Summary:                    [patch] Limit octets received on Called Party Number
and Calling Party Number
Description: 
Currently we can change the CallerID(num) from the dialplan to be longer
than the limit.

The senario we have come across, incorrectly resubmitted the call back to
the trunk, after adding digits to the caller id. Finish up at 27 digits
long!

The call then came back to us, with a new callerid number.

When the callerid gets to more than 20, the data starts becomming corrupt,
telltale '©' character starts to appear.

uploaded limit_transmit_length.diff.txt

Following q931.c:transmit_user_user() style which limits length in
accordance with Q.931 specification, also limit
transmit_calling_party_number() and transmit_called_party_number().
