Digital phone
An extension equipped with a digital phone can use the telephony features in an easier way than extensions equipped with analog phones. As the digital phones are equipped with preprogrammed keys for the most used features and programmable keys for other features (the most advanced also so called soft-keys and display), the features can be used without dialing procedures.

The digital signature is an encrypted digest of the file (message, document, driver, or program) being signed. This summary is computed from the contents of the file and then encrypted with the private key of the CA. To prove that the file was not tampered with, the recipient uses the public key to decrypt the signature back to the original digest, recomputes a new digest from the transmitted file and compares the two to see if they match. If they do, the file has not been altered in transmission by an attacker.

The forced gateway concept means for calls only involving IP end-points, that the media still must involve a media gateway, even if the end-points could have allowed direct-media connection. Configured by O&M.
For SIP extension and trunk it means:
No change in the established RTP socket (IP address/port) shall take place. The same RTP resource will be used from establishment until end of the call, and RTP media is terminated in a Media Gateway (no direct media between the end-points, even if they are of the same type). Still new SDP offers may be done, keeping the same RTP channel, but offering different media type (for example switch from RTP to T.38) or attributes (e.g. sendonly).

No H.245 Pause and Rerouting shall take place. There will be no change in the H.245 session from establishment until end of the call, and RTP media is terminated in a Media Gateway (no direct media between the end-points, even if they are of the same type).
