Oddly enough, I almost forgot to mention Lumicall is using the ha1b column. I also posted a query on the asterisk-users list
about support for ha1b
- would you know if that is something that still comes up in practice?
It is in the Kamailio schema, but I have not encountered a device
behaving that way in practice.
There are few devices, not remembering any at this
moment that use
user value in authentication header as being username@domain.
ha1 = MD5(username:realm:password)
ha1b = MD5(username@domain:realm:password)
I hope I remembered correctly the order, by you get the idea.
In Lumicall, it is explicitly configured in the phone settings:
authentication username = +41xxxxx(a)sip5060.net
and it sends that whole value to the SIP proxy in the auth header
To be clear, this was an administrative decision and not a
device-specific issue.
- instead of having a ha1b column (which is a hassle for sharing the
database with Asterisk or other systems that don't know ha1b), maybe it
is also useful to have an auth_user column or to have a flag in the
domains table to indicate that the user@domain convention is used for a
particular domain?
not sure it would be domain specific, but rather subscriber
specific and
even device -- eg., same user using a snom phone as well as lumicall.
You can update kamailio config file to use pv_auth_check(...) function
where you give the password as parameter -- it is up to you from where
you load it (e.g., using sqlops). Then based on format of the auth
username, you load the appropriate value. But again, I'm afraid you
would need both values stored anyhow, because same user can have many
devices with different behaviour.
- in other cases, do people expect this for
administrative reasons or
solely to support devices that are internally hard-wired to this behavior?
I guess it the past we met devices that had it hard-wired.
Cheers,
Daniel
