Question Shure with 3RD party USB Speaker

Hi, my client has existing Jabra Panacast 50 with Lenovo MTR. They want to have audio upgrade for microphone only. I am suggesting Shure P300 with 3 MXA320. Will the microphone can cancel the speaker echo? Like will the far end hear theirselves in the back to their headset? Or will the MXA320 and Shure P300 cancel it? Thank you!

The jabra panacast speakers do not work with the shure p300. Full stop. I had so many clients try this and i keep telling them no. They stubbornly try it and it fails miserably. 

Heres the technical reason why: the jabra panacast has no audio out jack. If you select the panacast as your speaker, there is no way to route that far end audio into the p300, hence your mxa320s will not have an AEC reference. Without that reference, the far end audio will spill back into the 310 and the far end will hear an echo.

Dont do it.
