when i dial in this works, connects me to the sip server and i get audio 
    -- Executing Dial("Zap/18-1", "SIP/siptest|20") in new stack
    -- Accepting call from '613(removed)' to '6260' on channel 0/18, span 1
    -- Called siptest
    -- SIP/siptest-4950 is ringing
    -- SIP/siptest-4950 answered Zap/18-1
    -- Channel 0/18, span 1 got hangup
  == Spawn extension (sip, 6260, 1) exited non-zero on 'Zap/18-1'
    -- Hungup 'Zap/18-1'

i just changed to this
exten => 6261,1,Answer()
exten => 6261,2,Wait(30)
exten => 6261,3,Background(ivrmenu)
exten => 6261,4,Wait(30)

and now i get
   -- Executing Answer("Zap/19-1", "") in new stack
    -- Accepting call from '6138286056' to '6261' on channel 0/19, span 1
    -- Executing Wait("Zap/19-1", "30") in new stack
    -- Channel 0/19, span 1 got hangup
  == Spawn extension (sip, 6261, 2) exited non-zero on 'Zap/19-1'
    -- Hungup 'Zap/19-1'


so its just hanging up after so many seconds has nothing to do with the play
