Hi guys

I am trying to setup 2talk sip trunking with my FreePBX (stable - 10.13.66, FreePBX13, asterisk 13)

Here is my peer details:

type=friend
username=my_number
fromuser=my_number
secret=my_password
host=sip.2talk.co.nz
context=default
dtmfmode=rfc2833
disallow=all
allow=ilbc&gsm&alaw&ulaw
nat=yes
canreinvite=no
insecure=invite,port

User details:
[empty]

in asterisk cli, i got this:
chan_sip.c:23771 handle_response_register: Forbidden - wrong password on authentication for REGISTER for 'my_number' to 'sip.2talk.co.nz'

I have checked my password and number, they are correct, any idea??

Thanks guys

James

Try changing the port that you register to from 5060 to 50600 (I don't have the specific line for your peer definition to offer you, but I'm confident that some googling will find the answer for you fairly quickly).

The reason for the change is to avoid any SIP ALG that may be present in the NAT engine in your router. Broken SIP ALGs can frequently easily disrupt registrations and 2talk listen on 50600 in addition to 5060 specifically for this type of work-around.

Hope this helps :)

I'm pretty sure that I had a case where I couldn't register to 2talk (My internet was up and down all over the place) - so I had assumed that I'd locked up the 2talk registration. I simply turned off the asterisk box and turned it back on again 10 minutes later (the theory being that the registration would settle down after that)

My setup is very similar to yours - I have "qualify=yes" and allow set to "ulaw,alaw" as the differences.

This won't help registering..
But take out ilbc & gsm codes and add g722. Also disable g729 in 2talk portal.
Context should be 'from-trunk'.
And depending on your router a qualify entry may be helpful for nat issues.
Also, generally for a trunk using normal SIP registration type=peer is sufficient.

But I think the error is quite clear, bad Auth. So check your registration string is correct and your details are correct.
May be worth simply testing your credentials with a soft phone (or some other sip client), microsip is perfect for this.

OK, I have changed my codec to alaw, ulaw and g722, and my sip port to 50600. I still get the same message.

It looks like something to do with my router settings. I can make external calls, but I can't receive external calls. My router is SonicWALL.

My firewall allows sip.2talk.co.nz to my external IP address (tried VOIP service only, and all service)

My NAT policy translate the destination of sip.2talk.co.nz to my server LAN IP address ( tried VOIP service only, and all service)

What else did I miss??

Hi guys

I have changed my peer details to follows:

type=peer
username=MyNumber
fromuser=MyNumber
secret=MyPasswd
host=sip.2talk.co.nz
context=from-trunk
dtmfmode=rfc2833
disallow=all
allow=alaw&ulaw&G722
nat=yes
canreinvite=no
insecure=invite,port

[user content] & [user details] are empty

MyNumber:MyPasswd@sip.2talk.co.nz/MyNumber

I have checked my firewall & NAT policies (I even get someone else to have a look for me), I have check my account name and password.

I still get this message:
[2016-05-06 12:47:14] WARNING[1837]: chan_sip.c:23771 handle_response_register: Forbidden - wrong password on authentication for REGISTER for '02825562245' to 'sip.2talk.co.nz'

I have tested with a softphone, I can call external line and received external call. No problem at all.

When I tested with FreePBX, I can only call external line, but I can't receive external call.

Any ideas?

Cheers

James

jms042016:

My router is SonicWALL.

Could well be this causing it. If anybody asked me to deploy a VoIP system using Sonicwall gear I'd tell them to buy new hardware for a start. The SIP transformations are terrible.

Hahaha SonicWall.... run for the hills!!! Ive never had a good time with sip and SonicWalls.

Go through and make sure any ALGs are turned off. Perhaps also add firewall rules to accept all traffic from 2talk.

Then probably not a bad idea to add something like 'qualify=120' to help with keeping the nat state active. Also maybe play around with the 'nat=' line. Might help actually using nat=never on the off chance the sonicwall is actually nat'ing properly.

Anyone using IAX2 instead of SIP?

Edit: I did mean version 2 :-)

IAX2 is fine and never given problems for me when I've used it a long time ago in a business situation with 2talk. It would certainly get around the SIP ALG issues the sonicwall have.

You can make sonicwall's behave - they just have hidden pages to make things work properly though I do agree with previous sentiments - anytime I've had to make SIP work with sonicwall I sigh.

Can you bypass the Sonicwall to troubleshoot. I.E. Get it work through a plain router first, then reintroduce the Sonic.

Thanks guys for all your help, I still can't get it working myself. So I get someone knows more about router/networking than me to have a look. And he fixed it for me, now it's working.

He said it could be conflicting NAT policies. eg A policy over write another policy.

I have updated my peers details as some of you suggested, thanks a lot!

Not sure if it's relevant, but when I set up 2talk at home last I found that the default 4 digit pin assigned by 2talk didn't authenticate until I replaced it with my own 4 digit pin. It might pay to try changing any default 2talk passwords in your setup.
