Hi folks,

I've this infrastructure:

|voip services| -- |*| -- |cme| -- |isdn|

the voip services are logged on my *, then forwarded to number 601 on 
cme. The isdn calls too are forwarded to 601. On cme I've a timeout X 
for call-forward noan (no answer) to a specific number on * (5901) that 
is my x-lite software client. If 5901 is unreacheable the call is 
forwarded to voicemail (always on *) --> u601

Tests:
- - for isdn calls all works great, even if X=30sec
- - for voip services: if X=20sec, and 5901 is unreacheable, all works 
fine; if X=30sec, I've a tear down without voicemail; if X=20sec, but 
5901 is logged in, I've a tear down after 7-8 sec on x-lite without 
wait 20sec+voicemail as configuration.

I think there's a problem with * timeouts. What could I do?

my extensions.conf:

exten => _59XX,1,Dial(SIP/${EXTEN},20,tTr)
exten => _59XX,2,Hangup
exten => 5901,1,Dial(SIP/5901,20,tTr)
exten => 5901,2,Voicemail(u601)
exten => 5901,3,Hangup

Any suggestion will be appreciated
Regards
Andrea

Maybe an example will be usefull:


voip services --> * (5600) --> cme (601) --> * (5901) --> *
(voicemail
u601)

voip services on sip.conf
- -------------------------

register => 530xxxx:test@sip.messagenet.it:5061/5600

[5600]
type=friend
host=192.168.17.10
dtmfmode=rfc2833
canreinvite=yes
context=myphones
qualify=yes

cme on sip.conf
- ---------------

[cme-pbx]
type=peer
canreinvite=no

[601]
type=friend
language=en
host=dynamic
dtmfmode=rfc2833

x-lite client (5901) on sip.conf
- --------------------------------

[5901]
type=friend
nat=yes
host=dynamic
dtmfmode=rfc2833
canreinvite=no
context=myphones
username=5901
secret=xxxxxx
auth=md5
qualify=yes
callerid="Me - mobile" <5901>

generic on extensions.conf
- --------------------------

[myphones]
include => cme-pbx
include => voice-mail
include => asterisk-in
......

voip service redirect on extensions.conf
- ----------------------------------------

[cme-pbx]
exten => _6XX,1,Dial(SIP/${EXTEN}@cme-pbx)
exten => _6XX,2,Hangup
exten => _5600,1,Dial(SIP/601,45)

x-lite (5901) on extensions.conf
- --------------------------------

exten => _59XX,1,Dial(SIP/${EXTEN},20,tTr)
exten => _59XX,2,Hangup
exten => 5901,1,Dial(SIP/5901,20,tTr)
exten => 5901,2,Voicemail(u601)
exten => 5901,3,Hangup

voicemail on extensions.conf
- ----------------------------

[voice-mail]
exten => 5699,1,VoicemailMain(${CALLERIDNUM})
exten => 5699,2,Wait(3)
exten => 5699,3,Hangup
exten => t,1,Playback(vm-goodbye)
exten => t,2,Hangup
exten => _56XX,1,Answer
exten => _56XX,2,Voicemail(u${EXTEN:1})
exten => _56XX,3,Hangup


that's all.
With this configuration:

1. with no answer after 20 sec. on cme, the voicemail works only if 
5901 is not logged in.
2. with no answer after 30 sec. on cme, the voicemail doesn't work.
I've tryed to modify '45' timeout on voip services redirection,
without
success.
Any suggestion will be appreciated.

Andrea
