Aastra A1751-0131-10-55 6751i SIP desk phone with character display.

The Aastra A1751-0131-10-55 is the 6751i, a compact SIP desk phone featuring a character-based display. Designed for straightforward voice communication, this entry-level IP phone supports the SIP protocol for deployment across standards-based VoIP infrastructures.

The 6751i was positioned as an economical choice for basic telephony requirements, suitable for common areas, lobbies, or workstations where advanced features are not essential. It integrates with Aastra PBX systems as well as third-party SIP-compliant call platforms.

This model is part of Aastra’s legacy 6700i series, which predates the Mitel acquisition. Whilst discontinued, the 6751i remains functional in existing deployments and is sought after for spares or like-for-like replacements where maintaining a consistent fleet is preferred over wholesale upgrades.
