Asterisk 1.8 DAHDI 2.5 ISDN overlap dial problem!


I have a big problem! Overlap dial was working before.

Now I have the problem that on incoming calls the call is answered after the first digit. You hear still signalling a rining. After 3 Seconds a “Invalid Number” is present. No other digit is received by asterisk.

Now I found, that I did not receiving any INFORMATION Packets after SETUP COMPLETE…

If I dial the same number on block then everything is ok.

I tried so much but I cant find anything about overlap dialing.

DAHDI 2.5.0
libpri 1.4.12

Please help.

Best Regards
