Question
Users in a company have access to voice calling and voicemail from desktop phones. As the company transitions to remote work, users are utilizing the Cisco Jabber client through Mobile and Remote Access to access company phone services. Users cannot access voicemail through the Cisco Jabber client, even though voicemail is functioning in the office on the desk phone. Cisco Jabber works with IM and Presence, including calling through Mobile and Remote Access. What is the cause of the issue?

Explanation
Mobile and Remote Access (MRA) uses Expressway-C (internal) and Expressway-E (external/DMZ) to allow remote Jabber clients to access internal collaboration services. For voicemail to be accessible externally via MRA, Cisco Unity Connection must be added to the Expressway-E as an allowed external server. The Expressway-E acts as the gateway for remote clients, and without Unity Connection configured there, remote Jabber clients cannot reach the voicemail system even though it works internally. The internal connectivity (Expressway-C and UCM clusters) is already functioning since other services work.
