We have just setup a QSIG link between new CUCM 7.1(3) and Nortel Meridian Op.81 using MGCP gateway. The problem we have - there is no caller-name information coming across from CUCM to Meridian. The other way around - Meridian to CUCM - caller name is shown all right. Also we have an old CCM 4.1 connected to the same Meridian using QSIG over MGCP gateway. In the case of calls from this CCM 4.1 to Meridian the name goes across all right. When you trace the call from CCM 4.1 to Meridian you can see a Facility element going across (where I assume the caller name is). But the similar trace for the call between CUCM 7.1 and Meridian does not show any Facility element going from CUCM to Meridian at all. So I wonder if we need to do anything special in CUCM 7.1(3) to enable sending out Caller Name across QSIG link in MGCP configuration.
By the way, if you go to CCM 4.1 MGCP configuration of the link you can see that some tick boxes are ticked there by default: Display IE Delivery, Send Extra Leading Character In DisplayIE, Setup non-ISDN Progress Indicator IE Enable. If you go to the same configuration page in CUCM 7.1 the same settings default to "Disabled", the tick-boxes are not ticked and greyed-out.
Thanks for the help.

|ASN.1 ROSE OID Encoding and Calling Name in setup msg using PRI QSIG.|
Outbound calls over QSIG gateway fail
supplementary services like calling name, connected name, callback etc.. fail
CUCM 7.X and higher
QSIG configuration :
Serviceparameter - QSIG variant = ECMA
Serviceparameter - ASN.1 ROSE OID Encoding = ECMA (GLOBAL)
Gateway - QSIG Variant = No Changes
Gateway - ASN.1 ROSE OID Encoding = No Changes
Configure on gateway
Gateway - QSIG Variant = ECMA
Gateway - ASN.1 ROSE OID Encoding = ECMA (GLOBAL)
Further Problem Description:
With the configuration documented under conditions, CUCM will encode the Facility/Rose Invoke as ECMA / Local while it is expected to be ECMA / Global. (as configured on the remote PBX)
Depending on the remote PBX configuration/type the call will get released or Rose Invoke will get rejected.
