CUCM, Nortel via H323 trunk Connected Names

Unanswered Question
May 6th, 2009

I`m trying to set up a network between the two system CUCM 6.1 and Nortel Option 11 TDM. The trunk is all set up and working however the issue is with the calling name on connection. After much testing I`ve configured the following

On the Nortel connected GW

Voice Service voip

qsig decode

Without this commend I was only seeing one way name and number- when calling from Nortel to IPT the Nortel details name, Number appeared on the IPT and when IPT to Nortel the IPT details Name, Number, appeared on the Nortel phone - not both way

and on the Serial port of the same GW under the Interface Serial x/x/x:15

isdn supp-service name calling

In addition I had to tick on the H323 the CUCM connects to

Display IE Delivery-

if this was turned off but isdn supp-service name calling was left on then from Nortel to IPT, the Nortel details Name, Number appeared on the IPT phone but from IPT to Nortel only the number appeared

Testing- with the above configured

Calling from IPT to Nortel Phone

Both names appear on each other phones on calling but on connection the IPT phone changes from Name and Extension Number to Extension number only

Calling from Nortel to IPT Phone

Only the IPT phone see the Nortel extension Number and Name on calling again on Connection it drops back to number only as above. No details are sent to the Nortel

Any ideas
