    Hi Guys,

    I haven't seen a thread with this particular issue, so I thought it'd be best to ask.

    We've recently installed a new 3CX system at our school. We're currently using iPhones (2 x iPhone 5 & 1 x iPhone 6) for our walkaround phones, however, they seem to be having issues maintaining call connections when walking around the school. We've also tried using the app on an Android phone, which appears to have the same issue.

    While in a call and walking down the corridor. The call will start off clear but will start to lag and then eventually disconnect resulting in the call being dropped. We are currently using a mixture of HP MSM422s & HP E-MSM430s with the firmware version of 5.5.2.1-01-10012 across the board. The iPhones are all connected to the same SSID and are primarily contacting other stationary 3CX phones on the local network. The IPs for the iPhones are all handled by DHCP as well.

    So we just had a couple of questions. Has the app been designed purely for stationary use so it will latch onto one WAP and not handover to another? Is there anyone else who has a similar wireless system who has this working? If so, were there any resolutions to remedy this issue?

    If anyone has any advice or pointers, that would be fantastic!

    On iOS, when you switch from WiFi1 to WiFi2 transition goes like this
    WiFi1->localhost->WiFi2

    If there is a 3G SIM card installed, then transition is
    WiFi1->localhost->3G->WiFi2

    To avoid problems related to configuration (for instance, WiFi1 might be in-office, WiFi2 might be out-of office, 3G always out-of-office) 3CX client drops (well, local drop, since it cannot SIP drop) all calls when existing network changes and reconfigure when the network is available.

    Hi Vali,

    Thank you very much for your reply! It does make sense that the client works that way, so thank you for clearing that up for us.

    I'm assuming this is also the case for Android as well? Just so if there is an alternative we can always use that.
