Hi :) I have a little 'slow dialling' problem. When I dial, e.g. 200# for the Asterisk 'echo test' demo application from my PBX extension 1010, I see this in the console the instant I press the # key: -- Starting simple switch on 'Zap/65-1' -- Accepting overlap call from '1010' to '200' on channel 0/3, span 3 then exactly 3 seconds elapses, and finally -- Executing Playback("Zap/65-1", "demo-echotest") in new stack -- Playing 'demo-echotest' (language 'en') at which point Allison's 'sultry' voice announces 'You are about to enter an echo test...' Can I remove this 3 second pause? It's rather annoying, and it doesn't happen when I dial out from the PBX to a normal PSTN line or to a PBX-provided extension, or indeed to any local ISDN2 device. Even with debug + verbose both at 99, I see no extra information I'm using a Sangoma A104u with wanpipe-beta15-2.3.3.tgz and Asterisk/Zaptel/Libpri 1.2.0-beta1. The extensions.conf is trivial [general] static=yes writeprotect=yes [fromaxxess] exten => 200,1,Playback(demo-echotest) ; Let them know what's going on exten => 200,2,Echo ; Do the echo test exten => 200,3,Playback(demo-echodone) ; Let them know it's over Sangoma's support can't understand how it can be their drivers / cards causing the issue since there is no buffering at all in Zaptel (and let's face it that makes sense :) Cheers, Gavin.
