Hello, I'm new about voice.Here is my requirement:
1.I have meshed site to site VPN among 3 locations, can I use Cisco ATA/Linksys PAP2 adapter to connect anolog phone and call the other two remote sites? These 3 sites can be assigned dial number like 10,20,30
2. if this not possible, can I use ATA186/linksys PAP2 as a "hot line" which is peer to peer without any numbers to dial?
3. if these VoIP adapter can not do so, what's your suggestion ? Thanks in advanced
