[hylafax-users] Unspecified Phase C/B errors

[Adam Engel <adamengel@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx>]

Hi All,

I am running Hylafax 4.1.1 on a RedHat 7.2 machine. Using USRobotics 56k 
Faxmodems.  We have about 12 fax lines going into 3 hylafax servers.

Lately I have been getting reports from clients that their faxes are not 
going through. I checked with the people that handle the actual faxes and 
found out that we drop an amazing amount of faxes during a week. We get 
hundreds of faxes everyday, and having dropped faxes is not good.

We are receiving "Unspecified Phase B" and "C" errors on the faxes that 
drop. I have pasted 1 of each occurance.

Here is the first, Phase C error:

What can resolve these errors? It would be nice to get these clients to 
stop calling me.

I have seen a great many posts about going to class 1, however I do not see 
any indication that I am using class 1 or 2.  I did not set these servers 
up, so I really don't know anything about them configuration wise.

Thanks,
