<DIV><FONT face=Arial size=2>If you just want all users to register with "Domain
A" and call over a single SIP trunk to "Domain B" that would be fairly simple.
You have all the phones register on "Domain A" and set that all calls got
through trunk X to "Domain B". If you want "Domain B" to call a specific phone
connected to "Domain A" then it might be a bit trickier. </FONT></DIV>

SIP to SIP Gateway</DIV>
<DIV><BR></DIV>Hi,<BR><BR>It is my second time when I try to use asterisk
:)<BR>I am starting with the following issue.<BR>I want asterisk to behave as
a gateway between two sip networks.<BR><BR>My architecture is the
following:<BR><BR>SIP proxy (registrar - domain A)
--------------- Asterisk Gateway ------------------------ SIP
proxy (registrar - domain B)
<BR>
(number of UAC registered in domain B)<BR><BR>Asterisk form the point of view
of the domain A and users registered in A is outbound proxy and from the point
of view of domain B is a set of SIP clients. <BR>Is it possible to configure
asterisk in such way that for a particular user from domain A who calls
through asterisk <BR>the SIP signaling will be passed through some pointed
user (asterisk user logged in domain B).<BR>It is easy to achieve that in the
other direction. when there is a connection from domain B to a particular user
which was registered<BR>by asterisk. One can forward such connection to some
user registered in sip proxy in domain A. <BR>Please point me how can make
such a mapping between the calling user from domain A and a user in asterisk
who is registered in domain B??<BR><BR>Thank You in
advance.<BR>Regards<BR><BR>Tomasz<BR><BR>
