MR6400 V2.1 not ready for IP-phone?
I have a sole sim based tp-link. With an external antenna nicely working also in difficult conditions. One thing not working: Connecting an external ip-phone. Taking an app like Zoiper, all good. But a hardware based Gigaset, ringing but then the connection collapsing. Any idea from the forum what could it be? Router/ SIM or whatsoever? I´m grateful for guidance.
Best, ruediger10
