Asterisk fax to emai/detecion bug

We have a Trixbox CE 2.6.1 server running centOS 5.2 and asterisk 1.4.20-1, we are also using a Digium PRI card. We have fax detection turned on so that faxes can be sent to a DID's email account. Asterisk will crash several times a day and restarts automatically, 90% of the time a fax is sent to a DID right before the crash. The other 10% of the time no fax is sent and Asterisk will still crash and restart on its own. We need this issued resolved so that the fax to email is functioning still and asterisk is more reliable and does not crash and restart. ## Deliverables Asterisk must be fixed so that it does not crash. DID's must be able to receive faxes via email.
