Summary:                    (Regression) Pickup from Grandstream BLF button
ignores the context specified in Pickup command
Description: 
Hi i had problem described in this issue: 
https://issues.asterisk.org/view.php?id=17120
asterisk error was:

[Mar 30 09:48:26] NOTICE[30223]: chan_sip.c:19860 handle_request_invite:
Trying to pick up 520 at blf
[Mar 30 09:48:27] NOTICE[30223]: chan_sip.c:19860 handle_request_invite:
Trying to pick up 520 at blf
[Mar 30 09:48:27] NOTICE[30223]: app_directed_pickup.c:257 pickup_exec: No
target channel found for 520.

I managed to correct it with removing p->callid in line 11302.
I am not a programmer of c++ so I am attaching corrected lines, that
worked for me.

Now phone works like in version 1.6.1, where phone on blinking BLF called
**EXTEN.

urosh, I tested this feature with my GXP2020 and it worked perfectly.  I'm
curious if this isn't resolved or introduced by the latest grandstream
firmware.  The version I tested with was 1.1.4.14, which is very old. July
2007.  What version are you using?  Does it have the "Asterisk BLF"
option?

While setting up the GXP2020 I configured the first multi purpose key to
use "Asterisk BLF" and pointed at the extension of the hint (6001).  When I
attempted to pickup the extension the GXP2020 sent an invite to extension
**6000, which matched my pickup extension, exten =>
_**6XXX,1,PickUp(${EXTEN:2}@extensions).
