Connecting CCM to Lucent via PRI

Anybody with a lot of Lucent experience. The problem is calls from the Call Mgr to the Lucent G3 via a PRI can connect to a Tie Line in the Lucent but not any other PRI's in the Lucent. Is there any config issues or caveats in the Call Manager that may be able to help this out? I am just looking at all possibilitis.

Re: Connecting CCM to Lucent via PRI

Hey, went through the exact same thing a few months ago. I imagine you're looking for caller-id info, am I right? How are you connecting? Are you going through a router using a High Density voice card, or the DT-24+? Please include your config.

Re: Connecting CCM to Lucent via PRI

Caller ID is working going to the Lucent. Coming from the Lucent I only get the number and no name. I am using WS-6608 T1/E1 PSTN mod. The real problem that we are having is in the Lucent, where the calls coming from the call manager are not able to traverse from one PRI to another to a remote site. Is there any caveats or config issues that may be causing or aggrevating this problem?

Funny, going from our Lucent to the Callmanager, we get both name and number, but going the other way only gives us the number. Can you draw a simple flow of where everything sits and the path you are trying to take to get from point a to point b.

Re: Connecting CCM to Lucent via PRI

When you call from an IP phone to a Lucent phone, the Lucent only shows the number and not the name? Did you make sure to check the "Display IE Delivery" box on the gateway configuration? What version of CallManager, which gateway type? Did you check a CCM trace to make sure there was a Display IE in the Q.931 SETUP message?

Our situation is the digits and name does not show up on the Cisco side from Lucent. Instead it says,

"Unknown Number". Any insight would be appreciated.

Fixed! Config changes done to Lucent and an upgrade of CCM to 3.09.
