Techical specification

- Aculab’s Prosody X VoIP-based products using SIP 2.0 can also be combined with any PSTN signalling protocol, including ISDN, SS7 and CAS protocols, to deliver powerful, cost-effective telecoms solutions.
- The ability to combine telephony functionality with signalling protocols enables single platform solutions, which are extremely cost-effective, compared to alternatives needing separate telephony hardware and signalling cards.
- Offering the same core VoIP or IP telephony functionality, Prosody S offers granular scalability and a viable, software-only, alternative to using telephony cards for SIP 2.0 in hosted, service provider or enterprise platforms.
- Using a download utility, developers can simply download the signalling protocol firmware, free of charge, when they need it – a distinct advantage in system cost and value per channel.
- Excluding SIGTRAN and dual redundant SIP (refer to white paper below), which are licensed, all signalling protocols, including SIP 2.0 and SS7, are freely available for use with Prosody X and Prosody S.
- Aculab has obtained many country specific, host independent regulatory approvals, meaning Prosody X can be integrated into server-based solutions without further telecom approvals being needed.
- As part of its support and professional services value-add, Aculab can offer assistance to users seeking system level type approvals in regions where host independent approvals are not available.
- Protocols for PSTN or ISDN connection, enabling deployment of a wide variety of global telephony solutions over E1/T1 trunks, include support for: QSIG; DPNSS; DASS2; NI-2; ETS300; and EuroISDN
- Support for signalling system number 7 (SS7), includes: SIGTRAN M3UA; SCTP; many national and international variants of ISUP; SCCP; TCAP; and MTP2/3
- Legacy CAS protocol support includes: T1 robbed bit (T1RBS); and many national and international variants of MRCR2
- Protocols for VoIP or IP telephony, include support for: SIP 2.0; SIP RFC 3261; and SIPS (TLS)
SIP compatibility SIP from: AcmePacket; Avaya; BT; Cisco; Level 3; microDATA; Polycom; Siemens; SNOM; Voxbone – works with most other SIP solutions.

Important note: ApplianX and GIII media gateways use Aculab’s signalling protocols packaged into a single, version controlled software build, therefore, signalling protocols shall not be individually downloaded and installed in an ApplianX or GIII.
