[cisco-voip] RDNIS and Original Called Number IE

[Jason Aarons (AM)]

You can use TCL to preserve the RDNIS across a PRI that doesn't support Redirecting IE.  Search this page for RDNIS.  You need a cisco.com login. This is a difficult task but can be done. Both far and near end gateways need it, usually I dedicate a inbound DID just for SRST with this on the Unity side that matches the SRST side's call-manager-fallback voicemail number.

In my experience with this all providers from the remote site to the Unity pilot  location ALL need to support RDNIS, which is not always feasible.
It's been a while but I would look into sending the digits inband

We're running CUCM 8.6(2).21900-5.

When one of our remote sites goes into SRST, I would like to be able to have voicemail survivability by forwarding no-answer/busy to the Unity pilot number at our central site.  We're using DMS-100 PRIs at both locations and I can see in the ISDN debugs that the redirect number is getting correctly passed by the telco in the ISDN Setup Original Called Number IE.  CUCM however is not passing on the Original Called Number IE contents to Unity Connection.  I have "Redirecting Number IE Delivery - Inbound" checked on the GW config, but that's not the IE that's being used in the Setup; I assume that's because it's a DMS-100 PRI.

The remote GW is SIP so as an experiment I tried forwarding a call there. This GW correctly takes the contents of the Original Called Number IE and puts it in the Diversion Header which CUCM uses as the RDNIS so it looks like I have a problem with my central MGCP GW.

Am I missing something in my configuration, or does CUCM not support the Original Called Number IE?

Thanks,
Eric
