This is an always evolving setup and is far from perfect. I will update my notes here as I modify things. Also, if you think I can do something better, please let me know!

===== Cisco Notes =====
Here is an example of a basic VoIP config, translation-pattern, and dial-peer for an H.323 call to gewt
==== VoIP Configuration ====
voice service voip
no ip address trusted authenticate
allow-connections h323 to h323
allow-connections h323 to sip
allow-connections sip to h323
allow-connections sip to sip
Note: "no ip address trusted authenticate" disables automatic "toll fraud" preventions in modern IOS versions. Personally, I don't like it, and instead I use ACLs and/or firewall rules to block undesired IPs from hitting the ISR.
voice translation-rule 1010000
rule 1 /^......./ //
voice translation-profile strip_cac
translate called 1010000
This is to strip the "carrier access code" I use on my local network for SCDP calls (which is 1-222, a currently unassigned NPA)
==== Dial-Peer ====
dial-peer voice 1222415 voip
description GEWTTANDEM SCDP - H323
translation-profile outgoing strip_cac
huntstop
destination-pattern 1222415.T
session target ipv4:[IP_of_destination]
codec g711ulaw bytes 80
