[cisco-voip] DHCP not really working

[keli at carocomp.ro]

I don't have a helper address there. I tried, pointing it to it's own  
IP, but obviously it just got worse :)

Anyway, the phones have the Administrative VLAN set manually, since  
they are on a Dlink PoE switch, however, they were working ok before  
... and seemingly the phones ARE trying to get an IP on the proper  
interface.

Here are some more configs: 0/1.2 is the voice VLAN

interface FastEthernet0/1
  no ip address
  duplex auto
  speed auto
!
interface FastEthernet0/1.1
  encapsulation dot1Q 1 native
  ip address 192.168.181.230 255.255.255.0
  h323-gateway voip interface
  h323-gateway voip bind srcaddr 192.168.181.230
!
interface FastEthernet0/1.2
  encapsulation dot1Q 42
  ip address 192.168.42.1 255.255.255.0
