So I've got asterisk and the spa3102 PSTN working well together. Outoging phone calls from an asterisk extension go out through the SPA3102 PSTN line to telecom, and incoming calls from Telecom through the SPA3102 PSNT go to the asterisk extensions. Hangups and disconnects work fine.

But that voicemail! If the incoming telecom PSTN caller hangs up before voicemail engages, the call gets disconnected fine. But once voicemail kicks in... it hangs on to the line for at least 45 seconds after the caller hanges up. The SPA3102 PSTN line stays "offhook" for the duration. Can anyone shed some light on what may be the problem? I've googled and googled this but can't pinpoint the problem.

SIP settings...
[pstn-spa3102]
type = friend
auth = md5
host = dynamic
port = 5061
username = pstn-spa3102
secret = xxxxx
fromuser = pstn-spa3102
disallow = all
allow = alaw
allow = ulaw
dtmfmode = rfc2833
context = incoming
insecure = invite,port

SPA3102 PSTN line settings...

You need to have 'Clear forward & Answer Reversal' added to your line.

This is only an option on business lines. Last time I tried to get that added to a residential account they wouldn't do it. I am pretty sure that is the case with any provider and not just Telecom too.

I tried various PSTN silence detect settings, but they either diddn't disconnect the call or disconnected too aggressively.... but then SUCCESS.

Changing the Disconnect Tone setting on the SPA3102 to 425@-30,425@-30;2(.25/.25/.25/.25) as per the middle of this thread http://forum.voxilla.com/threads/disconnect-tone-tweaking-solution.2780/ works great. I previously had 400@-15;*5(.25/.25/1+2) which didn't work.
