Good Afternoon,
I am currently trialing 3cx for a client for use with a bespoke application but I am experiencing several issues that i'm hoping someone can help with.
The Setup is as follows,
A 4G router and Android Tablet running a bespoke application has been installed at several remote locations. The application includes Linphone which is configured to register using TLS.
At the head office a Yealink T58W including camera module has been installed, connectivity has also been provided via a 4G router. The Yealink has been tested with both UDP and TCP sip signaling,
The 4G routers do not have a fixed IP Service, SIP ALG has been disabled on all devices. An external aerial has been installed in an attempt to acquire the best signal,
No SBC is configured.
I am experiencing the following issues
On the Yealink device I am experiencing Intermittent registration issues, I appear to of overcome this by disabling STUN on the Yealink device by manually configuring the extension and not auto provisioning. i'm not sure if this introduces more problems.
The other issue is that I am seeing issues with video, the stream can freezing for up to 30 seconds multiple times per call but not every call, audio appears to be unaffected. This issue has been witnessed on both the tablet and Yealink device, only one device experiences the issue during the call and the issue can affect either the caller or callee . After reviewing the 3CX Yealink T5x provisioning guide and implementing the suggested configuration for TCP transport I am still experiencing the issue. From reading the user forums I assumed this was because of NAT issues with the LTE network but I have been able to replicate the issue using test devices on the Office Wi-Fi.
Any advice would be greatly appreciated.
