**EDIT**
I managed to solve the problem. i wasn't using CUBE on the HQ or PST routers.

I'm attempting some 'advanced gatekeeper' work. I've created a Gatekeeper on R1 at HQ. I have registered R3 at SC into the GK. Calls are working correctly.
I've then attempted to direct calls to a third-party gatekeeper zone. I did this by setting up a H323 interface on the PSTN router and a VOIP dial-peer to match the incoming call:
interface Loopback2
description **Address for SIP/H323 Trunk
ip address 167.26.1.253 255.255.255.255
h323-gateway voip interface
h323-gateway voip id R1 ipaddr 162.102.64.254 1719
h323-gateway voip h323-id RGGK
h323-gateway voip bind srcaddr 167.26.1.253
end
dial-peer voice 4020 voip
incoming called-number 01144.
The incoming GK calls terminate on the PSTN's '911 line'
Next I configured the HQ router:
interface FastEthernet0/0.102
encapsulation dot1Q 102
ip address 162.102.64.254 255.255.255.0
ip helper-address 162.1.64.254
h323-gateway voip interface
h323-gateway voip id R1 ipaddr 167.26.1.253 1719
h323-gateway voip h323-id HQ
h323-gateway voip bind srcaddr 162.102.64.254
end
I updated the GK config:
gatekeeper
zone local GK cisco.com 162.102.64.254
zone local R1 cisco.com
zone remote RGGK cisco.com 167.26.1.253 1719 outvia R1
zone prefix RGGK 01144*
no shutdown
I added a GK Route List and 901144! Route Pattern to CUCM. Calls are connecting correctly with two way audio. However, when I execute a 'show voip rtp connections command on R1, it says there are no active calls:
R1#sh voip rtp conn
No active connections found
However, the PSTN router does detect an active call:
PSTN#sh voip rtp connections
VoIP RTP active connections :
No. CallId dstCallId LocalRTP RmtRTP LocalIP RemoteIP
1 154 155 18916 22888 167.26.1.253 162.102.64.10 (HQ PH1 IP address)
Found 1 active RTP connections
Is this expected behaviour?
The guide I'm using states that R1 should have two RTP streams - both terminating on the voice vlan IP (162.102.64.254).
