There is already finished a full signalling b2bua module. It will be

I'm sure it can if enough effort is put into it. The problem you face
is that Linksys made many false assumptions when they devised their
MOH scheme and now you have to work around all of them. First of all,
even putting aside the media relay I do not understand how they
imagined this would work with NAT (which is pretty much a given these
days). In order for their scheme to work all involved NAT boxes in the
path (in the absence of a media relay) would need to have async full
cone implementations, which are not the norm, on the contrary are
pretty rare. With a media relay, you need a pretty specialized one and
none of the ones I know can support what they do out of the box. So
the only answer is that their devices currently only work with no NAT
and no media relay involved.
Another false assumption is that the receiving endpoint would accept a
media stream coming from a source that was not negotiated in the
current session. Maybe the Linksys devices accept this and if you
restrict yourself to only using Linksys devices it'll work, but as
soon as you plan to use other devices as well, all bets are off.

The security issue is not one that is fixed by creating a walled
garden. Isolation won't prevent any of your users to attempt to steal
a conversation for a purpose or simply wreak havoc in the active
sessions

Hi,
Is your xlite taking the challenge it get from opensips to REGISTER again?

Hello,
i want to upload my presence-rules.xml to authorize or not authorize watchers.
when i upload the document to openxcap i get these error in my syslog:
can anybody help me to resolve the problems?
i think a big problem is that the server can not find the socket from opensips
in /var/run/opensips/socket. anybody know what can be the reason?

Hi Bogdan, I really wonder how will behave this b2bua module when having
parallel forking with PRACK requests (so CSeq is just incremented in some
early-dialogs).
I assume that b2bua module will depend, as many others, on dialog module,
which doens't handle the above case.

Hi
thats very big project., for that you need to study the system indepth both
Opensips and Asterisk
at this moment iam working on the same project but my concept is
Opensips -- Registrar and Proxy and hand NAT with rtpproxy
for this Opensips can handle as many as users depends on the hardware and
design of network
use Dispatcher to loadbalance across Asterisk PSTN Round Robin basis
If you can Route X amount of calls to * 1 and * 2 Y amount of calls
use LB modules.
2 Opensips ( for loadbalance registration) replicate
1 Mysql Server
3 Asterisk for PSTN / VoIP handling
Hope this helps to start with.

It is more of a plan to be able to handle growth while not having so many of
the usual growth pains that ultimately mean losing customers. We want to build
a scalable system, starting with just two boxes of around 50 users each.
The intent is to build something which when we need more than 50 users, we are
not causing down time for the current users, and can easily add resources.
>?Opensips -- Registrar and Proxy and hand NAT with rtpproxy
Everything would be behind firewalls but the users phones would be on the
public side, behind their own firewalls of course. So all servers would likely
be NATed.
So, look into Dispatcher, Registrar and Proxy which are modules or parts of
opensips if I recall.
>?use Dispatcher to loadbalance across Asterisk PSTN Round Robin basis
This I am unclear about at this time. Everything will be SIP/IAX based, no PSTN
lines will be used. We may have some PRI's here and there at some point but not
initially.
>?2 Opensips ( for loadbalance registration) replicate

While I had not seen this, I believed that opensips would have the capabilities
of being run redundant. I am also guessing that this could be done not only on
one LAN but perhaps in two different locations?
Don't suppose there's an ISO installable version which could be used to get a
better view of how things are set up.
