Abstract:
1. A method comprising: receiving, by a computing device, a Session Initiation Protocol (SIP) request message from an originating device, determining, by the computing device, whether the originating device is associated with a voice-over-Internet-protocol (VoIP) account on a provider network; selecting, by the computing device and when the originating device is associated with the VoIP account, a direct access number assigned to a voicemail system, of the multiple voicemail systems, that services the VoIP account, the direct access number being selected based on a numbering plan area associated with the originating device, the direct access number corresponding to an identifier associated with the originating device, the identifier associated with the originating device being different than the direct access number and being different than the general number, the direct access number being selected to match the numbering plan area, and wherein selecting the direct access number includes: replacing, by the computing device, the general number in the SIP request message with the direct access number to create a modified SIP request; forwarding, by the computing device and based on replacing the general number with the direct access number, the modified SIP request message to the application server; receiving, by the computing device and based on forwarding the modified SIP request message to the application server, a SIP response message from the voicemail system; and forwarding, by the computing device and based on receiving the SIP response message, the SIP response message to the originating device.
