To resolve the issue of the voicemail system not routing calls between Cisco Unity Connection and Cisco UCM via SCCP, verifying the registration of the CTI ports is necessary. This is because CTI ports are essential for SCCP communication. If these ports are not registered, the call control between the systems will fail, leading to issues such as users being unable to check voicemail.
