Unable to make outbound calls from the IP phone

Hi,

Is the IP address 192.168.1.18 correct?

The call comes in and matched outgoing dial-peer 107 which sends the call to that IP address.

Call disconnects with cause value 38 (network out of order).

Make sure the IP address is correct and reset the H.323 gw on CUCM.

Also, you have an H.323 binding being on the interface with the address 10.0.40.4. make sure that interface has connectivity to CUCM and make sure that is the interface configured on the H323GW on CUCM webpage.

Please rate this post if it was helpful.

Thanks,

out of order happnes sometimes due to the H323 binding commands missing

configre the H323 commands for binding on the interface/IP used in CUCM for this gateway

some things to check, be sure that you have h323 bind commands in gateway set to same address that you use to build the gateway in CUCM, and that the gateway there has valid CSS, and that the route list your patterns point at is registered. If all that is true, then you might be hitting the new IOS toll fraud prevention scheme, might need to either disable it or add our internal addresses: http://www.cisco.com/en/US/tech/tk652/tk90/technologies_tech_note09186a0080b3e123.shtml

quick things to check, without looking at your config yet - make sure you have the H323 bind commands to the same address that you use to build the H323 gateway, and that the gateway has a CSS that allows calls to the phones, and that the gateway route list is registered - then you might need to look into modifying the new IOS toll fraud prevention scheme - either by disabling, or adding your addresses to allowed list: http://www.cisco.com/en/US/tech/tk652/tk90/technologies_tech_note09186a0080b3e123.shtml
