<body>the price of those appliance, I would say between $50.000 and $120.000 for 30 concurrent calls...<BR>
<BR>
The way to connect it: <BR>
<BR>
Softphone (IP) <-----> Asterisk (IP) <---- > Radvision <----> PRI< ---> (UMTS <----> 3G Cellphone)<BR>
<BR>
So from the softphone to asterisk : SIP (audio + video)<BR>
from asterisk to Radvision: SIP (Audio + VIdeo)<BR>
>From Radvision to PRI: 3GPP-H324M over PRI or BRI<BR>
<BR>
one call takes a single B-channel...<BR>
<BR>

<DIV><FONT face=Arial>Hi,</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>1. How much could cost such appliances (</FONT><FONT face=Tahoma>Dilithium or Radvision) ?</FONT></DIV>
<DIV>I thought it could be difficult to build valuable business cases for SME with such appliances.</DIV>
<DIV> </DIV>
<DIV><FONT face=Arial>2. Do you think these appliances could easily integrate with Asterisk today ?</FONT></DIV>
<DIV><FONT face=Arial>Reading this mailing list archive, I guess it is today possible to set things this way :</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>- Radvision appliance connects to Asterisk using one BRI or PRI port</FONT></DIV>
<DIV><FONT face=Arial>- Asterisk connects to PSTN-ISDN using another BRI or PRI port (hoping TDM bridging works faultlessly)</FONT></DIV>
<DIV><FONT face=Arial>- Radvision appliance and<FONT face=Arial> (soft or hard) SIP videophones register to Asterisk and belong to the same LAN</FONT></FONT></DIV>
<DIV><FONT face=Arial>- for outgoing video calls (from videophone to 3G cell phone), RTP flows are first passed through Asterisk to Radvision appliance, then are converted to H324M and then passed to ISDN-PSTN passing Asterisk again</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Is this correct ?</FONT></DIV>
<DIV><FONT face=Arial>How many B-channels per call are used ?</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Regards</FONT></DIV>

<DIV><FONT face=Arial size=2>Hi,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>This won't change 3G-324M stack development, but, is anyone aware of any (european) service provider offering 3G-to-IP gateway or MCU services ?</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Using an Asterisk registered SIP softphone (eyebeam, for example), someone would be able to call a 3G call phone for a voice and video conference.</FONT></DIV>
<DIV><FONT face=Arial size=2>Cost would be purely based on call duration or maybe based on subscribtion fees and call duration.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Cheers</FONT></DIV></BLOCKQUOTE><BR>
