[asterisk-users] Telco is not detecting HangUp w/ TDM400P

[Alex Pankratov]

Thanks, Julian. 

I saw this explanation, and it does not apply. There is no 
"hangup supervision" with my carrier. I think they used to 
have it, when I had different number, but even then it was 
not 30 seconds, but more like 3 to 5.

I am now inclined to think that it has something to do with
a cell phone provider. I am going to run more tests today 
using regular land line and report what's up.
