i'm setting up a cisco 2821 as h323 voice gateway for a CUCM 6.X (i'md oing a migration from cucme to cucm).
This is the configuration h323 gateway config:
--- for inbound call---
voice class h323 1
h225 timeout tcp establish 3
dial-peer voice 69 pots
incoming called-number .T
dial-peer voice 223 voip
voice-class h323 1
session target ipv4:10.1.10.10
ip 10.1.10.10 is the cucm ip address.
---for outbound call---
all is working fine!
So, if i try to call 223 number, CUCM reject call.
223 is a directory number registered on CUCM that is working fine for outbound call.
make sure you're sending the call from the IP configured under CUCM
h323-gateway voip bind srcaddr ip_address
h323-gateway voip interface
CUCM only accepts calls from IPs he recognizes for H323
if this helps, please rate
