Hi, We want setup emergency numbers for Australia and Singapore on our PBX. We do have a SIP trunk in Australia and Singapore. We've configured them under (V15.5.5) Settings - PBX Settings - Emergency Numbers. When we tried to dial them we got the following error, <Call to T:Line:10001>>999@[Dev:sip:....sipsg@18....6575.....74.zt.plivo.com:5060] from L:534.1[Extn:007] failed, cause: Cause: 503 Service Unavailable/INVITE from ........:5060> We logged a ticket with Plivo and they responded with the following, "..Kindly note you would not be able to make phone calls to emergency numbers using Plivo ZenTrunk as we use international routes to make phone calls and generally emergency numbers are available only locally..." Am I missing something. Do we need a different type of SIP Trunk for emergency numbers?
