HI Alan,
sorry for the late reply - this week we have the OpenSIPS bootcamp and
I'm getting my hands on the emails only from time to time..
So, Are you loading the passwd in raw format (plain text) ? If so, you
need the calulcate_ha1 param to be set to 1
(http://www.opensips.org/html/docs/modules/1.5.x/auth.html#id228275) -
by default it is set to 0.... (see prev email)
Regards,
Bogdan
