asterisk users - Mar 2006 - Dumb question (hang up detection/Zapata.conf)

Another dumb question...

My asterisk system seems to have problems detecting hangups.  I am 
getting a LOT of voicemails with dialtone or silence.

I see over at asteriskguru.com there is an explanation of how to 
configure for polarity reversal in zapata.conf?

Does zapata.conf have any function in systems that aren't using zaptel( 
I suppose not)?

I am using an external gateway (wellgate 3701a) and don't have zaptel 
at all.

If I am not using zapata.conf (this is my guess) then is there some 
other way to configure this type of option for my FXO, or is this 
reliant on the devices setup?

Thanks,
marty

Just curious - what driver are you using?  (I'm not familiar with
wellgate.)

Could be dependent on device setup.  Quick question: what kind of
signaling are you using in zaptel.conf?  Did you happen to try
kewl_start?

I think your 3701a don't "understand" hangup tone (as our 3802 did
and
keep line busy after disconnect).

You need training the device. We had recorded the busy tone and
analyze with an audio editor (tone frequency and duration) and entered
the configuration via telnet interface (I think web interface is good
as well for this). And as a second chance we entered the values from
the suggested pdf in indications.conf:
