<DIV>Since this is for use in external generated XML, and for the most part it should be code that is generating it, the easiest way to handle calls from gateways, is to back them with users in the directory. When A calll is from a gateway, simply do a set_user in your dialplan, and then a transfer back to the number dialed in the context ${user_context}, which will be set after you do the set_user. </DIV>
<DIV> </DIV>
<DIV>This way you don't have to do anything special for calls that come from a gateway, transfers and other things just work right.</DIV>

<DIV><BR></DIV>
<DIV>However, my previous comments about forcing sip_auth_realm/sip_auth_username are generally considered unsafe from a security point of view.</DIV>
<DIV><BR></DIV>
<DIV>If you force those variables, under some circumstances a blind transferred call from an external gateway could later on be considered an authorized internal user and lead to undesired behaviour.</DIV>
<DIV><BR></DIV>
<DIV>Forcing sip_invite_domain however is acceptable, as some request context will lose this information during a blind transfer or bridge.</DIV>
<DIV><BR></DIV>
<DIV>I am currently building up a spreadsheet of different call scenarios, along with the request variables for each one, so it is easy to see how the variables change depending on what event is happening.</DIV>

<DIV><BR></DIV>
<DIV>Thanks for the reply, yeah I spent some time looking at alternative ways and came up with one that seems to get the job done</DIV>
<DIV><BR></DIV>
<DIV>I am convinced now that there is no bug as such - but one thing that is absolutely clear, is that mod_xml_curl is in desperate need of normalization.. even if it was fully documented, some of the variants don't make logical sense. However, the information is there, and as long as you do the correct conditional checks, then it will work flawlessly.</DIV>
<DIV><BR></DIV>
<DIV>To make the authenticated domain stick when passing through to a gateway, we use the following;</DIV>
<DIV><BR></DIV>
<DIV><action application="bridge" data="{sip_auth_realm=${sip_auth_realm}}{sip_auth_username=${sip_auth_username}}{sip_invite_domain=${sip_from_host}}sofia/gateway/{{<A href="http://dst.gateway.name/">dst.gateway.name</A>}}/{{dst.gateway.fs_dial_prefix}}{{dst.dst_number_e164}}"/><BR><BR>The most important part of the above being;</DIV>
<DIV>{sip_auth_realm=${sip_auth_realm}}{sip_auth_username=${sip_auth_username}}{sip_invite_domain=${sip_from_host}}</DIV>
<DIV><BR></DIV>
<DIV>However, this alone doesn't deal with the fact that you have to look in different places for the correct variables depending on what the current call context is.</DIV>
<DIV><BR></DIV>
<DIV>To a certain extent, your own business logic will also determine which variables should be used, and a combination of conditional checks may need to be used in order to figure out which variable you should be using in the first place lol.</DIV>
<DIV><BR></DIV>
<DIV>Here are the patterns we have found so far - this is just an information dump for now, and later down the road I will update the mod_xml_curl documentation.</DIV>

<DIV>
<DIV>Last update, then I'm really going to sleep!
<DIV><BR></DIV>
<DIV>
<DIV>Apologies for the noise btw, in hindsight I should have collected all this info and posted in one go.</DIV>
<DIV><BR></DIV>
<DIV>I've tried enabling auth-all-packets (along with auth_calls), as I thought maybe having authentication on REFER packets might make a difference, but sadly it had no effect (the SIP headers show proxy-authorization in the REFER, but nothing extra showed in mod_xml_curl)</DIV>
<DIV><BR></DIV>
<DIV>I've managed to narrow down the circumstances in which this happens;</DIV>
<DIV><BR></DIV>
<DIV>CORRECT:</DIV>
<DIV><BR>* User receives call from gateway, blind transfer to another user (shows correctly as variable_dialed_user/variable_dialed_domain)</DIV>
<DIV>* User receives call from another user, blind transfer to gateway (shows correctly as variable_dialed_user/variable_dialed_domain)</DIV>
<DIV>* User receives call from another user, blind transfer to another user (shows correctly as variable_dialed_user/variable_dialed_domain)</DIV>
<DIV>* User makes call to another user, blind transfer to another user (shows correctly as variable_dialed_user/variable_dialed_domain)</DIV>
<DIV>* User makes call to another user, blind transfer to a gateway (shows correctly as variable_dialed_user/variable_dialed_domain)</DIV>
<DIV><BR></DIV>
<DIV>MISSING:</DIV>
<DIV><BR></DIV>
<DIV>* User makes call to a gateway, blind transfer to another gateway (no clean variables for domain)</DIV>
<DIV>* User makes call to a gateway, blind transfer to another user (no clean variables for domain)</DIV>
<DIV><BR></DIV>
<DIV>So, the problem seems to happen specifically when you blind transfer a call that is already in progress on a gateway, where the call was originated by a user and not a gateway.</DIV>
<DIV><BR></DIV>
<DIV>I did a bit more looking through code, added a few switch_log_printf() calls, and found that the following method is NOT called in those two scenarios where these variables are missing;</DIV>
<DIV>mod_dptools.c: "switch_call_cause_t user_outgoing_channel"</DIV>
<DIV><BR></DIV>
<DIV>This is about as far as I can go on this, as I just don't know enough about C to give any more in-depth info :/</DIV><SPAN><FONT color=#888888>

<DIV><BR></DIV>
<DIV>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.</DIV>
<DIV>
<DIV><BR></DIV>
<DIV>
<DIV>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.</DIV></DIV>
<DIV><BR></DIV>
<DIV>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.</DIV>
<DIV>
<DIV><BR></DIV></DIV>
<DIV>Please take the following scenario;</DIV>
<DIV><BR></DIV>
<DIV>* Extension 2000 calls an external number via a gateway (i.e. bridge sofia/gateway/name/e164_number_here).</DIV>
<DIV>* Call connects fine, audio stays good, no disconnection problems etc.</DIV>
<DIV>* Call is blind transferred to another extension</DIV>
<DIV><BR></DIV>
<DIV>As a result, the following is determined;</DIV>
<DIV><BR></DIV>
<DIV>* User initiating the blind transfer is 2000</DIV>
<DIV>* Domain initiating the blind transfer is <A href="http://c1881.voiceflare.co.uk/">c1881.voiceflare.co.uk</A></DIV>
<DIV>* Destination number of the call is 447866123456</DIV>
<DIV>* Number to blind transfer to is 2001</DIV>
<DIV>* Call to mod_xml_curl is made</DIV>
<DIV><BR></DIV>
<DIV>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);</DIV>
<DIV><BR></DIV>
<DIV>
<DIV> u'Caller-ANI': u'2000',</DIV></DIV>
<DIV>
<DIV> u'Caller-Username': u'2000',</DIV></DIV>
<DIV>
<DIV> u'Caller-Caller-ID-Number': u'2000',</DIV></DIV>
<DIV>
<DIV> u'Hunt-ANI': u'2000',</DIV></DIV>
<DIV>
<DIV> u'Hunt-Caller-ID-Number': u'2000',</DIV></DIV>
<DIV>
<DIV> u'Hunt-Username': u'2000',</DIV></DIV>
<DIV>
<DIV> u'variable_last_sent_callee_id_number': u'2000',</DIV></DIV>
<DIV>
<DIV>
<DIV> u'variable_sip_from_user': u'2000',</DIV>
<DIV></DIV></DIV>
<DIV><BR></DIV>
<DIV>It also has the User in the following unclean variables;</DIV>
<DIV><BR></DIV>
<DIV> u'variable_bridge_channel': u'sofia/external/<A href="http://2000@c1881.voiceflare.co.uk:5060">2000@c1881.voiceflare.co.uk:5060</A>',</DIV>
<DIV></DIV></DIV>
<DIV>
<DIV> u'variable_sip_from_uri': <A href="mailto:u%272000@89.238.182.137">u'2000@89.238.182.137</A>',</DIV>
<DIV> u'variable_sip_full_from': u'"foxx" <<A href="mailto:sip%3A2000@89.238.182.137">sip:2000@89.238.182.137</A>>;tag=XryjFQp3rB2NF',</DIV></DIV>
<DIV>
<DIV> u'variable_sip_h_Referred-By': u'"foxx" <<A href="http://sip:2000@c1881.voiceflare.co.uk:5060">sip:2000@c1881.voiceflare.co.uk:5060</A>>',</DIV></DIV>
<DIV><BR></DIV>
<DIV>However, it only references the domain in the following unclean variables;</DIV>
<DIV><BR></DIV>
<DIV> u'variable_bridge_channel': u'sofia/external/<A href="http://2000@c1881.voiceflare.co.uk:5060">2000@c1881.voiceflare.co.uk:5060</A>',</DIV>
<DIV> u'variable_sip_h_Referred-By': u'"foxx" <<A href="http://sip:2000@c1881.voiceflare.co.uk:5060">sip:2000@c1881.voiceflare.co.uk:5060</A>>',</DIV>
<DIV> u'variable_sip_refer_to': u'<<A href="http://sip:2001@c1881.voiceflare.co.uk:5060">sip:2001@c1881.voiceflare.co.uk:5060</A>>',</DIV>
<DIV><BR></DIV>
<DIV>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).</DIV>
<DIV><BR></DIV>
<DIV>I have attached the SIP trace of the entire blind transfer event, and the full mod_xml_curl request being sent.</DIV>
<DIV><BR></DIV>
<DIV>
<DIV>If anyone could answer the following, it'd be much appreciated;</DIV>
<DIV><BR></DIV>
<DIV>* Should there be an improvement patch that exposes the domain of the user that originated the blind transfer?</DIV>
<DIV>* Are there better/alternative ways to extracting the domain of the user that originated the blind transfer?</DIV></DIV>
