[asterisk-users] Occasional call from "asterisk"

Sat May 7 00:27:44 CDT 2011

Telco always says it is not their issue.

This is all over google, did you even check?  Did you check your options in
chan_dahdi.conf?

hanguponpolarityswitch=yes

I am not sure if that is your problem but it would be helpful to list the
things you have found, tested, and ruled out.

As for prepending a 9 for redial, I would say doing it in the [outbound]
dial context would be best practice.

For my installations, I have eliminated the need to "Dial 9 for an outside
line"  That goes back to the key systems where 9 got you an outside line.

I have also eliminated the need to dial 1 as well.  A good dialplan makes
these legacy, I still leave them there to avoid confusion.

For some clients that use TDM and VoIP, I may make 8 + number go over VoIP
and 9 + whatever go over TDM.

Default without the 8 or 9 is to go out over TDM or whatever the customer
wants, or TDM if they seem lost.

I don't give them too many decisions to make, just educate them on the
options programmed into the system.

Last thing, your dialplan looks too over engineered.  How about this and
fixing your callerID syntax?

[inbound]
exten => s,1,Answer
exten => s,n,Set(CALLERID(num),9${CALLERID(num)})
exten => s,n,Dial(SIP/504&SIP/506,5,tTgr)
exten => s,n,Dial(SIP/501&SIP/502&SIP/503&SIP/504&SIP/505&SIP/506,10,tTgr)
exten => s,n,Voicemail(499 at default,u)
exten => s,n,Hangup

Thanks,
Steve Totaro
