HI; iam bit new to IP telephony; say i have 1861 router with 4 FXS,4 FXO &8 port PoE sw, i understand that 8 IP fones will be connected to 8 port switch...my questions:
1- Can i plug normal analog fones to FXS (i believe i can) ; if yes than traffic will go to WAN or PSTN
2-FXO will use for what??? Are they serve
for same purpose as PRI's serve but giv
single call facility over WAN/ FXO port
If any body can elaborate when traffic go to WAN and when PSTN??? it really confuses me.
