Hi, ZAP/DAHDI extension 3210 calls an Asterisk queue 4050 with one SIP agent 4053 added via ->QueueAdd("4050", "Local/4053 at from-internal/n", 1) (not via agents.conf). SIP extension 4053 rings, answers and then decides to blind-transfer to ZAP/DAHDI extension 3666. The "show queue" command still displays 4053 as "In use". However, if 3210 calls 4050 and 4053 answers and finally hangs up (no transfer) then the "show queue" command does not display "In use". What's the difference? # asterisk -rx "show queue 4050" -- Remote UNIX connection 4050 has 0 calls (max 6) in 'ringall' strategy (1s holdtime), W:0, C:1,A:1, SL:0.0% within 0s Members: Local/4053 at from-internal/n with penalty 1 (dynamic) (In use) has taken 1 calls (last was 99 secs ago) No Callers Verbosity is at least 3 # asterisk -rx "show channels concise" Zap/2-1:from-alcatel-custom:s:1:Up:Bridged Call:Local/4053 at from-internal-4120,2:4053::3::Local/4053 at from-internal-4120,2 Local/4053 at from-internal-4120,2:macro-dialout-trunk:s:19:Up:Dial:ZAP/g1/3666|300|tTwWM(auto-blkvm):3210::3:122:Zap/2-1 Local/4053 at from-internal-4120,1:from-internal:s:1:Up:Bridged Call:IAX2/coinbound-1551:3210::3::IAX2/coinbound-1551 IAX2/coinbound-1551:ext-queues:4050:19:Up:Queue:4050|t||:3210::3:128:Local/4053 at from-internal-4120,1 Verbosity is at least 3 Thanks, Vieri
