ISUP manipulations using external routing script
« on: July 29, 2015, 05:09:59 AM »
Hi,

I am trying to add ISUP data to the incoming SIP packet using external PHP module and then route it out to SIP-I provider.
When receiving an incoming call on 123123123 I need to encapsulate some ISUP data and then route the resulting SIP packet further to the provider.

my regexroute:
Code: [Select]
^+123123123.*=external/nodata/ss7-out.php
Code: [Select]
#!/usr/bin/php -q
<?php
require_once("libyate.php");

syslog(LOG_INFO'YATE log');

Yate::Init();
$ev=Yate::GetEvent();

syslog(LOG_INFO'YATE ev is ' $ev->name);

switch (
$ev->name) {

case 
"call.route":
syslog(LOG_INFO'YATE inside call.route - never happens');
break;

case 
"call.execute":
syslog(LOG_INFO'YATE inside call.execute');

$ev->SetParam("message-prefix","isup.");
$ev->SetParam("isup.message-type","IAM");
...(list 
of parameters here)

$ev->retval "sip/sip:+123123123@sip.provider.com:5060";
$ev->handled true;

$ev->Acknowledge();
$ev false;

break;

}

Yate::Output("PHP: bye!");
/* vi: set ts=8 sw=4 sts=4 noet: */
?>


In this case the call is answered and hangup with 1 second length and the call is never forwardd to the provider.
In case I remove Acknowlege() then I get "Service Unavailable" with no connection attempts as well.
Can you please point me what I am doing wrong here?

Thanks,
Andrei
