we use more than one CISCO 5400 as
VoIP terminations, since we are VoIP
We experience some trasmitting fax problem with T.38 FAX Relay.
It seems that many customer's CPE,
after CISCO 5400 Re-Invite, wait for
a T.38 packet before sending/receiving
But CISCO too wait a T.38 packet!!!
So communication hangs a while
then call is dropped.
We have seen that all CPEs that provide
a "T.38 No Signal" packet to CISCO
gateway after Re-Invite
succeed on fax trasmitting.
We use Cisco IOS Software (C5400-IS-M).
Is there any way to let CISCO sending
"T.38 No Signal" packets after Re-Invite?
Any help will be apreciated.
