RJ11 SIP line - Which module on router

Level 4
Level 4

Which module to add to Voice bundle router 4431 to receive/interface SIP trunk line (RJ11) provided by service provider?

What about CME license? CME licenses should be equal to extension provided in SIP trunk or number of IP phones and analog phones going to be deployed?

By RJ11 I beleve you are procuring Either FXO/FXS line or PRI Lines.
If it is Analog Line you can use FXO/FXS Module and For PRI T1/E1 Card.
FOr SIP Trunk you don't need any Moduel it will terminated on Normal Ethernet Interface.

CME License are not required for SIP Trunk Termination . You would need CUBE License

How many CUBE license should I add for 4431?

Cube license count = SIP extensions = 300 ?

Or Cube license = 30 trunks (SIP extension=300)(15incoming trunk and 15 outgoing trunk)

What about CME user license? Do we not need it for IP phones and analog phones?


Is below BOM ok?
