The ascom VoWiFi system provides a reliable Voice Over IP communication solution that combines the
open standard for wireless radio networks and SIP telephony technologies. Utilizing the IEEE 802.11n
standard for wireless LAN (WLAN) communications, the ascom VoWiFi system provides the benefits of
increased speed, improved reliability and extended range of wireless transmissions.
The ascom VoWiFi system allows 2-way voice communications with residents via the Advent XT2 warden
call system and between staff, both internally and externally if required.
When the Advent XT2 is operating in onsite mode all alarm calls are reported via the VoWiFi system.
When the phone rings the caller will be identified on the display (provided the phone book memory is
programmed), when answered a voice message will announce the call type and channel ID before a speech
link is opened.
The ascom VoWiFi system comprises of 2 elements;
1. a bundled package including a Matrix IP-PBX, 2 x i62 VoWiFi handsets c/w chargers and PSU’s
2. a maximum of 8 x Draytek Vigor AP 903 Mesh Access Points
The Matrix IP-PBX is preconfigured so both CO analogue trunks ring all SLT and IP extensions, it also has its
DHCP server enabled. Both ascom i62 handsets have their WiFi settings and SIP credentials preconfigured
as extensions 151 and 152. A maximum of 5 IP extensions (151 to 155 are possible). The Matrix IP-PBX
allows the VoWiFi handsets to integrate with the Advent XT2 warden call system, it also allows access to an
outside line to make/receive external telephone calls and VoWiFi handset-handset calling.
One Mesh Access Point (known as the Mesh Root) is always hardwired to the Matrix IP-PBX Ethernet port
via a standard UTP Cat5e patch lead, max length 100 metres. Up to a maximum of 7 more Mesh Access
Points (known as Mesh Nodes) can be deployed wirelessly around the building to achieve site-wide WiFi
coverage. Each Mesh Access Point requires connection to a local mains supply using the plug-top mains
adapter supplied. If it’s not possible to power the Mesh Access Points from a local mains supply then they
can be powered from an auxiliary 12V DC power supply, but additional site wiring will be required. The
Mesh Root supports PoE on LAN Port A1, but an additional PoE switch or PoE injector will be required.
The size/complexity of the building will determine the total number of Mesh Access Points needed to
achieve site-wide coverage. The exact positioning of the Mesh Access Points will be determined by a site
survey prior to commencing the installation. A free Draytek Wireless App is available to simplify the setup
of the mesh network; https://www.draytek.com/support/knowledge-base/5683

Doc No. FM0855 issue 2 Page 4

MONTHLY MAINTENANCE
The Matrix IP-PBX and Draytek Vigor VP 903 Access Points do not require any regular maintenance, if any
items show signs of damage they should be replaced immediately by a Service Engineer.
Products needing repair can be returned via the website; www.tynetec.co.uk/returns-policy
ANNUAL MAINTENANCE
The rechargeable battery in the VoWiFi handsets should be replaced typically every 2 years or 500 charging
cycles. See the specification for the i62 handset in section 20 for details of battery type.
In the unlikely event that the VoWiFi system needs to be turned-off or reset, please ensure
all active calls are actioned before proceeding.

Doc No. FM0855 issue 2 Page 6
The maximum theoretical range for any VoWiFi system is 300 feet (92 metres) outdoors under ideal
conditions, in practice this range will rarely be reached due to reflections from nearby buildings, trees,
water, etc.
Obstructions inside buildings such as walls and floors will reduce the range, some construction materials
such as foil backed plasterboard, reinforced concrete or stone walls will reduce range further.
Environmental conditions such as high levels of transmission at nearby frequencies or emissions from other
electrical equipment may also reduce range.
Clear line-of-sight will give maximum radio coverage, it is impossible to state a specific indoor range in
advance of a site survey; however, as a guide you can usually achieve 150 feet (46 metres) radius from each
Mesh Access Point.
Locating the Mesh Access Point as high and free from immediate obstruction as possible will help to
maximise its range. Even if the Access Point is placed in the optimum position it may not always achieve
coverage in the most remote corners, if this is the case then additional Access Points will be required.
The Mesh Access Points should always be located at least 5 metres away from the Advent XT2 controller,
NTR’s or any other electrical equipment to avoid the risk of interference.
Mesh Access Points must be sited in a dry secure area; they are NOT suitable for outdoor locations.
AVOID LOCATING MESH ACCESS POINTS…
WITHIN 5 METRES OF
OTHER ELECTRONIC
EQUIPMENT
DIRECTLY ABOVE A
HEAT SOURCE
IMPORTANT NOTE:
Care must be taken during installation and commissioning of any VoWiFi system to ensure full coverage
and correct Mesh Access Point setup. Failure to follow the Manufacturer’s installation and programming
instructions may result in blind spots or calls dropping-out when moving between Mesh Nodes. Always
perform several test calls in all extremes of the building with both VoWiFi handsets in use.

The Draytek mesh solution supports a maximum of 8 Vigor AP 903’s in a mesh group, a mesh group
includes 1 Mesh Root and up to 7 Mesh Nodes.
IMPORTANT: Mesh Nodes can be a maximum of 3 hops away from the Mesh Root.
A free Draytek Wireless App is available to simplify the setup of the mesh network;
https://www.draytek.com/support/knowledge-base/5683
DEPLOYING MESH NODES
1. With your Laptop connected to the Mesh Root in Dashboard view, or your mobile device running
the Draytek Wireless App in Dashboard view, power-up the first Mesh Node in the desired location.
2. Check the dB level (signal strength) displayed for the newly deployed Mesh Node, it must be no less
than -73dB. For example -74dB or greater will be out of range and you need to move the Mesh
Node closer to the Mesh Root. If the dB level displayed is -66dB for example, then its possible it can
be moved further away from the Mesh Root.
3. Repeat this process for all Mesh Roots whilst checking the signal strength in Discovery Mode.
EXAMPLE DEPLOYMENT
MESH NODE FAILURE
If a Mesh Node fails, the surrounding nodes automatically re-connect and resume service.
assuming there’s sufficient WiFi overlap between nodes to re-establish a network link.
The mesh group self-organises
links between each node to
ensure the best possible speeds.
Mesh Nodes further away will
connect wirelessly to the

19. VoWiFi SYSTEM COMMISSIONING
This section describes the visual inspection and tests that must be performed after completing the
installation and setup of the VoWiFi system. The purpose of the visual inspection and tests is to verify that
the installation has resulted in a correctly functioning system. If it appears that a part is malfunctioning
while the system is installed correctly (that is, no cabling faults, no configuration faults), refer to the
Troubleshooting (chapter V) of the Draytek User Guide for fault finding.
WiFi COVERAGE VERIFICATION TESTS
The WiFi coverage verification consists of two tests:
• Mesh Access Point operation test
• WiFi Coverage test
IMPORTANT: ensure that the VoWiFi handset batteries are fully charged before performing the tests.
MESH ACCESS POINT OPERATION TEST
The purpose of this test is to check if all Mesh Access Points are operational.
1. Connect to the Mesh Root and view the Dashboard (or use the Draytek Wireless App).
2. Check the WiFi signal strength and route connections of all Mesh Nodes.
After having checked that all Mesh Access Points are operational proceed with the WiFi Coverage test.
WiFi COVERAGE TEST
The purpose of this test is to verify that there is satisfactory signal strength to enable good speech quality
everywhere within the covered area (rooms, lift shafts, staircases). This test is performed with two
handsets and requires two persons.
1. Use one handset to call the other handset. One user of the handset should now start moving
around the covered area. Both users must check that a good speech quality is maintained
everywhere. Special attention should be paid to areas such as edges of the building and areas
behind metal structures where there is a possibility of reduced speech quality.
2. Mark areas where audio break-up or mutes are heard.
When the WiFi Coverage test is complete the results should be evaluated. If the coverage is not sufficient
you should review the planning and re-locate or add more Mesh Access Points as required.
