Victor, The other System successfully using the Red Flag 2.6.21-20 for COMMhad its base sysmtem otherwise at the Ubuntu 2.6.24 level. With yourbase System at 2.6.20, it is certainly possible that some off the PPPDrelater constituents are not fully compatible with the Red Flag2.6.21-20 kernel+drivers. Thus updating to Feisty 2.6.22 level or the current Hardy 2.6.24 levelmay be necesarry. But before doing that, send us the failure information on the call out.This will be the last several lines of /var/log/messages , just afterthe call attempt fails. If you have an alternate IP you could can online with without usingCall Back (which can be tricky by itself), do try that.
