QUESTION Play audio after caller hangs up for paging system

[michaelb]

Hope this makes sense, I'll try and explain it as best as I can.

I'm installing a new system to replace an Avaya one. They have a pager system that plugs directly into one of the cards on the Avaya. I have tried to simply put in a new extension on a FXS port directly wired into the pager, but it just heavily distorts the phone ringing sound, and doesn't pick up. I believe that this is because the Avaya was sending just the audio from the call out on that line through the card.

So, I've built a device out of an old corded phone and an Arduino that now sits in the middle between the FXS and the pager, it's designed to detect ringing, answer the call, and allow the audio to be transmitted for 10 seconds, before closing the call physically, like any other corded phone would.

The problem is this: If the extension calling the paging extension (501) hangs up before the end of that 10 seconds, I get the 'beep beep beep beep' sound of the line being disconnected until the 10 seconds are up. I'd really like it to play an audio file after the caller hangs up.

Why? I think that if i upload a blank wav file in the correct format and of length 10 seconds, that would keep the beep beep sound from playing across the output.

I think it should be possible creating a custom configuration, but I'm not familiar enough to know where to start. Any thoughts would be greatly appreciated.

Thanks!

You probably need a matching transformer to match the impedance of the FXO (600 ohms) to Microphone input (1.2 K ohms)

My choice:

Modify an old sip phone to auto-answer and have speaker or handset go to amplifier input - may need matching transformer. Inside user just dials ext to this phone. I might create a custom context that when dialed will record messages from inside caller and use callfile to dial phone and play message (like above)

Thanks for the quick response Bart, I think though I may need to explain a little more.

It's not as much an issue of getting the audio out, in fact I think it might all be working well enough for the needs. I will look at modifying an old sip phone i have around here too.

Is there any way of playing a wave file at the hangup of the originating call?

Using the call file method would allow you to send the message to the PA (amplifier) Sip Phone after the caller hangs up. You need to write some code - but there are plenty of examples

So,

Algo which has great tools is making an announcement at Asricon --

Also, at one time there was a post here by the late John Mullinix on a tool for this. You called in, and had couple of options to record / playback, start over or finish. When you finished it would create and submit a call file to send the page over the intercom. Don't know if that script survived the great crash, or if anyone here might still have a copy.

Even though John Mullinix has passed away, his legacy of helping users remains. Here is the post for the delayed paging and I have copied the initial code below:

I have had customers that would like to have delayed paging. This cuts down on the feedback if the extension creating the page is near a paging speaker. Here is the code. Both extensions are in the from-internal-custom context.

I was just going to dig into my code snippets to find John's code above, when I saw kenn10 beat me to it. I have used it basically as is, just changing extension numbers to more closely match my system. I used a Grandstream phone set to auto-answer and had a line level audio cable plugged in to the headset jack. WAY cheaper than any other alternative I have found. Worked swimmingly
