Hi Brian,<div><br></div><div>Did you find a solution to your problem? or at least got a working dial-plan for it? I have the same problem again as well and want to know what to do with the dial-plan to off-set the effect at least since Telco says it's not their issue.</div>

<br>
Now and then our SIP phones ring with "asterisk" showing as the caller-ID.<br>
Upon picking up the receiver, there is about five seconds of silence and<br>
then the channel is closed (hangup). Can anyone offer some insight? Here's<br>
relevant snippets from my extensions.conf and Master.csv log:<br>
<br>
This line shows up in Master.csv:<br>
<br>
"","","1-NOANSWER","inbound","","DAHDI/1-1","SIP/505-00000150","Dial","SIP/5<br>
01&SIP/502&SIP/503&SIP/504&SIP/505&SIP/506,10,tTgr","2011-04-07<br>
21:37:05","2011-04-07 21:37:16","2011-04-07<br>
21:37:21",16,5,"ANSWERED","DOCUMENTATION","1302212225.444",""<br>
<br>
Here's [inbound] from extensions.conf:<br>
[inbound]<br>
exten => s,1,Answer<br>
exten => s,n,Ringing<br>
exten => s,n,Set(CALLERID(num),9${CALLERID(num)})<br>
exten => s,n,Dial(SIP/504&SIP/506,5,tTgr)<br>
exten => s,n,Goto(1-${DIALSTATUS},1)<br>
exten => 1-ANSWER,1,Hangup<br>
exten =><br>
_1-.,1,Dial(SIP/501&SIP/502&SIP/503&SIP/504&SIP/505&SIP/506,10,tTgr)<br>
exten => _1-.,n,Goto(2-${DIALSTATUS},1)<br>
exten => 2-ANSWER,1,Hangup<br>
exten => _2-.,1,Voicemail(499@default,u)<br>
exten => _2-.,2,Hangup<br>
<br>
The idea is that first 504 and 506 ring, then if neither of them answer,<br>
everyone rings. Works great most of the time.<br>
<br>
I have a hunch that maybe this happens if the inbound caller hangs up while<br>
the first Dial() is ringing, but I would've expected to see the first Dial<br>
(to 504 and 506) show up in the Master.csv log, and it's not there. (The<br>
preceding line of the log is a call from almost an hour earlier). In that<br>
case though I'd expect to see "1-CANCEL" in the log instead. Perhaps if the<br>
caller happens to hang up right between the two Dial() commands?..<br>
<br>
As an aside, the Set(CALLERID...) bit doesn't work. The idea was to prepend<br>
a 9 so that a SIP user could use the "redial" feature of the phone's call<br>
log to return a missed call (automatically including the 9 for outside<br>
line). Unfortunately the 9 does not get prepended.<br>
<br>
Thanks in advance for any and all advice!<br>
