[asterisk-users] Pickup cmd

[Rilawich Ango]

Hi all,
  I have a GXP2000 with BLF configured.  I follow the configuration
guide to enable the pickup cmd as follow and include it under
corresponding content.

[BLF_group_pickup]
exten => _**1XX,1,Pickup(${EXTEN:2})
exten => _**1XX,n,Hangup

The I press the single key to pickup the call to extension 100 when
there is a call to it.  From CLI, I can see it issue **100 to asterisk
but failed to pickup the call.

    -- Executing [**100 at internal:1] Pickup("SIP/102-08373480", "100")
in new stack
[Dec  7 16:47:42] NOTICE[31079]: app_directed_pickup.c:159
pickup_exec: No target channel found for 100.
    -- Executing [**100 at internal:2] Hangup("SIP/102-08373480", "") in new stack

Anyone can tell me if I make something wrong for the pickup cmd?
asterisk version: 1.4.15
