Bit of a different question, has anyone been able to use the DSS keys on the Yealink SIP-T2x phones as extra MWI's? I know I can do it on Cisco phones but don't really want to have a lone cisco in an office of yealinks. I just want to have two separate mailbox indicators on the DSS key. I tried just registering the two accounts to it but it always use the main MWI key rather the DSS. Is it possible?
