I've got a TG200 with the 4G module. SIM card is connected to my local LTE carrier.   How to get the HD voice over SIP out of it?  All codecs available are just 8kHz ones. Does this gateway support HD voice?

  Hi, good question, I have also problems with this device.

  I try to use voice over LTE, the TG200 is registered in the LTE network, but if there is an active call, we have always only 2G (GSM) connections.

  I use the vodafone network from Germany.

  Which network / country did your TG200 use for active calls?

  It does not really matter if there are no codecs that can handle HD

  Also, SPEEX is 8Khz too

  Correct for your issue, but why is it not possible to use 3G or 4G for active calls?

  Can you check this on your device and mobile provider please?

  mine falls back to 3G when a call is active. Perhaps VoLTE isn't fully supported
