• Each media station consumes an Avaya IP Endpoints license seat the same as other Avaya
SIP endpoints.
Limitations
Consider the following limitations when administering the media station on IP Office:
• You must store the media station binary firmware image on a separate HTTP server. See the
media station release notes for more information.
• The media station supports either TCP or TLS as the SIP signaling protocol.

How dialing plans work
The deployment of a dialing plan in an enterprise consists of rules for telephony servers and rules
for endpoints. The combination of the dialing plan rules affects how users make calls to users within
the enterprise and to users outside the enterprise.
On an endpoint, the endpoint uses dialing rules that control automatic addition or deletion of dialed
digits based on options set on the endpoint. For example, if a dialed number matches a specific
pattern, the rules add some digits and delete some digits.
As one of several dialing plan methods, Avaya telephony servers often use the E.164 ITU-T
international public telecommunication numbering plan recommendation. E.164 telephone numbers
use the following pattern:
+CountryCode-NationalDestinationCode-SubscriberNumber
For example, the pattern +1-202-5551212 is an E.164 telephone number in the United States.
A telephony server configured to support E.164 ensures that calling the same number reaches the
same destination, regardless from where the call was made. For example, the user should not be
required to know the specific prefix digit or international code when making the call from different
locations.
You can blend E.164 support with other dialing plan methods such as direct extension calling. The
telephony server identifies an E.164 telephone number, determines that the number is actually a
local enterprise telephone number, and will not apply the dialing rules.
