Hi,
I have a few questions about SIP and SER - feel free to blast me if they've been asked and answered before - I have tried to find my answers. I'm fairly new to SIP but not to VOIP (I'm sorry, most of my life is spent with CCM). I've played with SIP a bit but not really indepth.
The Scenario:
I have a few SIP phones at home (mostly Cisco 7940s and ATAs etc) and I want to build a residential gateway that will allow me to do the following in terms of "external" stuff:
Route outgoing calls to particular proxies that require (usually) digest authentication (eg. iconnecthere for international dialing, fwd, etc) - the thing I don't get is the authentication side of things - ie. the phone won't know it needs to authenticate so the SIP proxy must provide this ...
Look here for a post from Jiri explaining why SER won't register with other proxies. The problem is indeed the authentication part: http://lists.iptel.org/pipermail/serusers/2003-January/000261.html
Kind regards,
