Nesting Variables in Asterisk dialplan

Hello experts,

In my asterisk dialplan, when user dials extension 1, sip trunk (GSM1) should be dialled, and an email should be sent to (Email1) address. The same with extension 2,3 and 4

I wrote this in my dialplan:

[gsmplan]

exten => _[1234],1,dial(SIP/siptrunk/GSM${EVAL(${EXTEN})},60)

exten => h,1,System(/usr/local/bin/sendEmail -f me@domain.com -t Email${EVAL(${Email1})} -m 'This is a test message' )

In the verbose, I am having:

Executing [1@gsmplan:1] Dial("SIP/user-0000064b", "SIP/siptrunk/GSM1,60") in new stack

The problem is that it's dialing GSM1 while it should be replaced with it's variable value.

Any help?

Do you mean that you have a variable called GSM1??

If so, you have made two mistakes. First, the GSM must be within the EVAL brackets. Second, you are trying to use the Dahdi device format as the first argument to the Dial command, for a SIP call. SIP calls use a slightly different format for that first argument - for details see the section "Using the Dial Command with SIP Channels" at this link:
http://www.voip-info.org/wiki/index.php?page=Asterisk+SIP+channels

Try this:
    exten => _[1234],1,dial(SIP/${GSM${EXTEN}}@siptrunk,60)
 ...or this
    exten => _[1234],1,dial(SIP/${EVAL(GSM${EXTEN})}@siptrunk,60)

Thank you for your helpful post ! I was waiting for your response :)

Actually this worked perfectly:

exten => _[1234],1,dial(SIP/${GSM${EXTEN}}@siptrunk,60)

But this didn't work:

exten => h,1,Set(emailDest=${EVAL(Email${EXTEN})})
exten => h,2,System(/usr/local/bin/sendEmail -f me@domain.com -t ${emailDest} -m 'This is a test message' )

In console, I am getting: Set("SIP/gsmgw-00001184", "smsDest=GSMh")

Here are two problems: GSM and h.

Thank you in advance.

Sorry for the mistake, the verbose is:

Set("SIP/gsmgw-00001184", "emailDest=GSMh")

Try this....
If you accept this as part of your solution, please make sure Feptias get's points and best answer.

exten => _[1234],1,dial(SIP/${GSM${EXTEN}}@siptrunk,60)

exten => _[1234],n,Set(numdialed=${EXTEN})

exten => h,1,Set(emailDest=Email${numdialed})
exten => h,2,System(/usr/local/bin/sendEmail -f me@domain.com -t ${emailDest} -m 'This is a test message' )

Wait... sorry I meant to reverse the first two lines...

exten => _[1234],1,Set(numdialed=${EXTEN})
exten => _[1234],n,dial(SIP/${GSM${EXTEN}}@siptrunk,60)

exten => h,1,Set(emailDest=Email${numdialed})
exten => h,2,System(/usr/local/bin/sendEmail -f me@domain.com -t ${emailDest} -m 'This is a test message' )

Remember that ${EXTEN} always evaluates the current extension....
