I would like more information on H.323 gateway call preservation. I currently have a 2811 with an E1 PRI. The gateway is configured as an H323 gateway and connected to our Callmanager 4.13 this way (H323 gateway). The gateway is planned to be used as a branch office gateway and therefore it is configured with it own VOIP DHCP pool and Cisco 7961 phones connected to a branch switch. I have simiulated a WAN connection via a Branch firewall to replicated the Branch situation. So visually like this E1 -> 2811 ->Switch with phones -> Firewall -> Callmanager. The 2811 default route is via the firewall. All phones and 2811 are on same VLAN.
I can get an inbound call with an associated dial-peer to route (setup and RTP audio stream) to an SCCP Branch 7961 phone, but when I "bring down" the WAN connection I lose audio both ways (Call is not preserved). The following commands have been issued:
voice class h323 1
h225 timeout tcp establish 3
no ip address
no ip mroute-cache
encapsulation dot1Q 200
ip address 10.100.100.2 255.255.255.0
h323-gateway voip interface
h323-gateway voip bind srcaddr 10.100.100.2
dial-peer voice 20 voip
voice-class codec 2
voice-class h323 1
session target ipv4:10.100.0.52 (Callmanager)
incoming called-number 9
ip route 0.0.0.0 0.0.0.0 10.100.100.1 (Firewall)
It would appear that the RTP audio stream is going to the Callmanager and back. Why would this happen, I assume once the Call Setup is completed the RTP stream should be between the E1 Voiceport and the local IP Phone.
Phones are configured to use the 2811 as default gateway, option 150 is set to retrieve config data from the Callmanager.

The below trick might come handy when you have to add a new node to a cluster but you don't have or is unsure of the security password for the publisher. This procedure has been around for ages.
