Perform VoLTE Call Using Non-Ascom Note 4 in TEMS Investigation

[rile]

Hi,

I'm currently trying to get TEMS Investigation to initiate a VoLTE call but it is hanging at Dialing.

If I leave the phone in automatic mode (LTE/WCDMA) then I am able to make a call but it is simply doing a standard voice call.

When I lock it to LTE, I get stuck at Dialing.

I did a bit of reading and it looks like I either need to purchase a TEMS phone to use the ODM or manually set the VOIP settings? I'm trying to perform this call using a SM-910T on T-Mobile's network.

Can someone enlighten me?
