SPA IP Phone - * (Star Key) not working using 3rd party conference service

Question

Hi - I have an SPA 504G  with SIP service and use a third party conference service to host conference call.  The 3rd party service requires me to log in as the Leader and to do this I have to press the * key.  This doesn't work possibly becuse * has been configured as a short action code.
Does anyone know of a way to disable short codes (*) whilst a call is in progress?
Thanks

Answer 1

This doesn't work possibly becuse * has been configured as a short action code.
Then deconfiguration of such action codes and/or relevant supplemental services should solve your problem.
It may help you to know that I have no problem using * against remote IVR with the following configuration (SPA508G with firmware 7.5.4):
