It is recommended to upgrade this Avaya Product soon.
This product uses IP lines and SIP services to transmit the voice through the internet connection to the other party (data over the signal connection). Teltek’s Nebulosity Cloud PBX and Stratus Cloud PBX are systems which provide this service. We also can adapt analog devices (like fax) to our VoIP system.
The Avaya 5610SW IP offers the same advanced capabilities and calling features as traditional Avaya telephones. Stylishly designed, the phone incorporates functionality like a built-in headset jack, message waiting indicator, easily readable displays, and multiple programmable feature keys.Avaya 5610SW User Guide
