> I'm trying to work on disconnecting and reconnecting DAHDI MFC/R2 spans. This issue handles the simples form: manually destroying a channel while it is in a call. If it is not in a call, nothing seems to be wrong. If it is in a call, it crashes due to a segmentation fault. The attatched patch fixes the symptoms.
> To reproduce:
> 1. Configure a DAHDI channel (say, 3) as an mfcr2 channel
> 2. Start a call through it.
> 3. From the CLI, destroy it:  dahdi destroy channel 3 3
> Asterisk crashes immediately.
