This section provides instructions on how to configure the IP DECT stand and 5610 Cordless Handsets to support SIP telephony.
- IP DECT Stand supports up to eight handsets and three simultaneous calls
- Each handset can be programmed as a separate extension on the silhouette system or you can program the cordless handsets in a personal ring group to allow a group of users to answer calls to the same extension number

Requirements and Conditions
- Roaming (call handoff) is not supported between IP DECT stands.
- Although you can register up to eight handsets with an IP DECT stand, the stand only supports up to three simultaneous calls. If three calls are already in progress via the IP DECT stand, any other handset users who attempt to place a call will receive busy tone.
- For site applications where all the users registered to a stand are expected to place calls frequently, register a maximum of three handsets to the stand. For site applications where users will seldom place calls, it may be suitable to register more than three handsets to a single stand.
Using a Repeater
You can have up to six DECT repeaters connected to an IP DECT stand to extend handset signal range. Note that each repeater that you connect to the stand reduces the number of supported handsets by one. For example if you connect one repeater, then you can only register seven handsets; if you connect two repeaters, then you can only register six handsets. After registration is complete, the LED on the repeater remains on solid. While the repeater is supporting a call, the LED on the repeater flashes.
After installing a DECT repeater, test the signal range to ensure that the repeater has registered with the stand. Test the handset signal range by going to the limit of signal range. If the repeater has registered with the stand, the handset signal range should be approximately 50 meters (indoors) or 300 meters (outdoors) from the repeater.
Repeaters can be used to extend the signal in all directions but cannot be used in a series with one another.
