Need help with extensions.conf/dialplan

Asterisk Asterisk Support
1

Ok so I’m having some difficulties dialing out. Soon as I press 1 digit it just goes to a fast busy.

Of note, Asterisk is setup as a 1to1 NAT behind a pfsense firewall, which handles all the NAT, in theory, which is why it’s disabled currently.

Here is my extensions.conf:

[from-trunk]
exten => s,1,Dial(SIP/301,15)
exten => s,2,Dial(SIP/1VoIP/mycellphonehere,15)
exten => s,3,Voicemail(${EXTEN})
exten => s,4,Hangup()

[internal]
exten => _XXXXXXXXXX,1,Dial(SIP/${EXTEN}@1VoIP)
exten => _XXXXXXXXXX,2,congestion()
exten => _XXXXXXXXXX,102,busy()

exten => _1XXXXXXXXXX,1,Dial(SIP/${EXTEN}@1VoIP)
exten => _1XXXXXXXXXX,2,congestion()
exten => _1XXXXXXXXXX,102,busy()

exten => _XXX,1,(SIP/${EXTEN})

and sip.conf, if needed

[general]

Console output of a failed call is really needed to tell what is going on.

I can point out that your final line of your Internal context is malformed and will not work.

Yeah I was trying to make it so if you dial 3 numbers it’ll ring that extension.

Here is my debug:

Why are you using such an old version of Asterisk?

I was hoping you would paste in the output from the Asterisk console as well showing the dialplan logic executing, Just the SIP debug doesn’t help here.

I will note you did try to just dial ‘1’ which does not match an extension in your ‘internal’ context.

5

As for the old version, it’s just what CentOS 6 comes with and I have it firewalled off and all where only the VoIP proxy has access to it.

On the console I have a verbosity of 5 enabled and it just says this soon as I dial 1:

== Using SIP RTP CoS mark 5

Do I just need a better dial plan? I just want it to dial external for 10 or 1+10 digits or ring an extension if 3 digits are pressed.

6

You are making the call in the internal context, but your extension 1 is in the from_trunk context. As such it requires a 10 digit number or an 11 digit number, given that it starts with 1.

7

Logs shows clearly the issue, as David also mentioned before there is no extension (1) on internal context

8

Ok sorry for my n00bness, but what is the easiest way to fix this?

9

Dial the complete number.

Look at your contexts, you don’t have any rule to handle just “1”.

Oh, well that’s part of the problem. It fast busies immediately after I dial 1, so I can’t even complete the number.

11

It is not clear what you are trying to do. If you want to just dial 1 from the phone, and have it connect to extension 1, you must include (either physically or with include ==>, extension 1 in the internal context.

If you actually want to dial 1XXXXXXXXXX from the phone, you should either make sure that the phone’s dialplan doesn’t consider 1 to be a complete number, or you should configure the phone to support overlap dialing (or replace it with one that does), so that it doesn’t fail the call when told that more digits are required, but simply tries longer and longer numbers.

Note that fast busy is coming from the phone, not from Asterisk.
