[asterisk-users] Problems with pickupgroup/callgroup with Asterisk 1.8.4.2

[Sebastian Arcus]

I have problems using the call pickup under Asterisk 1.8.4.2. I have 
another Asterisk with 1.6 - and it is working fine with the same settings.

I have setup the same callgroup and pickupgroup for all extensions in 
sip.conf - just to make things simple for testing. The sequence *8 seems 
to be completely ignored by Asterisk - the client shows "Call answered" 
when dialing *8 while the other phones keep on ringing (both software 
and hard phone clients) - but I see nothing in the Asterisk console. 
It's like the "*8" sequence skips Asterisk and goes through the iax 
trunks straight upstream to the trunks provider. Then weird messages 
show up in the console about "Max retries exceeded to host", I can't use 
our IAX outgoing trunks and the only way to get things working again is 
to restart Asterisk.

Am I missing something silly here?


Here is my sip.conf:

[general]

subscribecontext=sip-blf

context=default
disallow=all
allow=alaw
allow=ulaw
allowguest=no
tcpenable=no
tlsenable=no

tos_audio=ef                   ; Sets TOS for RTP audio packets.

canreinvite=no

dtmfmode = rfc2833

pickupgroup=1

[21](basic-phone)
secret=mypassword

[22](basic-phone)
secret=mypassword

[200](basic-phone)
secret=mypassword


And here is a trace of a call coming in through the IAX trunk, ringing 
internal sip phones 21 and 22, while I try to pick it up from 200:
