Hi I am assigning traditional pstn numbers to sip accounts using aliases. i.e 0207xyz might point to iqbal(a)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
