Hello Davy,
I have a similar Problem, the SIP-Account registers at the provider, but it won´t register on the PBX-Trunk Objekt.
Back to 13r3 SR12 and everything is fine again.

Hi,
could it be, that you have not imported V14 Licences ?
If you only upgrade the pbx without import the new V14 License File, no internal Portregistrations will be work. (I had the same issue) 
Best Regards,

No, the pbx is license rental licensed, all the telephones are registering.
It's only the sip that's not working. the logs are showing registration failure.

Hello,
Just got a phone call from our registrar.According to their logs he noticed a changed way of authenticating.
I asked for a test sip.
i will get back to this.

Hi Davy,
in case it's really an authentication issue it would be very interesting to see the 401 response of the registrar.
Could be they do offer authentication algorithm beyond traditional "MD5"?

Re: V14R1Final No more sip registration to our registrar
Hi all,
bad news regarding 14r1:
There is a bug in SIP stack of 14r1 that makes the authentication fail.
Not in every environment, but in some.
It fails if the SIP server sends a digest challenge with "algorithm=md5".
It works as expected if the SIP server sends a digest challenge with "algorithm=MD5".
The crucial point is the letter case.
Uppercase is accepted, while lowercase is NOT.
Reason for the code change was that new digest algorithms are about to come for SIP (RFC 8760) and we prepare our SIP stack for that.
There will be a fix in 14r1 SR1 for this problem.
Older versions (e.g. 13r3 do not have this problem).
We apologize for the inconvenience
