Vigor IPPBX 3510 combines an IP-PBX (SIP Server), Firewall and VPN Server in one unit. It suits multi-branch offices that want to extend an existing phone system so sites can call each other at no extra call cost. It supports FXO/FXS and ISDN cards, a strong firewall, up to 32 VPN tunnels (voice security), and dual internet links so internal communications stay online. Beyond cost savings, it helps improve customer service — you can reach the office phone system easily from anywhere.
Vigor 3510 provides 1× WAN RJ45 and 4× LAN ports. For WAN backup, LAN port 1 can act as WAN 2. It supports 4 FXS and 4 FXO card ports for flexible integration with existing telephony, plus 1 USB port for a 3G link. Benefits of deploying VOIP include:
- Lower costs — traffic that travels over the internet incurs no PSTN call charges
- Integrates with existing Analog, ISDN and PABX systems
- Clear voice quality — DrayTek equipment can prioritize traffic for voice
Accessing Vigor 3510 is straightforward via Voice Phone (Vigor 350), Voice Box (Vigor Talk), or by connecting a PABX for internal and external lines through FXS and FXO ports. It supports up to 100 concurrent users/extensions and includes a softphone. Wherever you have internet, you can reach Vigor 3510. As a total solution with matching brand, chipset and protocol across devices, your VOIP system stays controllable and efficient.
