[Asterisk-Users] Flash zap trunk from Softphone or IP Handsets...

[Marc-andre Poupier]

Hi Guys!!

 

I wrote a little patch for asterisk 1.2.5 and I will maintain it for future release unless somebody explains me how we can ask people at Digium to add it to the source tree...

 

We are planning on using Asterisk as our main PBX for the office over the next few weeks.  Our current setup uses TDM400 cards to bring our 8 lines into Asterisk, our Telco provides us an option for three way calling and call transfer on the lines, option that we use extensively, we rarely do conf call between people that are in the office and often somebody will conf me on my cell from an office line and so on. Anyway to make a long story short we needed an option to flash the zap trunk from either a soft phone or an IP handset.  I looked at all the available workaround like transferring the call to an extension that would flash and transfer the call back to me, or I found on voip-info.org somebody using the features.conf to make an option such as *3 to flash, but the limitation with that procedure is you have to know who placed the call to use the correct feature call (like *3 would flash the caller and *4 would flash the callee, depending on whether you received the call or made it) which I found some what crazy.  So I added a detect context to features.conf which then finds which channel is the zap one and call the flash on the right channel for you.

 

So here what I have.

 

A patch that works on asterisk 1.2.5.

 

The patch is available here http://mail.guardianmicro.com/asterisk/map_flash.patch

(I put it up on my website just because I'm curious to see how many will even care of downloading it :-) )

 

My features.conf contain something like:

zapflash => **,detect,Flash,()

 

My Extensions.conf looks like this:

[globals]

DYNAMIC_FEATURES=>zapflash

 

[guardian]

[...]

exten => _9NXXNXXXXXX,1,Dial(Zap/1/${EXTEN:1},,wW)

 

[incoming]

exten => s,1,Answer()

exten => s,n,Wait(2)

exten => s,n,Dial(SIP/221,,wW)

exten => s,n,Playback(pls-wait-connect-call)

exten => s,n,Flash()

exten => s,n,SendDTMF(mycellphonenumberhere)

exten => s,n,Wait(5)

exten => s,n,Hangup()

[...]

 

So any of my users can press ** to flash the line from any SIP/IAX or else technology, the only pit fall would be somebody flashing from another Zap extension, but I could fix that as well if any body cares of such scenario...

 

Anyway if you plan on using it just drop me a line I would like to know about your experience with it.

 

Thanks!! Long life to Asterisk!!
