No, you need to use the "Local" channel type. So as not to confuse
between labels I'll use a different name for the contexts. So in
extensions.conf you might have something like this:

[internal]
exten => _1XXX,1,Dial(SIP/${EXTEN})
exten => _1XXX,2,NoOp(DIALSTATUS=${DIALSTATUS})
exten => _1XXX,3,Hangup

[external]
exten => _X.,1,Dial(SIP/${EXTEN}@provider)
exten => _X.,2,NoOp(DIALSTATUS=${DIALSTATUS})
exten => _X.,3,Hangup

Then if you wanted to dial your internal extension of 1234 and
when answered connect them to the outside number 0123456789,
through the manager API you do the following:

Action: Originate
Channel: Local/1234 at internal
Context: external
Exten: 0123456789
Priority: 1

See http://www.voip-info.org/wiki-Asterisk+Local+channels for more info.
