clusters involved in call flow
US, EMEA, SME cluster with ILS
issue: there is an extn(consider ex: 109000) setup as shared line on US cluster, that extn also has an RDP with 3 destinations towards EMEA(for e.g:123456), APAC and India cluster, the call to RDP is through a trunk in SME cluster, it is through the learned DN, When someone calls 109000 and if someone from EMEA with 123456 as shared line answers the call and hangs up the call is shown as "placed on hold"(if the calling party was a VC) for 5-7s before it is actually disconnected, if the calling party was an unified app (call would just show as connected before taking few seconds to hang up). To isolate it what i did is i disabled the RDP to EMEA and applied a fwd all from extn :109000 and then tested the same call flow and this time i wasn't placed on hold, so what i isolated is RDP at fault, but i need to now understand what is wrong with the RDP call flow scenario.
to US cluster extn 109000-> RDP to EMEA extn-> SME cluster-> SIP trunk-> EMEA CuCM
