SIP Authorization header modification failed

[sameul.mumbere]

I have been setting up CUBE to register with a service provider. The provider expects:

Digest username="+25675440000@provider.com",.........

but CUBE is sending this:

Authorization: Digest username="+25675440000",realm="provider.com",uri="sip:provider:5060",response="17c1db1cf80b0c4c0252ada3745d4130",nonce="UQn9BVDZqPnER5PeQl8IfQ==",cnonce="FFFFFFFF",qop=auth,algorithm=MD5,nc=00000001

However when I modify the sip profile as below; It affects all values that have "" (quatations)

request REGISTER sip-header Authorization modify "Digest username=\"+25675440000\"" "Digest username=\"+25675440000@provider.com\""

the result is:

Authorization: Digest username="+25675440000@provider.com",qop=auth,algorithm=MD5,nc=00000001

When i run it as just below; it remains unchanged;

request REGISTER sip-header Authorization modify "+25675440000" "+25675440000@provider.com"

Kindly advise how I can modify just the Digest username field. Am really new to this. Thank you.

Why does your ITSP need "+25675440000@provider.com" ? What is the username that they have provided for registration that you have added to sip-ua on CUBE ? Can you show the "401" challenge coming from the ITSP ?

Hi Nipun,

The username provided is +25675440000

But he needs +25675440000@provider.com in the Authorization header

You can have the username/credential configuration under sip-ua as "+25675440000@provider.com". See if it helps.

I have tried this but it affects the To, From and contact headers of the REGISTER message sent to the provider

The display becomes <sip:+25675440000@provider.com@provider.com>

This is not recognized by the provider

[R0g22]

That's right. That is why my first question was why does your ITSP need it this way. Who is the ITSP ? CenturyLink/Level 3 ?
I can check if a SIP Profile can achieve it. I doubt. Else you can keep the sip-ua that I suggested and use a SIP Profile to modify the To, From and Contact headers.

Hello @sameul.mumbere  @R0g22 

I have the same problem.

Could you solve the problem? did you modify the Digest username field?

[TONY SMITH]

Can you post up your current sip-ua configuration, and your outbound Register and other messages where you need to modify the username?   I expect a SIP profile could do the trick but there may be better ways.

Really what we want to see is what you're actually sending, and a description of what your ITSP says you should be sending.

Hello @TONY SMITH 

Thanks for your reply, but I got the solution to my case:

I was useing this config normaly:

sip-ua

credentials username 123@test.com password 123456 realm test.com

and I changed with this:

credentials number 123456 username 123456@test.com password 123456 realm test.com
