Can I use SPA8800 in VoIP network? I mean will it be clear configuration and vision when there aren't needs and possilibities to install ISDN PRI line on the remote branch office but presents analogue FXO line.
I recommend you only use Cisco IOS GW for FXO. You can also use ISDN BRI that is very feature-rich.
Linksys products are really only consumer grade and can give you a lot of problems.
