Summary:                    [patch] A 'Directed pickup' call is later unable to
Hold or Transfer
Description: 
Specifically: There is code to prevent an INVITE with Replaces: header
while on an existing call.

After a call has been picked up using directed pickup on an BLF button
('magic pickup' not the **extn method), we are unable to place the call on
Hold or to Transfer.

The call just gets dropped.
Asterisk sends "400 Bad request" to phone.

Hardware Grandstream GXP2000 and GXP2010 firmware 1.2.3.5
