Hi, With 3cx v11, does the combination of 3cx phone for iphone and 3cx tunnel for iphone work? Or is that combination only for 3cx v12? I have the tunnel, and I have the 3cx phone for iPhone version for v11 - but the phone doesn't seem to know the tunnel app is there. The tunnel successfully connects, but the phone flips back and forth connecting in office and connecting out out of office (which is disallowed anyway), unsuccessfully. On the server, I can see the tunnel connection in the router and log, but no sign of the phone. The phone is provisioned with the provisioning file, and I've also tried manual, but no luck. The router is configured for the tunnel UDP and TCP. 3cx phone for iphone for 3cx phone system ver.3.0.41 gives me: "Connecting out of office" "Out of office request time out" "connecting in office "In office request timeout" Should it work? Thanks, Les.
