Re: [OpenSIPS-Users] OpenSIPS + Ekiga + Linphone: Could not send message: Forbidden

[Alexander Shukaev]

You are the Bo$$, Jeff. Exactly, that was the case. Although the data for the user registration was correct in Ekiga (and I also have no idea how the registration even passed), I decided to simply deregister and register again. As a result, I can now call from Ekiga to Linphone too, but there is a still a problem with IM, a different one though. Now Ekiga reports "NOTICE: Could not send message: Unauthorised" for IMs, and now I also understand why (thanks to your previous response): it does not send "Proxy-Authorization" anymore (see the attachment)! I begin to think that Ekiga is merely bugged, though I've heard lots of positive reviews on it, including facts that it can be considered a mature piece of software. So I still hope that this could be my misconfiguration on the OpenSIPS side and if anybody can point me to it, I'd be very grateful. Otherwise, I guess I better off with another softphone client anyway.

Kind regards,
Alexander

Alexander,

First, let me say I do not use Opensips for instant message or related
operations.  Looking at your capture, however, I may have a thought.
Let's look at the headers from Ekiga's authenticated MESSAGE:

U 2015/10/31 13:02:54.844064 192.168.2.109:5060 [1] ->
127.0.0.1:5060 [2]

MESSAGE sip:5678@127.0.0.1 SIP/2.0.

CSeq: 17 MESSAGE.

Call-ID: 868b94e5-5e7e-e511-8953-0008cafa0605@G75VW.

uri="sip:5678@127.0.0.1", algorithm=MD5,

Expires: 5000.

Content-Length: 2.

Max-Forwards: 70.

The From header says your Ekiga is configured with 5678, but you're
trying to authenticate as 1234 (Proxy-Authorization header).  I
believe that is why Opensips returns a 403 Forbidden Auth ID in the
subsequent packet.  You probably want 1234 in the From header since it
appears you're trying to send the message to 5678.  Perhaps this is a
misplaced value in Ekiga's configuration.  I'm surprised you're able
to completely a registration.

Or, I could be completely wrong.  As I mentioned, I don't do IM over
SIP.

Apologies, I don't want to look like a nasty bumper here, but I
can't believe that nobody has a slightest idea how to approach the

Hello everyone,

I'm testing a new setup of OpenSIPS. I have created two accounts
in
DB: 1234 and 5678. I run both, Ekiga and Linphone, to test
communication between these two accounts. So through Ekiga, I
register 1234 and add 5678 to contacts, while through Linphone, I
register 5678 and add 1234 to contacts.

There are two problems that I experience. First of all, within
Linphone I can do both, IM and call from 5678 to 1234 (Ekiga), and
in
Ekiga I can read those IMs and accept calls accordingly, while
within
Ekiga I can neither IM nor call from 1234 to 5678 (Linphone) as
for
IMs I get "NOTICE: Could not send message: Forbidden" (for calls I
assume it's the same error, though not shown). I attach the
corresponding Wireshark log. Secondly, even though I can IM from
Linphone to Ekiga, the result is strange. In particular, each IM
arrives twice to Ekiga. In other words, in Linphone I see the IM
being typed once into chat, while in Ekiga I get two notifications
for
each IM and that each IM appears two times in the chat.

I'm new to OpenSIPS and VoIP in general, and I have no idea how to
deal with these quirks. Any help is greatly appreciated. Thanks
in
advance.

Regards,
Alexander
