Then you can't use ${SIP_EXTENS_0} as the target of a Goto.
Doing Goto(_76XX,10) makes no sense. It might work, but as
you have discovered, you are now in the extension _76XX rather
than the original one dialled.

If you want to do a goto within the current extension, just give
a priority level and nothing else. So do this instead:

exten => ${SIP_EXTENS_0},1,NoOp("Internal Call to ${EXTEN} from ${CALLERIDNUM}")
exten => ${SIP_EXTENS_0},2,GotoIf($["${CALLERIDNUM}" = "7602"]?5)
exten => ${SIP_EXTENS_0},3,Goto(10)
exten => ${SIP_EXTENS_0},5,Set(_ALERT_INFO=http://10.116.4.8/ringtones/darth1.wav)
exten => ${SIP_EXTENS_0},6,Goto(10)
exten => ${SIP_EXTENS_0},10,noop(ready to connect to extension ${EXTEN})
exten => ${SIP_EXTENS_0},11,Macro(transferReturn_sipdial,${EXTEN},20,${SWITCHBOARD})

Cheers
Tony
