[asterisk-users] Faxes suddenly failing

I realize that faxing is not great with voip but here is my confusion. I
have been working on a web based fax system for 2 weeks. During this time I
have sent over 100 2 page faxes without any errors. Now today as things are
finally completed I can not seem to get any fax to go through unless it is a
1 page cover only. Anyone able to tell the issue from this debug output?
