IP Trunks

[valencp]

Hello Everyone,
So I have configured and IP signaling group and trunk group between a couple of my locations. Calls made over the IP trunks work well. However, when the IP trunks are either full or out-of-service calls made to the backup trunk group via the same route pattern fail. See screen shot of station trace. Any idea what denial event 1214: Mandatory IE missing means?

This is what I found. Hope it helps...

All this info can be found in the CM 3.1 Document library by doing a Ctrl+Shift+F search for "denial events."

1214 Mandatory IE missing Mandatory IE is missing.
See Cause Value 96 on page 173.
UID DIAG/LOC/CV

Cause Value 96
[0x60/0xE0] -
Mandatory information element is missing
The equipment that sent this Cause Value Call Reference Value (CRV) received a message that
did not contain a required Information Element for the message to be parsed and processed.
Depending on which message in the call establishment sequence is missing information, a
message returned with this Cause Value might or might not indicate a problem establishing a
call.
When the public network is screening for Calling Party Number (CPN), the fact that CPN is
missing causes the network to return this Cause Value, but depending on optioning in the CO
the call might still go through.
This Cause Value has local significance only. The ISDN network between the user and the
equipment generating the Cause Value might:
? Send no cause indication through the network
? Send a more generic Cause Value through the network
