Here can be set protocol parameters like slow start and fast start for H.323. Call start interwork allows translation between these modes. Protocol setting can changes be changed for particular dial peer bey i.e. by means of voice-class h323 commands or by appropriate commands directly in dial peers

Gatekeeper settings for ras session target in dial peers with primary and secondary gatekeeper. It is not necessary to configure it on Loopback interface.
There seems to be a BUG that affects H.323 slowstart to SIP calls if sip server is not set by ipv4:1.2.3.4.

N/A - There is only CISCO IOS
Validation, confirmation tests
Route call through IP2IP gw.
If you don't use sip server and gatekeeper, set dial peer destinations (session-target) directly to endpoints and call each other ( i.e. sip:numberofh323endpoint@ipofip2ip)
