Unable to transfer call using Dial method

Asterisk Asterisk Support
1

Hello.
My problem is as the title says that I cannot transfer calls to external numbers (mobile for example) using the Dial method (or make external calls whatsoever). I receive incoming calls without a problem. I have a working dialplan which plays a menu recording and by pressing 6 the caller should be able to be forwarded to an external number, which does not happen.
Here is the output I get from the Asterisk cgi
(I’ve changed the number which I dial to connect with Asterisk with card_number, the caller number to caller_number and the desired external number to external_number)

I have installed Asterisk 1.8.17.0 on a CentOS 5.8 system with an OpenVox B800p card. I am using DAHDI drivers and FreePBX ui.

Any help will be appreciaated :cry: :cry:

You got CALLS TEMPORARILY BARRED as a narrative error. You will have to ask the service provider whether that means at your end or at the destination end.

You are sending an NANP national format number but with type of number set to unknown. I would normally expect TON unknown to require the initial 1 (assuming US/Canada), if accepted at all.

Also note that the numbers have not been properly redacted.

Transfer implies redirection. You will only actually get relaying (tandem exchange).

Thank you for your answer! I should have mentioned that I am new to all this. I didn’t get more than half of what you wrote. :blush:

Can’t I find out somehow if it’s an error on my end or the provider’s end? I don’t know what I would say to them.

Were should I set the type of number? The server is located in Greece.

You mean that I failed to change the actual dialed numbers? I used the replace function of notepad++ before posting here.

What I want is to have a menu recorded and with the press of a button the caller to be able to talk to someone on a different city who has an ordinary phone without the caller hanging up and redialing. I don’t know if it’s called call transfer, call forwarding or tandem exchange. :blush:

I’m not used to reading ISDN traces, but it looks to me as though the central office has sent a custom error message, in plain text, rather than a coded error. That probably means that, unless you know what is being used by hte PTT, you cannot be sure what the error means. As such, it is probably best to get the PTT to tell you what that message means.

For type of number, see chan_dahdi.conf.sample, starting from “PRI Dialplan”.

If you are not in the North American Number Plan area, the rules for national numbers may differ from those in the US, and the national-number-dialed prefix is probably not 1.

Your caller ID has type of number set to national, and starts 210, for a total of 10 digits. Your outgoing number is given as of unknown type and starts 697, for a total of 10 digits. The length and initial digit suggests it is actually a national number. In the UK, one would expect such a number to be prefixed by 0, if not flagged as a national number. In the US, one would expect it to be prefixed by 1. I don’t know what the rules are for Greece. Some central office exchanges may guess the format from the number length.

Ordinary phone users must include the prefix, but ISDN, with a national number type, must not have the prefix.

The numbers are in the hex version of the signaling packets. Knowing the actual length of the number and the initial digit is probably important.

The other thing that could be going wrong here is that the central office could be rejecting the call completely because the caller ID doesn’t belong to you. Normally you would expect it to replace the caller ID with your own.
