Hi mate
You probably got a same experience with big Telco's...they reading from script and anything outside that - they don't know what you talking about...their checklist - you have signal, phone ring and you can make call - case closed...but how to overcome 15 seconds of silence and then reorder tone after call is completed?
It's called disconnect supervision. The telco is supposed to send a voltage reversal that tells the phone system to hang up. Some places call it quick disconnect or whatever. If you can't get it solved it I would suggest making the AA time out to hang up. Just make it so they have to dial 0 or something t leave a message. This has the added benefit or getting rid of robo calls.
If I can get them to activate polarity reversal - case closed - but here in AU Telstra has discontinued use of that service years ago and they not have intention to bring back on IAD (don't ask why...) - even is only one tick on IAD settings...
Just for our American posters, Telstra, the main carrier in Australia use Cisco SP8000 ATAs to deliver some analogue services over SIP. The problem is that by default, the cleardown tones are set to the american default but the Australian cleardown tones are different. Problem is, Telstra don't normally change the settings unless pushed! This results in one call circulating round the voicemail and ring group until the mailbox is full! The link takes people to an extract from a Telstra document that details the issue and gives the correct settings needed. The tough part is getting past the level 1 support to level 2 who can make the changes needed (as with most big Telcos)!
Edited to add that 14-02-18 also needs to be checked for this to work!
