<P><FONT face=Arial><SPAN class=750144423-24092003>Dear All,</SPAN></FONT></P>
<P><FONT face=Arial><SPAN class=750144423-24092003>I am going to deploy a VOIP
network here in Canada with nodes all over town. This is for long distance
services and hence would need a good reliable solution.</SPAN></FONT></P>
<P><FONT face=Arial><SPAN class=750144423-24092003>I have looked into * and am
very interested in it with all the value-added features as well as its
capability to do H323 and SIP. I understand that a good portion of VOIP
operators in the industy is converting to SIP but there are still more H323 VOIP
operators out there. That is one reason why I am interested in this solution as
it can do both.</SPAN></FONT></P>
<P><FONT face=Arial><SPAN class=750144423-24092003>Most of my customers and
carriers are still on H323 and hence I would need to make sure that the * is
able to talk with most H323 gateways out there in the market, such as cisco and
quintum.</SPAN></FONT></P>
<P><FONT face=Arial><SPAN class=750144423-24092003>There are two things I would
like your comments on to make sure that the system will serve my purpose. I need
my carrier customers to be able to send calls to my * via H323 VOIP from most
H323 gateways and the * to pass through and route the calls to appropriate
carriers with cisco or other gateways via VOIP, the process will be H323 mostly
and some SIP, working with G723 and / or G729 which are what most VOIP operators
are using. In this situation, the inbound and outbound are both via VOIP, either
with H323 or SIP with both G723 and / or G729 codec. Is the application, is *
compatible with most gateways out there?</SPAN></FONT></P>
<P><FONT face=Arial><SPAN class=750144423-24092003>Another situation is carrier
customers will send calls to me to be terminated on the TDM circuits OR I
originate calls from the TDM side to be terminated on any gateways on the
carrier side. In such, there will be a encoding / decoding process. Would I be
able to send calls to most other gateways from my TDM circuits via VOIP H323 or
SIP on g729 / G723 codec? Likewise for customers calling into my *, would the *
be able to decode G729 and G723 to pass calls to the TDM side?</SPAN></FONT></P>
<P><FONT face=Arial><SPAN class=750144423-24092003>I would love to get some
feedbacks and advices (which is greatly appreciated) from you all who have had
experiences in doing this before, thanks a million.</SPAN></FONT></P>
