[Serusers] aliases and inbound pstn numbers conflicting

[Iqbal]

Hi

I am assigning traditional pstn numbers to sip accounts using aliases.
i.e 0207xyz might point to iqbal at sip.gigo.co.uk

problem with this method, is that when serweb is used to register a new
account, it looks for the last number in aliases and adds one, so a
normal sip account now has an alias like 0207865473

Is there a better way of doing this, I was thiking of putting inbound
pstn numbers into another table instead, and then doing a lookup to it
from ser.cfg, or is there a way of getting serweb to ignore certain
numbers with certain flags set.

tks

Iqbal
