Avaya creates and maintains application notes for certified products manufactured by Avaya's DevConnect Technology Partners. Avaya's application note for configuring an Avaya Session Manager system with a VoIP-2 card can be downloaded from this link.
Be sure to follow the steps on page 10 to configure the CM Endpoint Profile to allow the extension to register using an IP address. The VoIP-2 card does not allow the use of fully qualified addresses, you must configure the system to allow the extension to register using an IP address. (Example: for the VoIP-2 Proxy Username - Room1234@phone.com is not allowed, Room1234 is allowed.)
