Volume button on iPhone 7 does not have any affect on speaker volume, when I am in conference and other person continuously speaking over the call.

Steps to Reproduce:
1. Join a Conference as a participant. 
2. Turn On speaker Mode of phone, so incoming voice from other party is via speaker.
3. while listening to other person via speaker, press the volume up/down button and listen to other party's voice.

Expected Results:
The phone volume setting should have impact on the speakerphone operation i.e iPhones Volume buttons up/down press should increase/ decrease the volume coming out of speaker.

Actual Results:
The phone volume setting has no impact on the speakerphone operation.
I could listen the voice of other party equally loud even I lowered the volume fully and vice versa.
