[asterisk-users] intercom/paging with grandstream gxp2000

Thu Aug 7 11:27:45 CDT 2008

I added the configuration as you suggest but now the phone does not do
intercom. I tried Dial and Page in the gxp2000 but everything goes out as
Dial.

Here is the extensions.conf now
exten=s,1,SIPAddHeader(Alert-Info: <http://127.0.0.1>\;info=Family)
exten=s,2,GotoIf($["${SIP_HEADER(Call-Info)}"="answer-after=0"]?3:4)
exten=s,3,SIPAddHeader(Call-Info: answer-after=0)
exten=s,4,Dial(${ARG2},20)
exten=s,5,Goto(s-${DIALSTATUS},1)
exten=s-NOANSWER,1,Voicemail(${ARG1},u)
exten=s-NOANSWER,2,Goto(default,s,1)
exten=s-BUSY,1,Voicemail(${ARG1},b)
exten=s-BUSY,2,Goto(default,s,1)
exten=_s-.,1,Goto(s-NOANSWER,1)
exten=a,1,VoicemailMain(${ARG1})

Any idea? I am very bad on this asterisk thing, sorry guys.

if the sip header Call-Info has value answer-after=0 it goes to prio 2,
otherwise 3

Now let's have a closer look at those.
Hhmm, prio two is the gotoif, prio three adds the answer-after=0 ...

I think you mean:

exten=s,2,GotoIf($["${SIP_HEADER(Call-Info)}"="answer-after=0"]?3:4)
