Headset no longer working on BT VOIP phone since changing Router

[MCrossland]

My BT Router was recently upgraded to a BT Business Smart Hub.  From that point forwards (although I didn't make the connection until today) my Plantronics headset has no longer worked on the BT Polycom VVX 300 VOIP Phone.

As I thought the issue was with the headset I replaced this and the connecting cable but the problem still remained.  I then turned to goo old Google and found out the headest may not be broken and that it may be an issue with the firmware or something else.  Can anyone advise?

Many Thanks
