On frame relay perVC queue you can allocate mincir bandwidth (regardless of
your interface bandwidth and/or max-reserved settings). When mincir is not
configured it is 50% of cir, hence the issue. Try to configure mincir
768000 in map-class frame-relay 768k and your issue should be fixed.
BTW, Setting mincir = cir (and both equal to contracted CIR from you
provider) and switching off adaptive shaping are recommended settings for
voice.
Best regards,
Alexei

Could you possibly send configuration of your serial interface/subinterface,
QOS classes/policies, any frame class parameters (i.e. shaping) + IOS
version. As per earlier mail it so looks that IOS trusts you do not have
enough bandwidth to apply while you think different. The question is why.
Best regards,
Alexei

My policy-map gives a priority of 512. Under my subinterfaces I have
bandwidth statements of 768. So it is in the range. I also used the
max-reserved-bandwidth 100 command under the main interface with the same
result.

Yes. IOS by default reserves 25% of the configured bandwidth for overhead
traffic. So if your bandwidth statement says 768k, you can only reserve
576K.

Anyone seen this error message before? I tried putting on a service policy
to a map-class and got this:
I/f Serial0/0.17 DLCI 17 class voice requested bandwidth 512 (kbps)
Available o nly 384 (kbps)
