Hi, the latest firmware promises ISDN Offnet Call Transfer which I hoped meant we could divert calls out over ISDN - i.e. incoming call can be diverted outbound to mobiles etc over ISDN. We can't find how this is done and Draytek support seem to think it can only be done over SIP trunks.

Anyone managed this?

thanks.

You can do that but it has to done using MSNs AFAIK - on the ISDN - general setup page click Advanced for the MSN and you can set CFU (unconditional), CFB (busy) and CFNR (no reply)
