Voice Over IP Gateways - The KX-TDA IP PBX system can be equipped with an optional VOIP card that permits you to connect the system to your existing data network providing an inexpensive alternative to route calls between two KX-TDA IP-PBX systems.

The KX-TDA50G features built-in software that digitally integrates the Panasonic voice processing systems. Thus providing proprietary high-speed communication between the PBX system and the voice processing system. There are 2 voice processing models to choose from, each containing a built-in auto attendant, interview service and voice mail.

Caller ID/Call Logging - Caller ID displays the incoming caller's phone number, or name and number (if provided by the local phone company), when used with a Panasonic system display phone. The user at each extension can log up to 30 answered calls, while unanswered calls are logged automatically. Logged calls can be called back by going off-hook while viewing the INFO screen and pushing the redial key. There are also up to 1000 programmable entries of name and number for Caller ID service that can be administered by either the user or the system programmer.

Conferencing - The KX-TDA50G systems allow the user to have multiple conference calls from 3-party up to 8-party calls at the same time. This feature can prove to be quite beneficial for those who do a lot of conference calling within the same company and may otherwise need an external conference service.

Universal Call Distribution - Having Universal Call Distribution is an inexpensive alternative to adding an additional call center. With Universal Call Distribution incoming calls are evenly distributed to operators or agents logged into a specific UCD group, such as required by a travel office, customer support center, etc. Four different outgoing messages can be recorded and played back in a cycle, and a separate extension can be assigned for overflow calls. Members of a UCD group also have the capability to temporarily remove themselves from the group. This allows members to go to lunch or finish paperwork before taking another call. They can then return to the group when they are ready to answer calls.

Direct Inward System Access (DISA) - With the optional KX-TDA0191 4-Channel Message Card, the KX-TDA100 and KX-TDA200 systems allow an outside caller to access specific system features without operator assistance, as if the caller had an extension in the system. The outside caller can have direct access to the following features: single-digit access to extension, outside party calling, intercom calling to an extension, modem (for remote system administration), external pager, phantom extension and extension group. Additionally, callers can be required to dial a security code to access extensions or the systems outside lines.

Account Codes - Account codes can help manage your telephone expenses by identifying incoming and outgoing external calls for accounting and billing purposes. The system can be programmed to force the use of an account code or not. The account code is appended to the Station Message Detail Recording (SMDR), which is very useful for billing back clients, or to simply keep record of the time spent on the telephone for a specific project.
