Short answer = Yes.

Longer answer, it can be a bit complicated. The company I work for (ZipDX) pioneered simultaneous interpretation (SI) over-the-phone about a dozen years ago, at the request of the UN.

Conversational SI allows for a meeting (vs one-way presentation) where everyone can be fully engaged. It allows taking questions from the floor in any language. What follows is a description of how conversational SI works.

You need a professional simultaneous interpreter who works in EN/PL.
There are several audio channels; Floor, English, Polish.

Participants who are bilingual listen to the floor.
EN speakers listen to the EN channel.
PL speakers listen to the PL channel.

Interpreters always listen to the floor.
When the interpreter hears EN they press a button to direct their speech to the PL channel and interpret into PL.
When they hear PL they direct their speech into the EN channel and interpret into EN.

The voice of the original speaker on the floor should be mixed under the voice of the interpreter. This is important to give the audience a sense that the interpreter is tracking the speaker well.

At ZipDX, our system is all VoIP. It can be/has been used with video conference systems. It's not free, or even cheap. Also, professional interpreters can be costly.

Yes, if it's a one-way flow (not conversational) it can be simpler.
