Have a cust with a 7030, v 4.46d, 10 IP phones, 4 sip trunks. Problem is when a call is placed on hold, there is dead air. Samsung told me to call CommPartners (SIP Provider) and ask them to ignore the REINVITE SEND ONLY. This REINVITE gets sent to the provider when the samsung switches from an MPS channel (SIP Trunk to IP Phone) to an MGI Channel (MOH, Hold, etc..). The only problem is that the provider doesnt know what I am talking about. Was wondering if any of you out there have experienced this. Also curiuos if I can disable the HOLD REINVITE in the SIP options. Will this take care of this.
Also as a note: I can hookup a remote IP phone at my office from the cust switch. I can hit hold and hear the BGM. This just happens on the trunks.
