Summary:                    [patch] app_directed_pickup: No target channel found
for extension, Worked on 1.6.0-rc6
Description: 
Before upgrade from 1.6.0-rc6 to trunk. Directed pickup worked well.

Now we are getting:
[Feb 27 22:06:51] NOTICE[27187]: app_directed_pickup.c:255 pickup_exec: No
target channel found for 8510.

After replacing pickup_by_exten with function from tag 1.6.0.6-rc6 I was
able to find that the dialcontext and context were never going to match.

some debug below: with 1.6.0-rc6 version of pickup_by_exten 

[Feb 27 22:39:20] NOTICE[1465]: app_directed_pickup.c:273 pickup_exec:
context=BLF_Group_1.
[Feb 27 22:39:20] NOTICE[1465]: app_directed_pickup.c:217 pickup_by_exten:

---------------------------------------------------------------------- 
The grandstream was using subscribeconext to pickup the call. In our case
the subscribecontext was BLF_Group_1.

debug output from patched app_directed_pickup.c:
app_directed_pickup.c:217 pickup_by_exten: macroexten= exten=8510
dialcontext=trusted context=BLF_Group_1 canpickup=1

Removing subscribecontext from sip.conf allowed internal calls withing the
same context to be picked up, but calls started from a different context
IE. 'incoming' and ringing a phone in the same context 'trusted' as the
phone that wants to pickup to ringing extension will fail.
