I mean we have developed our pbx with call features and routing on asterisk only. If we switch to some other software that means we will have to redo a lot of development again. I was thinking of using DUNDi and distributing the registrations on different servers.<br> <br> I just dont get one point. lets say if i have 2 users registered on different asterisk servers and one of the server fails (dundi doea not get anything in return from lookup). But I can still get the contact information for the user who was registered on the failed server from db (realtime peer) for incoming calls. But what happens when that user tries to make a outgoing call? How do I redirect the call to the server which is still working?<o:p></o:p></span></font></p> <div> <p class=3DMsoNormal><font size=3D3 face=3D"Times New Roman"><span style=3D'font-size: 12.0pt'>On Mon, Oct 18, 2010 at 4:39 PM, Gareth Blades <<a href=3D"mailto:list-asterisk at skycomuk.com">list-asterisk at skycomuk.com</a>> wrote:<o:p></o:p></span></font></p> <p class=3DMsoNormal><font size=3D3 face=3D"Times New Roman"><span style=3D'font-size: 12.0pt'>Use camailio or opensips as the registrar server so it accepts the sip<br> registrations. You can have copies running on a couple of boxes using<br> either a shared databases or a database on each server configured in<br> master-master replication mode. Opensips can be configured to use the<br> same database table that asterisk uses for authentication. Then you can<br> use the load balancer module to send the call to whichever asterisk box<br> has the most free lines.<br> Normally you try and use opensips for most things such as call routing<br> and registrations and leave asterisk to do the application type stuff<br> such as conference calls and voicemail.<o:p></o:p></span></font></p> <div> <p class=3DMsoNormal><font size=3D3 face=3D"Times New Roman"><span style=3D'font-size: 12.0pt'><br> <snip><o:p></o:p></span></font></p> <p class=3DMsoNormal><font size=3D2 color=3Dnavy face=3DArial><span style=3D'font-size: 10.0pt;font-family:Arial;color:navy'>From what I have read, Asterisk and Kamalio can co-exist; some posters have used Kamalio to “supplement” the features that Asterisk either doesn’t provide or doesn’t provide in as nice a form as the OP desired – can’t really speak beyond this as I am not one of them.<o:p></o:p></span></font></p> </div> </div> </div> </body> </html> ------=_NextPart_000_010C_01CB6EAA.3AC2C610--
