Multiple SendDTMF extension in asterisk - asterisk

Question

Good day, I need type extension after dial, I wrote a macros and use it in Dial command, for example:
Dial(Local/123123#outbound-allroutes,,M(sendnum^5^123)
[macro-sendnum]
exten => s,1,Wait(${ARG1})
exten => s,n,SendDTMF(${ARG2})

But sometimes I need type several ext. numbers, how can I do that?
I guessed pass more params in macros at first param is count of IVR steps, and other params are options for steps then in macros process those params in loop, for example:
Dial(Local/123123#outbound-allroutes,,M(sendnum^2^5^2010^6^123)
and macros for this:
macro-sendnum]
exten => s,1,Set(TIMES=${ARG1})
exten => s,n,Set(i=0})
exten => s,n,While($[${i} < ${TIMES}])
exten => s,n,Set(i=$[ ${i} + 1 ])
exten => s,n,Wait(${ARG$[${i} + 1]})
exten => s,n,SendDTMF(${ARG$[${i} + 2]})
exten => s,n,EndWhile
But that doesn't work. Could you please help me? Thank you in advance and sorry for my bad endgish.
