I wonder if it's on the P400 side then, it receives a 64K call but does not handle it correctly since you upgraded the remote site....that'll take some investigation to pin down.... >> >Is there a possible problem of me requesting a 64k channel, the phone >> >company giving me a 56k channel, and not telling me that it is 56k?

Not directly, but there will be a clue in one of the ISDN messages that says the call is not ISDN-end-to-end.... >I'm not anxious to drop back to an earlier version of the software, but >If it is only me who seems to be running into the problem, and I'm >thinking that it is related to my software upgrade, and not the telco, Well if this definitely worked in an earlier version, it's hard to point fingers at the telco.... >then I'd do it to help figure out what is wrong.
