[asterisk-users] line disconnected after 20 seconds no reply to our critical packet

[Thomas Winter]

Dear all,

I have from time to time problems with disconnect after exact 20 seconds.

I have these problems from time to time in LAN after using PickUP() with 1.2
I have these problems from time to time in WAN when the internet connection is 
not reliable with 1.4

Is there any way to fix it?

best regards
Thomas
