Route Settings
Uni-tel, as most SIP Providers do, doesn't support overlap sending. You must enable the enblock sending of the phone number. You can do this by enabling Force enblock in the appropriate outgoing Route.
The second setting you must check is Interworking(QSIG,SIP). This feature must be enabled to properly relay supplementary services, like Hold over the SIP Trunk. If this check-box is unchecked only basic call Information like connect and disconnect will be forwarded by the Gateway.
