  • Lync 2013 and Aastra/Generic SIP phones?


    Have a few hopefully basic questions here. Have spent some time searching but havenít come up with definite answers to our specific questions.

    Our situation: We are a small office, currently using 8 IP phones (Aastra 6755i) from 8x8. We have a Lync 2013 server, as well as a SIP trunk from a provider. We hope to use Lync and the SIP service to replace 8x8. This would accomplish two things: allow us to secure our SIP traffic (no TLS option at 8x and evaluate Lync for future use/resale. Many Lync functions may have use to our customers but have little value for our internal use Ė we are using it because a license is available through our Partner membership. The direction Iíve received is to proceed only if our existing phones can be used.

    Hereís my direct question: Can we connect our existing Packet8 phones to the Lync server? We DO need to replicate the functionality we already have: place and receive calls, transfer, park, VM etc. We do NOT care about presence or any other Lync-specific functionality.

    Iíve seen so many differing answers to this question that I donít trust what Iíve seen in forums. Our SIP vendorís feedback is that SIP-capable phones can act as SIP endpoints in Lync, however the prevailing wisdom I see in forums says this isnít possible, or it is possible only with a mediation server/proxy and donít bother.

    Any guidance offered will be helpful. Obviously, we are not immersed in phone tech and may be missing something fundamental here.

    You can't just use any 'old' SIP phone with Lync. So if your phone isn't listed here:

    Then it simply means your handset isn't supported for Lync.
