One bug I found with SunUNIX 'tip', possibly still existing, was that
it wouldn't communicate with Hayes-compatible 2400-baud (USR Courier).
The Courier had a default status code set that was different from
the Hayes 1200 one, so when it made a 2400-baud connect, it returned
a status code which tip couldn't recognize.  Fix was/is to MANUALLY
enter the following whenever the modem is powered up (what you type
is preceded by a tab or prompt:

blorp% tip cua0
connected
	ATX0	< this is not echoed >
0
	~.
disconnecting...[EOT]
blorp% 

ATX0 selects the ordinary 1200 status codes.  Reason I write is
the symptoms were something like to what you described: even though 
the remote site was picking up fine, I'd always get 'call failed'.
good luck
