> This issue is reproducable in the following way:
> Call comes in on ISDN (CAPI) channel, Asterisk connects to SIP (going via MS Lync to Exchange 2010 UM). UM server tries to forward call to another extension on ISDN (Alcatel PABX). Lync sends SIP INVITE to Asterisk, ISDN line starts ringing.
> If I then hang up incoming call (ISDN->*sk->Lync), the Lync->*sk->ISDN call doesn't stop ringing. When call is answered, Asterisk crashes:
> {noformat}

> Asterisk ended with exit status 139
