- Full SIP and T.38 support—Supports the complete range of industry standard VoIP: SIP, H.323, T.38 fax, fax and modem bypass, DTMF relay. Codecs G.729, G.723 etc.
- Transparent Telephony Features—Preserves ISDN features like caller ID and name (CLIP/CLIR), call transfer, hold, waiting, AOC. Supports DID and MSN lines in all major countries as well as complex numbering plan manipulations.
- Outstanding Interoperability—Interoperable for voice and T.38 fax with 3CX, Asterisk™, PingTel™ and other leading IP PBX systems.
Overview
The SmartNode 4554 ISDN BRI PSTN Gateway converts up to four simultaneous phone or fax calls from SIP or H.323 to BRI ISDN. It is a compact, reliable stand-alone VoIP gateway for IP-based voice systems which matches up to ISDN standards in terms of performance and quality.
Compared to PC-based solutions that combine IP PBX and a PCI BRI card, the SN4554 has several advantages: No need to install additional drivers or software, new services can be installed without downtime, several SN4554 can be combined and serve as redundant cluster, no ventilation or hard disk required, scaleable without limitation by the amount of PCI card slots available. Also, your system administrators don't have to learn ISDN, as industry standard protocols like SIP or H.323 do the job of connecting the PSTN to your voice system.
The SN4554 perfectly integrates in today's IP PBX systems supporting their advanced functionality, while preserving the majority of ISDN comfort features. Patton, as a leader in ISDN-VoIP technology, has integrated the following ISDN specific features into the SmartNode 4554: Advice of Charge (AOC), Explicit Call Transfer (ECT), CLIP, CLIR, 64k transparent data calls, support for both MSN and DID lines, overlap dialing, call waiting, call hold.
