I still think your pstn provider has configured the link to send the last
two digits as overlap digits instead of using enbloc dialing (sending the
whole number at once after dialing is completed). Did you try enabling
overlap dialing on that line ("overlapdial=yes" in zapata.conf)?
The "Called Number" was not marked with "Sending Complete" by the pstn so
there may be overlap digits sent as information elements. By setting
DEFAULT_CIDRINGS I think you forced asterisk to wait a bit longer. Setting
"overlapdial=yes" should make it wait until the pstn provider sends
"Sending Complete".
For some reason asterisk is sending "Call Proceeding" which tells the
other end of the isdn connection that no more digits is needed. It has
enough information to process the call. Are you sure there are no rules
that could match only the first 6 digits? If not i really do not see what
is going wrong. Asterisk should accumulate digits until "Sending Complete"
or a match is found in overlap mode.
If you run a "pri intense debug" on your modified asterisk with
DEFAULT_CIDRINGS, do you see more digits coming in in information
elements?
If you fail to get asterisk to work correctly you could ask your pstn
provider to configure the isdn link to send the called number indication
enbloc. They should be able to configure that.
