here is the scenario:
I am using kamailio as a sipserver. now I am trying to define a trunk gw to
interface to another sipserver. I need to Register to this second sipserver and
kamailio cannot do that since I would need it to act like a b2bua and handle
401 among other things. so I thought I use sems to fullfill the following
scenario:
kamailio sems external sipserver
Register
----------> Register
---------->
401
<---------------------------
Register with credential
---------->
200 OK
<---------------------------
200 OK
<--------------
if sems acts as a sbc, it should be able to pass anything through, should it
not?
Thanks

I thought, you want SEMS to register on some server. I don't think SEMS is able
to be a Registrar server.
Why don''t you use your opensips as an registrar server?

This seems to be related to the problem I had with sbc, which I tried to
formulate yesterday in a message to this forum.
I reported:
running sems in sbc mode, when a Register is forwarded to the sems I get a 501.
the debug shows
[#b6d79b70/15299] [onOoDRequest, AmApi.cpp:104] ERROR: sorry, we don't support
beginning a new session with a 'REGISTER' message
any idea what I am doing wrong?
I appreciate your help,
Thanks

Hi,
You may use reg_agent module for registrations at SIP registrar and terminate
calls from it. And yes, sbc module allows to proxy media through SEMS. As for
2.1 and 2.2 you'll have to think about mapping (both for app_mapping and sbc
profile mapping).

Hi
can i use sems as:
1. media proxy
2. register to other sip server
i want to do like this:
1.
caller and called register to opensips
clients --register--opensips
caller ---INVITE---opensips---INVITE--SBCmodule(SEMS)--INVITE--opensips
-----called
so the rtp from caller and called will go to SEMS
2.
client -- opensips --- SEMS(register) --- service provider
2.1
caller --service provider ---SEMS ---opensips---called
2.2
caller ---opensips ---SEMS --service provider---called
opensips and sems run in same server and have 1 NIC
opensips run in port 5060
sems will be run in port 5080
Thank you
Ha`
