Hi

I am trying to set up a SIP register trunk for outgoing calls with the service "Call With Us". However I follow the instructions given by them and I get the following error from PBXnSIP service:

403 Forbidden (Bad auth) (Registration failed, retry after 60 seconds)


The info that my provider gave me is:

SIP/IAX client configuration
Different SIP clients (hardware SIP phones, ATAs and software ones) have different configuration screens, but all have a common set of configuration parameters. In the table below, username and password are your 9-digit long login name and 6-digit long password you received in the sign-up confirmation e-mail.
Configuration parameter Value
SIP server (or proxy, or domain) sip.callwithus.com or uk.callwithus.com if you are in Europe, Africa or Middle East.
SIP proxy (or "Outbound Proxy") leave blank
STUN server stun.callwithus.com, port 3478
Username (or User ID) username
Password password
Auth name (or Auth ID) username
Display Name (used for callerId information when you place a call) Your name
Register (or Send registration request) Yes
Register Expiry (or ReRegistration interval) 120 sec (2 minutes)
Silence suppression (or Voice Activity Detection) On
Use DNS SRV Yes

How should be this information set up in the "options" that PBXnSIP gives?:

Name:
Type:
Direction
Display Name:
Account:
Domain:
Username:
Password:
Password (repeat):
Outbound Proxy:
CO Lines:
Dialog Permissions:
Codec Preference:
Proposed Duration (s):
Keepalive Time:
Send email on status change: yesno
Strict RTP Routing: yesno
Avoid RFC4122 (UUID): yesno
Accept Redirect: yesno
Interpret SIP URI always as telephone number: yesno

Thanks.

Type: SIP Registration
Direction : inbound and outbound
Display Name: username
Account: username
Domain: sip.callwithus.com (depending on where you are)
Username: username
Password: password
Password (repeat): password
Outbound Proxy: sip.callwithus.com (depending on where you are)

Trunk ANI : caller id that you want the outsiders see

Solved;

The trunk now is registered successfully. I created a very simple dialplan just to test the service:

PREF TRUNK PATTERN REPLACEMENT

100 Unassigned
100 CallWithUs 00*


But whenever I dial on my phone: 00<whatever> I just get busy tone. I tryied to look for some monitorin tool in the PBXnSIP web interface to see what is going on but I didn't find anything. With a soft SIP phone the calls are working.

Any idea?

By the way, thanks for your fast and effective support!

What replacement are you using? Maybe also use 00* as replacement. Otherwise the PBX will cut off the first two zeros and then I can understand the carrier rejects the call.

My SIP provider is expecting the following structure:

[CountryCode][phonenumber]

I made some changes so now the users should use the prefix '1' in order to place long distance calls.

So if somebody wants to call for instance to Spain (+ 34 956606060) must dial on the phone: 134956606060, but my SIP provider is only expecting 34956606060, so my dial plan will be:

Pref: 100
Trunk: CallWithUs
Pattern: 1*
Replacement: *

I tryed this but I am still getting the busy tone (if the problem was a bad number string compossition, I would get an "air" noise, as my provider says, so I am afraid that the Trunk is not even connecting to CallwithUs, but it is registered).

Thanks.

That looks okay to me...

Can you turn SIP logging on and show the INVITE packet that is sent to the provider and the response which is sent back?

This is what I find after trying to place a call:

I think we need to take a look at the SIP packets in detail, see http://wiki.pbxnsip.com/index.php/Log_Setup#SIP_Logging on how to turn that logging on. Maybe just use the watch list to see the traffic between the provider and the PBX (put 38.99.70.46 there).

I enabled the SIP login with as follows:

Log REGISTER: No
Log SUBSCRIBE/NOTIFY: No
Log OPTIONS: No
Log Other Messages (e.g. INVITE): Yes
Log Watch List (IP): 77.68.40.174
Log Watch List: 9

The IP now is 77.68.40.174 because I changed the server for the trunk to another one (uk.callwithus.com instead of sip.callwithus.com).

Looking at the log file after trying to call I get:

Looks like '101' does not have any dial plan associated. You can do that either by going to domain setting or the extension setting to select the newly created dial plan

Does 101 have call redirection turned on??? You don't need a dial plan for calling in to a phone...

Solved.

The user 101 didn't have a dial plan associated because it was set to “Domain default”.

I thought that all the users in a certain domain are by default associated to all the dial plans that are defined in the domain. I have misunderstood the concept of dial plan in PBXnSIP and finally I associated 101 to the dial plan that contents routes to the SIP provider trunk. Now it is working fine.

I have been working a long time with Asterisk and my error is to think in “Asterisk way” when I am playing around with PBXnSIP!

Thank you very much for your support, I am very amused by such fast answers; this really makes worthy to have decided to go with your product!

Now I am going to investigate if PBXnSIP is easy to setup a FAX, but this is another issue for another thread...

Regards!

But whenever I punch on my phone: 00 I just get active tone. I tryied to attending for some monitorin apparatus in the PBXnSIP web interface to see what is traveling on but I didn't acquisition anything. With a bendable SIP buzz the calls are working. So if somebody wants to alarm for instance to Spain (+ 34 956606060) have to punch on the phone: 134956606060, but my SIP provider is alone assured 34956606060, so my punch plan will be,
