Can someone clarify the enclosed VPM debug capture

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?

Re: Can someone clarify the enclosed VPM debug capture

Hi, seems to me router is not seeing a signalling change at all, can you check show controllers t1 for slips and errors ?

Also, if you want to try changing timers, that is "timing wait-wink " under voice-port.
