Vitalie these are my complete logs. 


I masked my public ip address and my iptel account. My "private" ip address is 192.168.1.9. 


Thank you for your help, 
Denis

Oggetto: Re: [Freeswitch-users] 401 Unauthorized in iptel external gateway 

BTW, can you post all 4 queries of one register attempt (1,2,3,4)? 




2012/2/26 Vitalie Colosov < vetali100 at gmail.com > 


Yes I was not sure if you was able to call from registered endpoint thru FS and also directly, or only directly. 
So FS does not create correct #3 query...? 
Probably as was suggested above, someone can investigate directly at your server. 
Or if anybody has better ideas... 






2012/2/26 Anita Hall < anita.hall at simmortel.com > 


Vitalie is right. I have seen similar logs. 

I am currently using localphone and rapidvox as SIP provider and both register Ok. 

This is my sip_profile http://wiki.freeswitch.org/wiki/Provider_Configuration:_Localphone.com 

I could look it up for you if you can give remote access to your machine and watch over screen or byobu. 

Alternatively, you could give me your account name and password. I will check if it works from my installation. I promise not to make any calls and you can change the password later :) 

regards, 
Anita

Sorry, i did not exposed well the problem... 


I was able to call iptel account directly without the gateway (so without registering to iptel). 


When i setup the gateway i see sofia trying continuosly to register to iptel without success. 
I see many 401 messages like this: 



1. FS->IPTEL Register 
2. IPTEL->FS Unauthorized 3. FS->IPTEL Register 
4. IPTEL->FS Unauthorized 
5. FS->IPTEL Register 
... 


After a while sofia stops trying to register and retries after 30 seconds and so on. 


Thank you for your help, 
Denid

Usually SIP registration goes like this: 


1. FS->IPEL Register 




2. IPTEL->FS Unauthorized 



3. FS->IPTEL Register (yes, again, with additional credentials) 
4. IPTEL->FS OK 


You say that you was able to call iptel successfully, so FS is registered. 
You just did not observed and did not provide SIP messages #3 and #4.

Hi to all. 


Today I installed freeswitch following the guide in Freeswitch book. 
I made successfully all the tests in the book... well all but one. 


When I tried to setup an external gateway on my iptel account, the registration process failed with 401 sip message. 


This is the sip trace:

I'm sure that user account and password are valid. 
I also tested (successfully) a call from my extension to my account at iptel.org . 
Registration to iptel.org using a sip phone with the same user works just fine. 


What's wrong? 


Thank you in advance for your help, 


Denis
