Allow me to edit callback number

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Use a Brazilian carrier that does not store phone number on SIM or that 
stores the 
number in local format 
2. Enable callback
3.Trigger callback

What is the expected output? What do you see instead?
Expected (impossible): get a callback ring
Actual result: my callback never reaches me

What version of the product are you using? On what operating system?
1.1.8

Which SIP server are you using? What happens with PBXes?
Pbxes

Please provide any additional information below.
- Please add callback number override in settings, so I can type my mobile 
number there
- Please, if possible, add another SMS Target: Callback to #, which asks me for 
the number 
to callback to (so I can type the landline near me, as its 8 times cheaper than 
calling back to 
my mobile)

You enter the callback number within PBXes (forwarding on unavailable in 
extensions). 
If you want to call a different number you can use the webcall feature (see 
PBXes forum 
for details on using this feature for triggering callback).
