We are using asterisk with a2billing for a calling card platform,
at the moment we are using 1.4 however want to upgrade to 1.6
Does 1.6 have clustering function built-in and is it wise to plan to pass millions of phone calls a day?
If let’s say we run asterisk on cluster of Servers to gain a achieve CPU and memory resource.
High Availability and speed is the big issue. we’ve been thinking to switch to freeswitch.
or maybe we place the OPENSER in front of asterisk. will we be able to use all voice functions
like meetme, voicemail etc while combining with OpenSER
