2 sites, both IP500v2, R9.1.9, 9608 sets. Valid Voice Networking license in each. SCN only seems to be somewhat working ONE WAY. Both sites have programmed an IP Office Line, Proprietary, SCN, unique Line group ID. Site A was installed first with VM Pro. We then added Site B and then needed to move VM Pro to site B (because they are a busier office, more AA use, more mailboxes, call recording, etc. Also if VPN went down, site A could live without voicemail where site B could not). When I established the SCN, in system status it show up and idle on the channels. I could dial from site A to B, but not from B to A. I then added a short code in B (2xx, dial, 2N, LG of SCN). With the short code there, I could dial across. I also noticed that the name/groups of A did NOT appear in contacts of B, but all of system B's users/groups appeared in contacts of A. Then finally, when I when to put Voicemail Pro at site B, I made all changed, site B was set to Voicemail Lite/Pro with local server IP address and site a was set to Centralized with LG ID of SCN. None of the users and groups of site A appeared in Voicemail Pro. However, site A could access voicemail from the phones! So strange. Anyone ever see anything like this and/or have any thoughts on what the issue could be? Currently, I have each site running on its own VM Pro.
