[Linphone-developers] Linphone & registration

[Ivica Babarovic]

Hello!

I'm using SER SIP server. I connect to it with a windows
Windows Messenger client and a Linux Linphone client.
I managed to somehow force Linphone to register to the server.
This was done by my friend by tweaking a code a bit.
What I would like, is to see my linphone client in the contacts
window of a messenger as active.
If I connect to the SER server with two Win. Messengers they can see
each other.
Also, if I call directly from Linphone to Messenger I manage to
establish a VoIP link. But I would like this to work over a SER server,
so windows client can call Linphone and vice versa. But in order to do
that it
needs to know that a Linphone client is on. So I think (IMHO) that
Linphone is
not registering itself correctly at the server side.

Here is a short description of my setup.
Machines:
Lilija = SIP server (Linux)
Raindrop = windows client (messenger)
Emsy-Lj = another windows client (messenger)
Winphony = linux client (linphone)

1.)When I register to the SIP server with
Messenger I get two packets on the port 5060
on the Linux server (Lilija):

address@hidden root]# ngrep  *@  port 5060

Notice how SIP Methods are reported on registration (first packet).
(methods="INVITE, MESSAGE, ...)

2.)If I register with Linphone I get the following two packets.:

address@hidden root]# ngrep  *@  port 5060

Here you can see that SIP methods are not registered.
I wonder if this functionality is included in Linphone.
And of course if this is really the problem.
I only asume that messenger is not seeing Linphone couse of methods.
I'm maybe wrong.


So my questions are:
What is the status with registration code in Linphone. Where do I start?
What should I do?
Is Linphone totaly SIP compliant (as far as methods are concerned)?
And if not, what method should I report with Linphone so Messenger
can see it and start a conversation and of course vice versa.

I hope I was clear enuogh on my problem.

I'm using libosip-0.8.8, linphone-0.9.0
