I installed a new Avaya phone switch along with voicemail. The system consists of the PBX, Voicemail (onboard) and G430 Gateway. One of the features is it has the ability to send voicemail to your email via IMAP. This feature works inside the building but when I VPN into my network the voicemails do not get sent. I cannot also access my PBX through the Avaya software console in the event I had to make a change. Again inside the building is no problem.
I can only assume the PBX, Vmail, and gateway are being blocked by my ASA. I would like to add those three IP addresses to my ASA and normally I have a 3rd part take care of this but they are no being very responsive in order for me to continue my troubleshooting. My question is can someone provide me with the steps on how to add them to what I'm guessing in an access list in the ASA? Please let me know if I need to provide any additional information.
