[Asterisk-Users] zaphfc problem: overlapdial don't work after update bristuff

[tuned at fan.priv.at]

hello,

I have a asterisk box (Slackware 9.1.0, Linux 2.4.31) connected to a 
Ericsson Businessphone PBX on the internal S0 bus with HFC-S card and 
zaphfc driver - point2point mode -.

   |  BRI  |

       | PBX external S0
    --------
    | PBX  |

       | PBX internal P2P S0 NT Mode
       |
       | HFC-S Card P2P TE Mode
   ---------
   |   *   |
   |  BOX  |

Since nearly one year it runs Asterisk 1.0.2-BRIstuffed-0.2.0-RC2b
fine. after dialing the internal S0 number (61) I get overlapdial and
dialtone.

[example dial the PBX S0 with Asterisk 1.0.2-BRIstuffed-0.2.0-RC2b]
     -- Accepting AUTHENTICATED call from 192.168.255.1, requested format = 8, actual format = 8
     -- Executing Dial("IAX2/ogo at call_saar/1", "Zap/g1/61|60") in new stack
     -- Called g1/61
Sep 23 10:27:50 NOTICE[229390]: chan_zap.c:8725 pri_dchannel: SETUP_ACK  for 'Zap/1-1'
     -- Accepting overlap call from '' to '<unspecified>' on channel 0/2, span 1
     -- Starting simple switch on 'Zap/2-1'
                    ^^^^^^^^
                             here I get a dialtone from PBX and I can dial
                             start dialing for 8 seconds

for different reasons I tried to update on latest bristuff-0.2.0-RC8n.
after update the zaphfc overlap dial don't work anymore.
when I dial the S0 bus it jumps directly into 's' extension,
which does not exisist in the context and I get 'no number' from PBX.
