I think your problem can occur because of SIP Gateway in CUCME config (dual config SCCP and SIP).
Please check your CUE config section: ccn subsystem sip gateway address "10.10.202.1" --> sip bind. mwi envelope-info mwi sip outcall sub-notify end subsystem In the gateway address must appear the ip address you are binding SIP in the router's config, if your SCCP CUCME source address is different, CUE initial wizard puts there the ip address of SCCP server or whatever you instructed. Let me know, it works for me. Thanks, Regards, TITO.
