Lync 2013 now supports M-N trunk routing. This allows you to have multiple trunks to
different gateways, and a gateway to have multiple trunks to different
Mediation Servers.This improve the flexibility and resiliency of the connectivity between
Mediation Servers and gateways.This section assumes that you have
already deployed Lync Server 2013 Preview on-premises and have enabled
users for Enterprise Voice.
Lync 2013 includes support for inter-trunk routing. This
feature allows Lync to act as an intermediary between two or more different
phone systems. For example, Lync can
accept calls from one PBX, and pass the call through to another PBX. This can
be very useful in larger environments and allows Lync to be the backbone of a
corporate telephone network.
Lync 2013 now
allows you to make changes to both the called and calling number. This is very useful when the PSTN provider
does not accept E.164 formatted phone numbers. For example, in North America,
many PSTN providers do not accept the country code 1 as part of the number and
only accepts 10-digit numbers. In the
past, an external gateway would have to do the necessary manipulation, but with
Lync 2013, all the number manipulation can be done in Lync.
There are also several other new Enterprise Voice related
enhancements. Delegates can setup simultaneous ringing to their mobile devices
for incoming calls to their manager. When a user has setup simultaneous ringing
to a mobile phone, and the device is turned off or out of range, Lync 2013 can
determine that an incoming call was immediately routed to voicemail, and
disconnect that endpoint so the call can continue to ring other endpoints.
Caller ID presentation allows administrators to modify the Caller ID format in
a much more scalable way than in Lync 2010, which only allowed Caller ID
changes based on the route.
