In Asterisk I have implemented realm-based authentication so that we can pick a set of credentials based on the realm in the challenge.On 17 September 2013 21:59, Olle E. Johansson <oej@edvina.net> wrote:
In theory a SIP request can have multiple proxy authentications and one www authentication. In practise very few phones support it.
Interesting that in my testing / experiments I saw Bria do this correctly. I had both Kamailio and my final destination authenticate Bria's invite. I used different realms and Bria dutifully answered both and offered the final invite with both authentications included.
Early SNOM firmware did this right, but they have removed it since.I did wonder whether other clients were likely to do it right. (And I did "fix" the double authentication in the meantime)
