Since I changed my SIP provider, I have following problem :
When I get a call from a external SIP line and take them on hold,
the the caller will here the message on hold from my SIP provider and not my MoH configured in my SPA9000.
When I take an internal call on hold, the caller will hear my internal music.
It seems that the MoH message will be sent out to my SIP provider which overrides my MoH music.
How can I disable this in the SPA9000 to do not sent out this message ?
