A question from the support mailbox:
I'll address the second question first. The validity period is not supported. For the first question... There may be always-on VPN tricks that we have not learned yet, but our current recommendation is that the Android device needs to be on WiFi. NowSMS does not have to be on the same WiFi as the Android device, they just need to have IP connectivity to each other. If they are on the same network segment, NowSMS can scan the network to find the device by name, so it will work with dynamic or static IP addresses. If they are on different network segments, the NowSMS server needs to know an IP address (and optionally a port #) that can be used to connect to the Android device. When the Android device receives an SMS or MMS, it needs to connect back to the NowSMS server to deliver it. This address is not currently configurable, the Android app remembers the IP from when NowSMS server connection, and expects to connect back to port 8990. For off-site modems, we'd recommend connecting them to WiFi with a VPN router that links them to to a common network with NowSMS. We are looking into alternative always on VPN configurations, but at this point you'd need to try your own experiments with our trial version. We have had feedback from one customer that they were losing VPN connectivity because during idle times, NowSMS only polls modems for connectivity issues every 600 seconds (10 minutes). To keep the VPN active, it may be necessary to poll more frequently. This is configurable. In SMSGW.INI, under the [SMSGW] header, add ModemAppCheckInterval=###, where ### is the polling interval in seconds. -- Des NowSMS Support |
