H Extension Isn’t Processed After Call File Finishes.

Hi all,

I’m trying to build a fax relay mechanism where faxes come in and get relayed out to their final destination. I’m using the h extension to store various results from both legs. This data is being saved correctly for the first (receiving) leg. The second leg isn’t calling the h extension when it’s finished. The second leg is being initiated by a .call file like:

Channel: local/1505xxxxxxx@context Application: sendfax Data: /tmp/voice11-voice11-1392668806.182025.tiff,zfds WaitTime: 90
MaxRetries: 2
Account: vFax CallerID: “Fax” <505xxxxxxx>

The h extension calls an agi scrip that logs a bunch of information about the fax attempt. Works just fine when I receive a fax. But there is no sign of it in the logs for the sending leg of the fax.

Is there something I need to do in order to get the h extension to get called?

Mike.

  • Would the ‘g’ dial() option help?

    “Proceed with dialplan execution at the current extension if the destination channel hangs up.”

    It won’t take you to h, but it may allow you to do what you need to do

  • I’m actually a bit confused about what channel(s) are executing the
    ‘h’ extension. From the description in OP’s e-mail, it sounds as if at least one channel is dropping into the ‘h’ extension, and some channels are not. Which channels are they? If it is the outbound channel, then since that channel doesn’t execute dialplan, it will never get put into the ‘h’ extension, unless you use the Dial application’s ‘e’ option. If you want hangup logic and you’re using Asterisk 11+, you could also use a hangup handler on the outbound channel.

    But otherwise, I would expect that the ‘h’ extension would always be fired for a channel executing dialplan, so long as it is in the same context.

  • Matthew,

    I don’t think I’ve been as clear as I’d like.

    I’ve got some fax-connected TA’s that make outbound calls. The dial plan routes those calls to an AGI script that captures the fax image, the destination phone number, and creates a call file to deliver the image to the destination.

    The first outbound call executes the h extension when it is hung up. The second call, created by the call file, doesn’t execute the h extension, even though I use the dialplan to actually route the outbound call.

    So, I’m ending up with statistics on the reception of the fax, but not the final delivery.

    Does that make more sense?

    Mike.
