[Asterisk-Users] Any ideas why I can't dial this SIP phone (sometimes)?

[Matt]

Can anyone offer any insights as to why with one of these examples I
can do a dial to the sip hone, and with the other I can't?

DOESN'T WORK:
    -- Executing Dial("SIP/109-d35d", "SIP/101|5|tr") in new stack
    -- Called 101
    -- SIP/101-c9ff is ringing
    -- Nobody picked up in 5000 ms
    -- Executing SetCallerID("SIP/109-d35d", "Xfer Andrew <109>") in new stack
    -- Executing Dial("SIP/109-d35d", "SIP/116|30|tr") in new stack
    -- Called 116
  == Everyone is busy/congested at this time (1:0/0/1)
    -- Executing Goto("SIP/109-d35d", "andrewvm|1") in new stack

WORKS:
-- Executing SetCallerID("SIP/109-5107", ""Xfer Andrew VM" <109>") in new stack
    -- Executing Dial("SIP/109-5107", "SIP/116|30|tr") in new stack


    In both cases, SIP/116 is on hook and available for calls.
The only thing different is in example one... before it rings
extention 116, it rings extention 101 for 5 seconds.
