We're looking to configure a UC560 with a SIP trunk over a Site-Site VPN to a Mitel 5500 (to run latest version 5). This is purely for site to site calls via internal DDI's.
Having a quick hunt round I see a few brief items regarding Cisco CME to Mitel kit but they are generally older documents.
Can anyone help provide config examples or confirmation of it working / setup documents and guides perhaps from Cisco?
Any help or advice appreciated.
