[Solved] CLI output and operation are different

Asterisk Asterisk Dialplan

Hello, I have problem about pattern matching.

I can not call 801 and 802 bidirectionally, but I can call them all at 800.
Do you have any suggestions?

sip.conf

[801]
context=from_phone
type=friend
secret=XXX
canreinvite=no
host=dynamic
dtmfmode=rfc2833

[802]
context=from_phone
type=friend
secret=XXX
canreinvite=no
host=dynamic
dtmfmode=rfc2833

[803]
context=from_phone
type=friend
secret=XXX
canreinvite=no
host=dynamic
dtmfmode=rfc2833

extensions.conf

[from_phone]
exten => 800,1,Dial(SIP/801&SIP/802&SIP/803)
exten => 80Z,n,Dial(SIP/${EXTEN},30)
exten => _X.,n,Set(CALLERID(num)=XXXXXXXX)
exten => _X.,n,Dial(SIP/gw/${EXTEN})

Output of CLI
dialplan show 801@from_phone, and notification when calling from 801 to 802.

CLI> dialplan show 801@from_phone
[ Context 'from_phone' created by 'pbx_config' ]
  '_80Z' =>         2. Dial(SIP/${EXTEN},30)                      [extensions.conf:870]
  '_X.' =>          3. Set(CALLERID(num)=XXXXXXX)              [extensions.conf:871]
                    4. Dial(SIP/gw/${EXTEN})               [extensions.conf:872]

Your sip.conf doesn’t match the dialplan show output.

You don’t have a priority one for the pattern _80Z, assuming that the dialplan show output is correct, in relation to the the use of _.

Also:
type=friend is inadvisable, except in special cases (can lead to mis-operation and security breaches)

canreinvite is deprecated in favour of direct media (indicates a failure to code from first principles, but currently they are treated as synonyms).

Look closely at how you used n (next priority) in the dialplan.
80Z does not have a previous priority.

[from_phone]
exten => 800,1,Dial(SIP/801&SIP/802&SIP/803)
exten => 80Z,n,Dial(SIP/${EXTEN},30)
exten => _X.,n,Set(CALLERID(num)=XXXXXXXX)
exten => _X.,n,Dial(SIP/gw/${EXTEN})

I prefer same to avoid this kind of issue. I also start every pattern with NoOp() and a comment inside.

exten => 501,1,NoOp(test)
 same => n,NoOp(do something)
 same => n,HangUp()
exten => 502,1,NoOp(another one)
 same => n,NoOp(something else)
 same => n,HangUp()

Thanks a lot david551, poing

I fixed following points, and It seemed like it should be.

  • every extension has 1st priority
  • change type friend to peer
  • canreinvite replaced by dicretmedia(allow|deny)
  • use NoOp() comment

sip.conf example

[801]
context=from_phone
type=peer
secret=XXXX
host=dynamic
dtmfmode=rfc2833
directmediadeny=0.0.0.0/0
directmediaallow=192.168.X.X/24

extensions.conf

exten => 800,1,NoOp(Call all phones)
same => n,Dial(SIP/801&SIP/802&SIP/803)
same => n,HangUp()
exten => 80Z,1,NoOp(Call each phones)
same => n,Dial(SIP/${EXTEN},30)
same => n,HangUp()
exten => _X.,1,NoOp(OutsideLine)
same => n,Set(CALLERID(num)=XXXXXXXX)
same => n,Dial(SIP/gw/${EXTEN})
same => n,HangUp()
