[SR-Users] sipml5 register to kamailio IMS (Unauthorized - Challenging the UE)

[Serhat Guler]

Hi Daniel,

Thanks for your reply. I dug in a bit more and found out that the sipml5
doesn't calculate the digest correctly when AKAv1MD5 or v2 is selected as
default (have no idea why). So, I set the default authentication algorithm
as Digest MD5 and now I can register the UE.

Cheers,
Serhat
