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 ...
"Register" with external proxies so that (eg. FWD and iptel.org ) and so
that it knows to send calls to my FWD number to my proxy
server so that my proxy can route to my internal phones and/or send the call
on to whereever I may be.
I've read through the SER documentation and I can see how to rewrite URIs
but I was confused about how digest auth works with that.
Can I actually do the SER registering with other proxies? I realize this
really isn't the role of a SIP server. Is there a better way of doing this?
Have I really just missed the point somewhere along the line? (I'm quite
prepared to accept that I may have ..)
I've had a play with getting Asterisk to do this and got it to register etc,
but got a bit stuck with the whole media/codec side of things (and basically
gave up prematurely!) I just wanted to do some SIP things!
My idea with doing these things is to see if I can figure out a bit of a
"packaged" up version of SER for those of use who want to integrate things
like FWD/iptel.org etc into our "normal" telephony environment at home.
(Anyone know what the easiest way of getting an FXO port at home is?)

Hi Mathew,
I found your questions interesting.
I have following suggestions and you can try that and let us know if that
works.
You might register to other servers might be in this way.
.....
if( method="REGISTER" )
{
# do authentication and save location here
# plus append a leg
rewriteuri("sip:username:password@iptel.org");
append_branch("sip:username:password@fwd.pulver.com");
sl_send_reply("200","OK"); # not sure whether "200"
really forwards
the method
break;
}
With respect to building the residential gateway, you can find there are lot
in the SIP markets, http://audiocodes.com , mediatrix, Pulver's Phone patch
( http://pulverinnovations.com ) etc., . If you have have with a PC you can
build with a asterisk http://www.asterisk.org with a lot of other excellent
features.
Best Regards,
Kannaiyan

This does not do anything -- it sends a 200 for REGISTERs without doing

Can you guide how to register to other proxy servers with SER?

if you are interested in using multiple services, purchase a phone which
is able to do so.

That is not possible, mainly because SER can't respond to digest
challenges.

Look here for a post from Jiri explaining why SER won't register with
other proxies. The problem is indeed the authentication part:

i have submitted patches to ser permissions that allow you to define
trusted peers. ask your provider to switch to ser and use that
feature. then they don't need to authenticate your proxy.

So the provider has to use ser, has to use the "permissions" module and
has to put an entry in the file "permissions.allow". I think it's a nice
idea, but I doubt a provider like Vonage will do this.
I can think of the following solutions:
- Buy a phone with multiple lines and program the credentials in the phone
- Use Asterisk next to ser and have a prefix routed to asterisk.
Configure asterisk to register with the proxy.
I'm not sure, but maybe when a b2bua module is made ser could act as a
UAC and register with other proxies.

I've got a 7940 with 2 -> but I need about 4 (no I don't have a 7960 hanging
around). This isn't a scalable solution, especially when you don't want to
have to explain to the wife how to dial ...
- Use Asterisk next to ser and have a prefix routed to
asterisk.
Configure asterisk to register with the proxy.
Yeah, I've tried Asterisk - I got it to register and thought you beauty,
it'll solve my problems, but it just got in the way trying to do all the
media recoding etc - I want to use G.729 but it won't let me - some calls
worked, some wouldn't - very ugly.
I'm not sure, but maybe when a b2bua module is
made ser could act as a
UAC and register with other proxies.
I think this is quite important - running a SIP gateway for residential use
is going to be more and more common. I'd really like to see this bit happen
so that a Linux Gateway can be setup (maybe a modified version of one of the
firewall/mail server distribution ones) so that anyone can get a basic
machine, drop it on the network, plug some phones in and get in/out dial
working quickly.
Kind regards,
