Web Interface – Telephony
The

page allows you to configure the various telephony parameters of the Mediatrix 1204.
Digit Maps
A digit map allows you to compare the number users just dialed to a string of arguments. If they match, users
can make the call. If not, users cannot make the call and get an error signal. It is thus essential to define very
precisely a digit map before actually implementing it, or your users may encounter calling problems.
Because the Mediatrix 1204 cannot predict how many digits it needs to accumulate before transmission, you
could use the digit map, for instance, to determine exactly when there are enough digits entered from the user
to place a call.
Syntax
The permitted digit map syntax is taken from the core MGCP specification, RFC 2705, section 3.4:
DigitMap = DigitString / '(' DigitStringList ')'
DigitStringList = DigitString 0*( '|' DigitString )
DigitString = 1*(DigitStringElement)
DigitStringElement = DigitPosition ['.']
DigitPosition = DigitMapLetter / DigitMapRange
DigitMapLetter = DIGIT / '#' / '*' / 'A' / 'B' / 'C' / 'D' / 'T'
DigitMapRange = 'x' / '[' 1*DigitLetter ']'
DigitLetter ::= *((DIGIT '-' DIGIT ) / DigitMapLetter)
Where “x” means “any digit” and “.” means “any number of”.
For instance, using the telephone on your desk, you can dial the following numbers:
The solution to this problem is to load the Mediatrix 1204 with a digit map that corresponds to the dial plan.
Standards Supported
RFC 2705 – Media Gateway Control Protocol (MGCP) Version 1.0,
section 3.4 (Formal syntax description of the protocol).
Note:
The digit maps apply only on SCN to IP network calls. They are used on the second – IP – dial tone.
