View the new function >

The IP-SIP AD639SR loudspeaker, in IP56 enclosure, is part of a series of TEMA loudspeakers to be connected in a standard LAN network and is particularly suitable as a SIP repeater for incoming overtime telephone calls.

The system is activated when an incoming call arrives and emits tones or audio files prerecorded in its memory, easily replaceable via web browser.

External events

AD639SR is equipped with an auxiliary input for an external command, for example the entrance bell, to signal the visitor with a different sound from that of the telephonic call. It also integrates 2 programmable relays to activate external light indicators or other devices.

Light indicators

The system can be equipped with a multi-colored LED light to add an optical signal to the acoustic sound.

Simple installation

The installation simply consists of connecting AD639R to the LAN and registering it on an IP-PBX in the "Night" ringer group. The power supply can be supplied on the same UTP network cable by a PoE switch, or by an external 230Vac power supply in the Tema catalog, in this case the sound power will be higher.

Integration with VoIP SIP phone systems

AD639SR can be perfectly integrated with VoIP telephone systems (IP-PBX) with SIP protocol and can be registered as a regular VoIP phone or P2P Peer to Peer without a PBX.

Applications and Target

Operation as a SIP repeater

Following a call, AD639SR will make a loud sound contained in its memory and, at the same time, activate a LED or a FLASH warning light, if provided.
A second relay, which can also be activated by the presence of a SIP call, can be used for other external drives.

Numerous sound files supplied

The supply includes a large variety of sounds and ringtones ready in the format compatible with AD639R and with different characteristics according to the needs. Replacing the ringtone sound file is extremely simple and fast thanks to the AD639R embedded Web server.

Alarm signaling with telephone alert

AD639R can also be activated by an external signal being equipped with a special input to which an alarm contact, a sensor or a push button can be connected.


The AD639SR can simultaneously be used as an announcer to receive audio from a microphone on the network or from a SIP telephone equipped with the Multicast function, which will be played on the speaker.
