> libpri does not handle keypad facility IE (44) in overlap mode so it is impossible to dial service codes ("numbers" beginning with star (\*) or hash (#)), see [^full_pri_debug-1.txt].
> In q931.c#post_handle_q931_message() when a Q931_INFORMATION message was received a PRI_EVENT_KEYPAD_DIGIT is fired only if call state is *not* Q931_CALL_STATE_OVERLAP_RECEIVING.
> According to the Q.931 specification "Either the Called party number or the Keypad facility information element is included by the user to transfer called party number information to the network during overlap sending".
> This was also discussed here: http://forums.digium.com/viewtopic.php?p=156228
> With the following patch
> Edit: Removed inline patch.  Richard Mudgett
> dialing service code works, see [^full_pri_debug-2.txt].
