When there is an incoming call terminated to Nortel PABX and which route the call to IPT via QSIG trunk, finally CFNA to VM system. CAller cannot hear the normal voicemail script of his extension grreting, instead the common greeting is provided in VM. At the same time, BUG1008 error appearred in Nortel PABX. We are suspecting something wrong with CLI over QSIG as VM cannot direct to the corresponding extension greeting since no CLI delivery to it.
