OT: VoIP H.323 gateway/gatekeeper question

Can one router act as a gatekeeper and a gateway (registering with its self)?

Scenario:

I have a 3600 with a couple of FXO VICs in it, and a couple of ATA-186 endpoints.
The 3600 FXO ports are connected to a phone switch.
Each of the ATA-186 endpoints connect via the internet (cable modem or DSL, and have DHCP addresses).
The goal is to setup each of the stations as PLAR OPX extensions

3600 ATA-186 #1
voice 1/0/0 <-> port 1
voice 1/0/1 <-> port 2
ATA-186 #2
voice 1/1/0 <-> port 1
voice 1/1/1 <-> port 2

This all works okay, if I use static mappings (no gatekeeper); that is, until one of the ATA-186 endpoints get a different IP address DHCPd to them from the ISP

I can get the ATA-186 endpoints to register successfully with the gatekeeper, but I cannot seem to get the 3600 to register as a gateway with its self So Im wondering if it is even possible Do I need to split up the gateway and gatekeeper for it to work, or am I just missing something?

Im running 12.3.10a, here is a simplified copy of the config that Im working with on the 3600:


!
voice service voip
!

!
interface ethernet0/0
  ip address 10.1.1.1 255.255.255.0
  full-duplex
  h323-gateway voip interface
  h323-gateway voip id gatekeeper.domain.com ip addr 10.1.1.1 1719
  h323-gateway voip h323-id gateway.domain.com
!

!
voice-port 1/0/0
  connection plar opx 200
!
voice-port 1/0/1
  connection plar opx 201
!
voice-port 1/1/0
  connection plar opx 202
!
voice-port 1/1/1
  connection plar opx 203
!
dial-peer voice 100 pots
  destination-pattern 100
  port 1/0/0
!
dial-peer voice 101 pots
  destination-pattern 101
  port 1/0/1
!
dial-peer voice 102 pots
  destination-pattern 102
  port 1/1/0
!
dial-peer voice 103 pots
  destination-pattern 103
  port 1/1/1
!
dial-peer voice 200 voip
  destination-pattern 2..
  session target ras
!
gateway
!
!
gatekeeper
  zone local gatekeeper domain.com 10.1.1.1
  no shutdown
!


Output of show gateway:
H.323 ITU-T Version: 4.0 H323 Stack Version: 0.1

H.323 service is up
Gateway gateway.domain.com is not registered to any gatekeeper

Alias list (CLI configured)
H323-ID gatekeeper.domain.com
Alias list (last RCF)
H323-ID gatekeeper.domain.com

H323 resource thresholding is Disabled

Thanks!
