The VOCAL SIP Analog Modem Server, or SAMS allows a business to deploy a server in the cloud, which can work with the modern VoIP phone network infrastructure based on SIP and RTP, instead of necessitating T1/E1 lines to connect to the PSTN. The Virtual Modem server contains true soft-modems, not just an AT command set on a TCP socket pretending to be a modem. This allows the server to connect to true voice band modems deployed on the PSTN, and thus does not require installation of additional equipment on the far end of the system. SAMS provides a true Modem over IP (MoIP) solution. VOCAL has server configurations supporting a broad range of modems. And because VOCAL has supplied the modem code for the RAS servers of the analog telephony world, you know that the modems are industrial grade.
Features
- 100% software solution easily deploys to the cloud
- Emulate and fully replace a physical modem
- Runs on any standard Linux or Windows distribution
- Replaces RAS equipment configurations when analog lines are being replaced with VoIP (SIP/RTP) lines
- Scalable – enables a large number of modems on a single server (10s to 100s depending on server and modem rates)
- Exports tty (com port) interface for each modem
- Each tty accepts industry standard AT commands – V.250
- Registers with one or more SIP servers (can be phone number per line, modem pool hunt, or other combinations)
- SRTP and Secure SIP options available
- Dialing commands will make outgoing SIP/G.711 call (with true modulation data in the stream)
- Incoming SIP calls will report RING to applications listening on ttys
- Compatible with ppp and pppd etc.
- Requires no analog audio interface
- Slaves to far end modem clock to eliminate skew
- High speed data modulation – V.34, V.90, V.92 (optional)
- Low speed data modulation – V.32, V.32bis, V.22, V.22bis, V.23, V.21
- Bell modulation – Bell 212, Bell 103
- Supports standard protocols such as V.42 / LAPM, MNP 2-4
- Supports standard compression protocols such as V.42bis and MNP5
- End of Support RAS / AS5350 / PVDM2 Digital Modem Module replacement
