[asterisk-users] Caller cannot blind transfer

[Marek Greško]

Hello,

I am not sure whether this was correct solution, but I overcommed the
issue by defining context [gosub-stdexten] and including the same
definition of dialplan
exten => xx,1,Dial(PJSIP/xx,30,TtrKk)
exten => xy,1,GoSub(gosub-stdexten,s,1(xy,PJSIP/xy,30,TtrKk))
in it.

It seems the procedure runs in its own context gosub-stdexten. If you
are aware of any better solution I would be glad to here about.
