[asterisk-users] Hangup cause 111 after call pickup

[Jonas Kellens]

Hello,

when picking up an incoming call from one ip phone on another ip phone, 
the call terminates after about 5 to 10 seconds.

When reading out the hangup cause variable in the h-extention of the 
dialplan, the hangup cause seems to be 111.


In the dialplan output, you can see that SIP-peer sipacc3 picks up the 
incoming channel SipAgenT01-00001454, and the call is answered. After 7 
seconds, the conversation is terminated.

/[Jun  6 10:13:15] VERBOSE[21118] pbx.c: [Jun  6 10:13:15] -- Executing 
[120 at sub-pickup:25] Pickup("SIP///sipacc//3-0000147c", 
"SIP/SipAgenT01-00001454 at PICKUPMARK") in new stack//
//[Jun  6 10:13:15] VERBOSE[20788] app_queue.c: [Jun  6 10:13:15]     --

Executing [h at pbx-routing:3] NoOp("SIP/SipAgenT01-00001454", "hangup 
cause = 111") in new stack/



Questions :

1. what can cause a hangup cause 111 ? What is the meaning of hangup 
cause 111 ?

2. on voip-info.org I read "/111 protocol error 500 Server internal 
error/". How can I fix this ?? Using Asterisk 1.8.12.2 on CentOS.



Kind regards,

Jonas.
