I don't want the endpoints to register with arbitrary numbers. I have this capability for aliases in [RasSrv::RRQAuth] section, but is there any way to use this for the numbers? > Your 2nd issue is caused by the fact that GnuGk can only see the IP of > the immediate next endpoint/neighbor sending the call.

I've temporarily solved the problem by removing the most painful numbers from the AcceptedPrefixes list in the [Neighbor::...] configuration. But this solution is very coarse and doesn't suit my needs completely. Even if originating IP addresses are not available (I've already found that from packet sniffing), I'd like to filter at least based on source numbers - those seem to be present in RasMessage->admissionRequest->srcInfo->dialedDigits (semantics based on Wireshark). We have this capability for aliases in the [PrefixAuth], but would it be possible to make it work also for numbers? Thanks a lot!
