[Asterisk-Users] Problem with ZAPHFC: internal S0 hangs when hanging up

[Sven Fischer]

Hello all,

if I try to call from one phone on the internal S0 to another on the same S0
using zaphfc, the bus is hung up. The called phone is ringing, but I can't
talk from one phone to the other. The error I get is:

    -- Executing Dial("Zap/2-1", "ZAP/1/55|15|tr") in new stack
    -- Requested transfer capability: 0x00 - SPEECH
    -- Called 1/55
    -- Channel 0/1, span 1 got hangup, cause 42
    -- Zap/1-1 is circuit-busy
    -- Hungup 'Zap/1-1'                                                         

The called phone is still ringing, if I have hung up the calling phone. I
have to restart asterisk to get things going again. Calling from SIP to the
phones and calling from phones to external ISDN is working fine.

For a closer look to the dump, I have attached the bri debug output from
asterisk.

Asterisk is 1.2.4 compiled from newset bristuff (1k), zaphfc patched with
florz patch. 1 AVM ISDN PCI and on HFC PCI, which shares interrupt with
eth0 (if it matters).

Has anyone an idea what is going wrong here? May I provide additional
information to solve this problem?

Thanks for your help,
Sven
