How to remove digest authentication from SIP trunk 1

[mic501]

Hello guys..
I have a SIP provider which is not allowing me to place calls because they want me to REMOVE the "Digest Authentication" message from the INVITE.
I don't seem to be able to find the right tick on the SIP form to be able to do this.
Are there any experts that know which tick box is the one?

They are referring to this message in the INVITE:

Authorization: Digest username="2215707000",realm="trunk.tel.com",nonce="BroadWorksXk558x2bjTffit39BW",response="16dcd344c49977261644f4ced30261",uri="sip:2293883@trunk.tel.com",algorithm=MD5,qop=auth,nc=00000010,cnonce="d

I think this is the Cache Auth Credentials on the SIP Advanced tab, but may be wrong. Never had a provider ask this before. Try turning this off and retest.


Cache Auth Credentials Default = On.
When set to On, allows the credentials challenge and response from a registration transaction to be automatically inserted into later SIP messages without waiting for a subsequent challenge.

I did see it disappear from the trace..thank you very much for the fast tip!
Even though I am still getting a forbidden message from the provider, so I have to see what needs to be tweaked... it's a new provider..and therefore new rules!

Does the provider expect registration? Or authenticate by the public IP?

I sorted this one out.
As you may understand some providers dictate their requirements and we have to meet them.
They didn't like the authorization digest with every call placed, so thanks to IPOLackey the setting is right. I noticed that it went off the trace.
Then the provider asked me to show the P-Preferred-Identity. I am running on version 9.1 and this parm is not available. Therefore I pretended to show the PPI
by using the "From" field and the call went tru.
In version 10.x and later the PPI can be customized, unlike earlier versions.
