one way IP trunking

[CoryCuster]

Getting an out of service error calling from one 3300 ICP to another. It’s a clustered environment with 12+ Nodes. Mixture of MCD 5.0 and 6.0 w/ SDS. System is synchronized with the cluster incl. telephone & remote directory.

- It throws no ICP Comm alarms or any other alarms within the admin group or cluster.

- RMESS command from multiple PBXs confirms that the controller is communicating w/ cluster

- The internal calls flow the other direction perfectly w/ SMDR records. Dialing the other way (into the facility w/ IP trunking) however gives an out of service error and no SMDR activity. We can however register DN from the facility remotely (though still get the out of service error when calling it) as well as taking a DN & phone from another facility and power it up and get two way dialing.

- I have gone through all the relevant forms multiple times and even had a second set of eyes look.

Network Elements
Cluster Elements
ICP/PBX Networking
IP/XNET trunk profiles
IP/XNET Trunk Groups
ARS Digits Dialed
ARS Routes

The only known unknown is that the facility in question has a 70 – 80 ms ping time from all other locations at no load (it is a new facility and a peculiar network as it resides across a border with a different ISP and they are working on the latency).

All other functions at the facility work – computers, internal ext. dialing, dialing ext. to other facilities, etc. it just cant dial into facility through IP.

Have you recently upgraded any of the controllers?

It happened to me once that after upgrading, one of the network element numbers introduced a blank space and I didn't noticed until I had to clear and reprogram my ip trunks.

Make sure for all network element you have the number with no blank space to the left of the index.

Cheers,

Daniel

All controller checked out and everything looks good

here is some additional info as an FYI

Thanks for the quick response

we took an office phone from another facility to the site in question. it booted up - though sat on the "loading applications" screen for an unusual amount of time. eventually it came up, pulling local DHCP and worked perfectly.

the two PBXs are communicating

RMESSAGE: Connected to PBX200
RMESSAGE: Verification successful to PBX200
RMESSAGE: Disconnected to PBX200

RMESSAGE: Connected to PBX223
RMESSAGE: Verification successful to PBX223
RMESSAGE: Disconnected to PBX223

I pinged my phone from the PBX in question as per a suggestion from ralph

PING 172.17.34.76: 56 data bytes
64 bytes from 172.17.34.76: icmp_seq=0. time=80. ms

and then the other way from the 3300 my DN resides to a phone there. all looks good.

Is there a firewall between the networks? Might be some ports that need to be opened.
