Will Micollab works in LAN only mode iphone clients? When I try to deploy the Micollab in LAN only mode, the client in Iphone shows soft phone greyed out. I did not build or plan for the MBG, because the customer needs micollab only while in office. I checked with Mitel TS and they confirmed that Micollab doesn’t works only in LAN mode and MBG in DMZ or network edge is mandatory. Does anybody here has Micollab working only in LAN mode with no mbg for Iphone clients?
