[asterisk-users] Asterisk load balancing and failover

[Ngo-Vi Hoai-Anh]

I'm not quite sure what do you mean with MSC.

Anyway, I assume your environment is like

[PSTN (Public Switched Telephone Network)]<------------------>[DTM 
Switch]<-----------SS7  (PRI line)---------------->[Asterisk 
Box]<----------------VoIP (SIP/IAX etc...)---------> IP net

If you mean MSC Mobile Switching Center it could look like
[GSM Network]<------------------------->[MSC]<----------------- SS7 
-------------------->[Asterisk 
Box]<---------------------VoIP---------------------->IP net

Normally, the DTM Switch or MSC should be configurable for 
load-balancing and failover.

Point code is for SS7 networking like IP address for IP networking.
