<br><font size=2><tt>Hello All,<br>
Im trying to work out a solution with a customer
to bring their <br>
current pots leased line system to a VoIP solution. The customer <br>
currently has a PSTN leased line from site A to B, which then plugs into
<br>
some type of intercom system each end(think of an analog phone on each
<br>
end with it off hook all the time).<br>
<br>
Is there anyway to do this over VoIP ?<br>
That is have an open link between say 2 x 1721 or 1751 cisco routers <br>
with FXS ports to have an non stop open stream between the FXS port at
<br>
each location. So when customer A presses the intercom button to connect
<br>
to site B its already open & there is no dialling between the 2 systems.<br>
Any suggestions or idea's would be largely appreciated.<br>
<br>
Cheers,<br>
<br>
Greg Maiorana.<br>
