Avaya IP-Office SIP line registration qop=auth parameter missing

[J.S.]

Hello, we noticed a bit of an incompatibility issue between a Avaya IP-Office PBX and the Core network.
When the user (IP-Office) tries to register, the S-CSCF rejects the registration request due to the missing QOP (quality of protection) parameter in the Authorization header.
Is here anybody who can help us to enable these parameter for authetication for the sip-line in the IP-Office?
Sw release 11.1.0.1.0 build 95

qop is missing from the IP-Office:

Authorization: Digest username="entrST210000000006",realm="entr.fixed.lab-vodafone.de",nonce="326f8fd961f144d22A14d27d8ec0b289ce5daf4ccbcda3119836d9",response="3ede7b5bf8bba9369cde448edaa18209",uri="sip:entr.fixed.lab-vodafone.de"

Quality of Protection is not a term I am familiar with and manager help finds no results for it. I did some searches on the google and I found a few Avaya documents with this term but mainly for Communication Manager/Aura. My guess is that IP Office does not support QOP. If anyone knows better please correct me.

The truth is just an excuse for lack of imagination.

I would ask Vodafone if there are other options.

I’ma little confused because I knew Vodafone (Germany) only without Registration…

IP Office remote service
IP Office certificate check
CLI based call blocking
SCN fallback over PSTN

It is a new Vodafone SIP trunking product with Registration. Maybe anyone else here in this Chat has knowledge about that topic? Are here maybe some Engineers from Avaya who Can help here? Thank you very much.
