[OpenSIPS-Users] BYE - 404 not here

[Max Mühlbronner]

Hello everyone,

i have a problem when a call is hangup by the callee, i think i probably 
have some general routing logic Problem and i cant find any way to solve it.

caller --> asterisk (62.66.66.67) --> opensips(62.66.66.66) (+rtpproxy 
on the same machine) --> pstngw (213.20.11.11)
          
Everything seems to be working fine, i have been testing a long time 
but  i recognized some problem. When the callee rejects the call , (486 
busy) the busy is fine, transmitted back to the caller.
But if the call is established and the callee hangs up, the BYE is not 
received by the original calling side so it stays connected.
My opensips knowledge is still very basic, so please excuse if it is 
some dumb routing mistake made by me.

62.66.66.66 --> opensips
62.66.66.67 --> asterisk
213.20.11.11 --> pstngw


The busy is fine, and transmitted correctly (and callattempt is 
stopped), but the bye is not received on the side where the call was 
originating from (asterisk).

the not working BYE, followed by 404 not here, which is sent by the 
basic routing block (like in most of the example scripts / 
sl_send_reply("404","Not here");)
