Re: [hylafax-users] patton 2977 configuration

[ACL <access_you@xxxxxxxxx>]

I noticed that 2977 does not busy out the channel after the caller is disconnected. There are two modems active (ttyG0 and ttyG1). I dial in (ttyG0), hear faxtone and hang up. Then, I dial in again at once. I hear nothing for a few seconds and then the same modem (ttyG0) begins answering again. If 2977 could busy out the channel, ttyG1 should pick up the call.

This causes me trouble because the dnis and callerid is missing in the log  for the  second call (no NDID and NMBR). If I dial in after the modem is idle, dnis/callerid appears in the log.

My telco routes incoming call to the next nonbusy channel. The above situation is very likely to happen. I will get a lot of faxes without dnis/callerid

BTW, I have been using 2977 in windows for a long time. The same situation happens. However, we could obtain dnis/callerid for every call by issuing at#cid=10 before call connection and just after call disconnection. Hylafax seems to issue at#cid=10
 only after the call ends.

Pls kindly advise.
