.
27979 Timeout waiting for reinvite to fax:

Normal Call Clearing instead. Error type:
RETRYABLE
.
27984 Unable to open even
RTP port followed by consecutive RTCP
port. Error type:
NON_RETRYABLE

27985 No Answer, remote device did not respond to handshake:
The call
connected and T.38 communication was established, but the remote device
failed to respond to repeated attempts to handshake. This commonly occurs
when using T38_INVITE to initiate T.38 media without the initial RTP audio
phase. The timer is 35 seconds. Error type:
RETRYABLE

The remote fax device is configured to
not receive faxes. Error type:
NON_RETRYABLE

The modem and the remote unit couldn’t fall
back to or agree upon any bit rate. This is most often caused by poor line condi-
tion. Error type:
NON_RETRYABLE
.
27988 Wrong response after training:
After sending 1.5 seconds of train-
ing data, the remote unit should have sent a CFR or FTT frame. It sent some-
thing else. Error type:
RETRYABLE
.
27989 No FTT or CFR received after 3 DCS/training sequences:
The call
connected and T.38 communication was established. The receiving and sending
devices exchanged CSI/DIS and TSI/DCS/training signals. After that, the re-
ceive side is expected to send a CFR (confirmation) or FTT (failure to train), it
did neither. Handshaking was attempted and failed twice more, at which point
IPFax terminated the call. Error type:
RETRYABLE
.

After reach-
ing the end of the page, IPFax sends an end-of-page command (MPS) and ex-
pects to receive an acknowledgment (MCF) from the remote device. IPFax did
