<p class=MsoPlainText>Hello,<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>Sent this post a couple of weeks back. Still trying to
find a solution, so <o:p></o:p></p>
<p class=MsoPlainText>trying again and see if anyone has any thoughts!<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>I am trying to send CUSTOM NOTIFY events to devices,
using the ESL interface <o:p></o:p></p>
<p class=MsoPlainText>with a PHP script of the following form. I am having
partial success, but <o:p></o:p></p>
<p class=MsoPlainText>coming up against problems when using with an outbound
SIP proxy:-<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText> $e = new
ESLevent("NOTIFY");<o:p></o:p></p>
<p class=MsoPlainText>
$e->addHeader("profile", "internal");<o:p></o:p></p>
<p class=MsoPlainText> $e->addHeader("from",
"1020");<o:p></o:p></p>
<p class=MsoPlainText> $e->addHeader("to-uri",
"<a href="sip:1019@192.168.2.3:5063;fs_path=sip:82.24.214.226:5063">sip:1019@192.168.2.3:5063;fs_path=sip:82.24.214.226:5063</a>");<o:p></o:p></p>
<p class=MsoPlainText> $e->addHeader("from-uri",
"<a href="sip:1020@pbx.rm.com">sip:1020@pbx.rm.com</a>");<o:p></o:p></p>
<p class=MsoPlainText> $e->addHeader("host",
"pbx.rm.com");<o:p></o:p></p>
<p class=MsoPlainText> $e->addHeader("event-string",
"check-sync");<o:p></o:p></p>
<p class=MsoPlainText> $e->addHeader("content-type",
"application/simple-message-summary");<o:p></o:p></p>
<p class=MsoPlainText> $e->addBody("ok");<o:p></o:p></p>
<p class=MsoPlainText> $res =
$sockFSServerCommand->sendEvent($e);<o:p></o:p></p>
<p class=MsoPlainText><o:p> </o:p></p>
<p class=MsoPlainText>In our setup, we have several FreeSwitch boxes sitting
behind two OpenSIPS load <o:p></o:p></p>
<p class=MsoPlainText>balancers. These Load Balancers handle registrations,
etc. When we originate <o:p></o:p></p>
<p class=MsoPlainText>calls from FreeSwitch, we use an originate URL of the
form <o:p></o:p></p>
<p class=MsoPlainText>(<a
href="mailto:sofia/internal/1001@sip.redmatter.com;fs_path=sip:84.45.30.2">sofia/internal/1001@sip.redmatter.com;fs_path=sip:84.45.30.2</a>),
<o:p></o:p></p>
<p class=MsoPlainText>and use fs_path to push the sip call out via the right
load balancer/ proxy. <o:p></o:p></p>
<p class=MsoPlainText>This works perfectly.<o:p></o:p></p>
<p class=MsoPlainText> <o:p></o:p></p>
<p class=MsoPlainText>So, with the custom NOTIFY’s I also need to make
them follow the same path. <o:p></o:p></p>
<p class=MsoPlainText>As mentioned, we already have the contact string in our
hand from the OpenSIPS <o:p></o:p></p>
<p class=MsoPlainText>registration server, but can’t see how I can use
that plus force the outbound <o:p></o:p></p>
<p class=MsoPlainText>path for the Notify. Was thinking I could use fs_path in
the uri (as above) <o:p></o:p></p>
<p class=MsoPlainText>but doesn’t seem to work, i.e. the wrong IP is
used, and NOTIFY is messed <o:p></o:p></p>
<p class=MsoPlainText>up somewhat (see example below)! Maybe another
combination I am missing! <o:p></o:p></p>
