We currently have a H323 3845 ISR gateway with a MGCP QSIG interface connected to an Ericsson MD110.
When we were running CUCM 7.0 we had calling and called name presentation between both systems however since upgrading to CUCM 7.1(2b) we are not receiving the alerting/called name when CUCM calls Ericsson. However once the call is connected it is then presented. Ericsson to CUCM works fine.
The QSIG Variant in the Service Parametres is set to ISO and using ASN.1 ROSE OID of Local Value which is now also set on the interface of the gateway since CUCM 7.1.
anyone got any ideas on why its behaving like this??
Any suggestions will be appreciated.
