Hello experts,The enclosed capture is from an H323 gateway 2811 with 12.4.7 SW. VWIC-MFT-T1 digital E&M CAS trunk connected to a NEC 2000 PBX. There is a problem with failed calls outbound from the 2811 GW to the NEC. I suspect that the NEC Tx wink duration of 128 MSEC is shorter than the 140MSEC non configurable Cisco Rx wink threshold. However half of the calls go through. Any ideas?
