Call Pickup Group
Any extension SIP telephone endpoint can dial star “*” to pick up a telephone line that is ringing at a different
extension. If multiple telephone lines are ringing the oldest ringing line will be accessed.
Call Restriction
When making a telephone line call all digits dialed will be compared to the telephone’s Class of Service and restriction
table. The Call Restriction table allows the administrator to enter a range of digits (From - To), Trunk Access, Class of
Service (COS). The X-50 VoIP Telephone System has eight classes of service zero (0) which has no restrictions and
seven which is the most restrictive. The Call Restriction Table is made up of two tables an allow table and a deny table.
Each entry into either table is associated with a Class of Server. The combination of these entries make up the allow or
deny table. There are 40 call restriction tables and they work in the following way:
1. If there are no entries in either the allow or deny tables, all calls are allowed. If there are entries in either
table the calls are evaluated in the following order:
2. Deny Table - If the dialed digits match an entry in the deny table the call is denied. If the dialed digits do
not match an entry in the deny table, the call is sent to the allow table.
3. Allow Table - If the digits match an entry in the allow table, the call is allowed. If the digits do not match an
entry in the allow table, the call is denied.
Call Routing
When making a call all digits dialed will be compared to the rules entered in the Call Routing Table. The Call Routing
Table is built using up to 40 different routing rules. Each call routing condition (rule) directs the dialed digits to a
specific route and is made up of eight parameters, which include the “From” and “To” dialed digits, “Minimum” and
“Maximum” number of digits to evaluate, number of digits to “Delete” or “Insert” before dialing the numbers over the
“Destination” route (line group).
The call routing table is used to route calls over a voice network, which allows the administrator to route calls the most
inexpensive way. For example, in a voice network with locations in Boston, Chicago, and San Francisco calls with a 617
area code, can be routed to the Boston location, thus avoiding toll charges.
Call Waiting
The Call Waiting Flash supports the CO line flash, which allows extension users to pick up a call after receiving a call
waiting indication from the telephone line provider.
Caller ID
The system is equipped to received caller ID (requires a subscription) from the telephone line provider and will at
default passed the information to a ringing telephone (SIP or Analog) extension.
Class of Service
Each extension in the system is assigned one day and one night class of service of service, which determines the
extension’s dialing privileges. There are eight different Classes of Service which are defined in the Call Restriction
Table. A Class of Service (COS) of seven has the most restriction whereas a COS of zero (0) has no restrictions.
