Summary:                    Fetching Call with Grandstream-BLF (**${EXTEN})
Description: 
It is not possible to fetch a call via the Busy-Lamp-Field of a
Grandstream-Phone.

I have 3 phones 116, 123, 202

when i call 123 from 116, the busy-lamp is blinking on the 202. now I try
to fetch the call with pressing the blinking busy-lamp-button on phone
202.

now phone sends "**123" and the call should be fetched. but instead of
this I'll get an error 603.

the same configuration on phone and asterisk is working fine if i use an
asterisk 1.6.1.X

so i had a look at the sip-headers and there's the problem. the 2 stars in
front of the extension are not shown. (see log above)
