IP Telephony FAQ's:
SONET is fiber with telephony
heritage
SONET was designed to carry telephone conversations, so it handles
the TDM (time division multiplexing ) digital voice channels from
PBX and telephone carrier switches easily. Because it is synchronized
like the T-carriers, you can add or remove channels at will with
an add-drop multiplexer. This makes it easy to interconnect a
group of locations in a regional or even nationwide network.
What is SIP Trunking?
A SIP trunk carries multiple VoIP phone calls from an enterprise
to another location, including third party call termination services.
SIP or Session Initiation Protocol, refers to the signaling protocol
that accompanies the voice packet stream.
