XML voicemail script / Is it possible to send more than one HTTP GET request per-script?

I am writing an XML script for the voicemail object in which I wish to send multiple HTTP GET requests.

Here's a simplified example:

<?xml version="1.0" encoding="utf-8" ?>

</function>

</voicemail>

This script when tested would send only the first HTTP GET request and ignore the second one.

Am I missing something? How do I solve this problem?

Aiman,

never tried that before, but it should work.

Keep in mind that the URL provided for the exec tag is queried and the content returned is used as voice mail script language. So it may well be that your first URL returns something that confuses the script processor.

I'd suggest that you tock the "trace" check mark in the voicemail object and then examine the trace.

Thanks for the quick reply Christoph.

Assuming the problem is that the first URL returns something that confuses the script, is there a way to make the script ignore whatever the url returns and continue running?

I am not interested in what the url returns (and can't control it) because the script is used to control doors and lights that support remote control using http. Is there a way to work around this issue?

no, the exec tag has no options.
When you have a Linux App Plattform at hand, you craft a little php script that throws away any returned content?

Now I know what I want for Christmas

Seems like a long walk for a short drink of water, but I can't think of an alternative right now so I'll work on that.

Thanks Christoph.

Re: XML voicemail script / Is it possible to send more than one HTTP GET request per-script?

Hello Aiman,

could you do an RPCAP trace with following options enabled

trace=active und $_trace=251

See http://wiki.innovaphone.com/index.php?title=Howto:Debug_your_own_PBX_voicemail_script for more info.

Please also activate All TCP/IP Trace to be able to see the HTTP traffic.

Best Regards
Andreas Fink

Hi Andreas,

Are you sure about the trace flag 251? I tried it and nothing relating to the voicemail script seems to show in the trace. So I did the trace as recommended in the wiki link you provided using the 123 trace. I'll copy the results (using 123) here.

The tested script:

<?xml version="1.0" encoding="utf-8" ?>

</function>

</voicemail>

The resulting trace (flag 123 + All IPv4 TCP/UDP Traffic):

As you can see, the script never makes it past the first exec command. On the receiving end of the http requests, the first request works as intended but the second request is obviously never received.

Let me know if I should try again with the 251 trace flag in case it is needed anyway.

Hi Andreas,

I'm not sure if this works, but if the exec is waiting for a return, try this.

<?xml version="1.0" encoding="utf-8" ?>

</function>

</voicemail>

Re: XML voicemail script / Is it possible to send more than one HTTP GET request per-script?

Tried it. It doesn't work past the first request unfortunately.

Unless I'm mistaken, out-error can't be assigned by the user, rather it is the result of executing the command.

Thanks for trying though.
