UK PSTN number to IAX termination

Your service provider is restricting you from dialling 0844 UK numbers from abroad......

Dean

I have people in the UK who I'd like to be able to connect to my Asterisk box, so I signed up for an 844 number. Perhaps that was not correct.

My test case (a coworker) says that the number was "engaged" when he called it.

If somebody over there wants to try it, it's (0) 844-484-4891. I tried it from here and got "number not in service" when dialed via SBC (my PSTN long distance.) Also couldn't connect to it via voipjet.

Anybody know why?

Also, Could somebody please explain to this "yank" what the various prefixes mean: 870, 844, etc?

Thanks,

Hi,

I've found that my 0844 number can only be dialled from the UK. I've tried dialling it myself from Belgium and am told (guessing from my poor translation of French and Dutch) that this number does not exist.

However, friends dialling it from the UK have no problems. I have set it up to forward to my work number during the day and my home number during the evening... and receive calls no problem. It even forwards to FWD no problem.

I suspect the reason your 0844/0870 numbers are not working from the US is because your telephone provider does not support/know that number for the UK (I think Dean or Tjardick mentioned this earlier in this post).

The differences between the 0844/0870 numbers are the call rate charges and where they can be forwarded to and what times they can be called. The 0844 number cannot be forwarded to mobile phone numbers and to certain countries... it also only costs the caller 5p per minute. I think the 0870 is less restrictive, but costs the caller more (but I can't honestly remember if that is strictly the case as I've only got an 0844 number!)

Regards

George
p.s. Dean/Tjardick, maybe it is worthwhile having a separate page with the differences on the numbers - that way it would save having to direct users to the 'request number' page to find out? Just and idea...

FireFury :

Are there any authentication credentials provided by voipuser.co.uk when it makes an IAX2 connection so my PBX can be sure that it is really voipuser.co.uk making the connection? (Since I want to add more trust for calls from voipuser.co.uk than random calls from anywhere on the internet - e.g. I trust callerID from voipuser but not from other IAX2 connections).

I agree. Posting an RSA key to your site that we all could copy to our /var/lib/asterisk/keys/ directory would be great & highly advised. One very short extra line in iax.conf & we're golden.

Thanks so much for this service.

Hi,

keys would be better, but at the moment if you have a password in the iax2 address, doesn't that prove that the calls are coming from voipuser.co.uk?

Looking into that now....

What are you trying to do?

I have this idea that I can use Asterisk to run a small number (normally 2) of VoIP devices over my ADSL connection, and provide limited access to an experimental IVR for incoming callers (probably no more than 2 simultaneous connections). From what I have read so far IAX seems to be a good way to do this.

Richard

Yep! - Asterisk does that nicely.

I would be interested in connecting via IAX2. I am hoping that this will solve some problems I am having with SIP connection via certain types of ADSL modem/router, particularly the later versions of Speedtouch 510.

Can ome kind soul point me in the right direction with configuring my Asterisk to accept IAX calls from VoIPUser!?

What config files do I need to edit, and what do I point VoIP user to!?

I have a domain name pointing to my asterisk box
I have tried using default<at>mydomain.com, and asterisk rejects the call "chan_iax2.c:5441 socket_read: Rejected connect attempt from 213.166.5.129"
This is I guess, because I haven't defined it anywhere!

Help!

Ta!

You need to create contexts in iax.conf and extensions.conf

Asterisk Configuration for IAX Termination of VoIP User No's is the post to read. Exercise a little care, the context names used are the same as the ones used for SIP termination. They need to be unique.

Excelent!

Works a treat!

One other question,
Can I make calls with IAX through VoIPUser?

I currently have a SIP account, with a different telephone number, but would prefer to make outgoing calls presenting the other number.

Sadly outbound IAX isn't available... yet?
