To select up to 4 SIP service Accounts

SIP-4FXS is appropriate to use four VoIP Service Providers, IP Centrex service and IP-PBX
within offices and remote branch offices. One of four SIP Servers ( or ITSP Service provider or
alternative IP-PBX ) can be configured freely at each line ( FXS port ) to make or receive IP Call.
It provides 4 service platforms to select lowest rate according to your dial number or country.

IPv6 VoIP Gateway is ready to Market

IPv6 address was developed for years, however, it was not practical to our life up to date. More and more electronic devices are able to link to IP Network, this makes existing IPv4 address supply in shortage to global market. Meanwhile, the emerging countries are not able to increase IPv4 address supply due to strong market demand on broadband services. SIP 4FXS is an SIP based FXS gateway which built-in both IPv6 and IPv4 IP address. No matter when you are ready to deploy IPv6 network now, or reserve the future expansion to IPv6 from existing IPv4 address, SIP 4FXS is ready to grow up with you. Both IPv6 and IPv4 address are working simultaneously at Voice IP Call. Its flexibility of both IPv6 and IPv4 accept and interwork both  addresses on today and tomorrow whenever you need.

Flexible Dial plan and Route Plan Features

SIP-4FXS provides flexible Dial Plan from FXS to IP Trunk (SIP Softswitch). Dial Plan is to configure in what condition the digits can be sent out to IP network. The dial inter digit time before dialing is configurable to meet busy users or home user. Dial Rule is able to detect the prefix code and maximum digits reached and then dial automatically. The Digit Manipulation (DM) allows you to configure matched prefix code, digits length, start and stop digit position to be replaced digits as well. Route Plan is to configure the incoming and outgoing call routes which you desired this call to go
out or allow to income. For instance, IP incoming call may Ring to FXS port with Priority, Cyclic or Simultaneously ring . You can also configure IP incoming call by Matched prefix digits, Matched incoming FXS line number and Matched digit length. For FXS outgoing call routes, the hunting type supports Priority, Cyclic or Simultaneously ring and select which SIP trunk ( SIP Proxy Server ) to go. FXS outgoing call routes also support by Matched prefix digits, Matched incoming FXS line
number and Matched digit length. Both direction supports No Answer time out and Backup Routes.
