions (explained below), mod_xml_curl does not expose the originating domain in a clean format. My initial plan was to find the point where these variable were being generated, look at what was available, then add an extra variable for the domain and submit a patch. Sadly my C isn't great and I hit a brick wall, so if anyone can help out, I will ensure the mod_xml_curl documentation is updated and/or assist with any patching/testing required. Please take the following scenario; * Extension 2000 calls an external number via a gateway (i.e. bridge sofia/gateway/name/e164_number_here). * Call connects fine, audio stays good, no disconnection problems etc. * Call is blind transferred to another extension As a result, the following is determined; * User initiating the blind transfer is 2000 * Domain initiating the blind transfer is c1881.voiceflare.co.uk * Destination number of the call is 447866123456 * Number to blind transfer to is 2001 * Call to mod_xml_curl is made It makes reference to the User in the following 'clean' variables (by clean, I mean variables that just contain 2000 and don't require mangling to extract the info); u'Caller-ANI': u'2000', u'Caller-Username': u'2000', u'Caller-Caller-ID-Number': u'2000', u'Hunt-ANI': u'2000', u'Hunt-Caller-ID-Number': u'2000', u'Hunt-Username': u'2000', u'variable_last_sent_callee_id_number': u'2000', u'variable_sip_from_user': u'2000', It also has the User in the following unclean variables; u'variable_bridge_channel': u'sofia/external/ 2000@c1881.voiceflare.co.uk:5060', u'variable_sip_from_uri': u'2000(a)89.238.182.137', u'variable_sip_full_from': u'"foxx" <sip:2000@89.238.182.137 >;tag=XryjFQp3rB2NF', u'variable_sip_h_Referred-By': u'"foxx" < sip:2000@c1881.voiceflare.co.uk:5060>', However, it only references the domain in the following unclean variables; u'variable_bridge_channel': u'sofia/external/ 2000@c1881.voiceflare.co.uk:5060', u'variable_sip_h_Referred-By': u'"foxx" < sip:2000@c1881.voiceflare.co.uk:5060>', u'variable_sip_refer_to': u'<sip:2001@c1881.voiceflare.co.uk:5060>', Lets say that we want to determine the user/domain that has initiated this transfer, doing so would mean mangling with one of those above variables, which seems a bit dirty (plus it is not clear which is the correct one to use). I have attached the SIP trace of the entire blind transfer event, and the full mod_xml_curl request being sent. If anyone could answer the following, it'd be much appreciated; * Should there be an improvement patch that exposes the domain of the user that originated the blind transfer? * Are there better/alternative ways to extracting the domain of the user that originated the blind transfer? Many thanks Cal

mod_xml_curl + variables documentation
by Cal Leeming [Simplicity Media Ltd] 30 Dec '12

30 Dec '12

Spent several hours working on further re-structuring the mod_xml_curl docs, but I'm still not happy with it :/ http://wiki.freeswitch.org/wiki/Mod_xml_curl As mod_xml_curl request variables can be very difficult to figure out, I have started to document which request variables apply where, which are common, which are section specific etc. However - there is also a huge lack of variable documentation, and although this isn't strictly a mod_xml_curl thing, it would benefit many others areas too if we had all these documented.* * Although the mod_xml_curl docs page isn't the proper home for variable descriptions, it will suffice for now until we have them all collected. For example: http://wiki.freeswitch.org/wiki/Mod_xml_curl#sip_user_agent http://wiki.freeswitch.org/wiki/Mod_xml_curl#sip_request_port Compared to: http://wiki.freeswitch.org/wiki/Variable_sip_user_agent http://wiki.freeswitch.org/wiki/Variable_sip_request_port To some extent, I think that the concept of having individual pages for each variable is not very user friendly - would anyone care to speculate on whether this should be phased out in favour of a single page with all the variables on? Either way, if anyone has maybe a spare 10 minutes to contribute towards getting these variables documented, it would really help reduce the work load (some are a simple Google job, others require trawling through source code).

Hi, Can we provide the switch.conf through xml_curl. I see freeswitch not requesting the switch.conf? I would like to eliminate all the .conf files except the xml_curl.conf. Does this possible? Which .conf files cannot use through the xml_curl? Thanks Lloyd

Looks like simple one, but I can't figure it out if there a way to stop a lua script invoked via luarun which is stuck in an infinite loop and won't terminate itself? Of if we can come up with a way to monitor the thread and stop it? Thanks, -- Muhammad Naseer Bhatti

Jingle updates since 2010 ?
by Ali Jawad 29 Dec '12

29 Dec '12

Hi Sometime in 2010, one of my employers wanted to use an xmpp server with jingle to be able to make pstn calls through freeswitch by sending the jingle call to freeswitch and freeswitch does convert to SIP. Anthony did help me at the time and the conclusion was Now I have to state the following. I have tried Freeswitch in client mode using the following two approaches 1. With A Gtalk account and a gtalk client, this worked flawlessly 2. With server XMPP servers and jingle clients all register but FS was not able to do Jingle to SIP conversion in this case. *The main reason as per FS developer Anthony is that jingle is a point to point protocol and FS was tested to work with Gtalk and telepathy. Note here that Freeswith does not use libjingle it uses it's own special jingle implementation* 3. Another Approach I use was the component mode with my XMPP server, everything worked right expect jingle to sip conversion !! :(. From http://www.alijawad.org/cms/index.php?option=com_content&task=view&id=21&It… Now, I do have a new employer requesting a similar scenario, and I would love to know if anything has changed since and if the scenario in question is now possible. Regards * *

caller-id-number not getting set
by sanjay soni 29 Dec '12

29 Dec '12

In all the dialplan examples (Both in the book and wiki) most places destination_number is being tested in the <condition>, BUT I want to do something based on caller-id-name / caller-id-number channel variables. But I see that all these variables (Caller-Caller-ID-Name, sip_callee_id_name, sip_auth_username, caller-id-name, caller-id-number) are empty. however, i see these values properly in the event being fired But not in the xml dialplan (Which is the place i want ot use them) ! What should I do ? Thanks Sanjay

failover when storing recordings
by Jayesh Nambiar 29 Dec '12

29 Dec '12

Hi All, Is there a way in freeswitch wherein if the call recording is not successfully stored, it can store it in some separate path? Basically the idea is, I am planning to use NFS for data storage. So freeswitch is actually storing the recordings on an NFS mounted directory. For some reason, if the NFS mount fails, or if the disc on the storage server is full or whatever may be the reason, could there be a way that freeswitch can store it on a separate directory which is local to the server. Does this sound like a feature or a requirement?? Thanks. --- Jayesh
