Is it possible to detect if an incoming call has been forwarded from another number?
My scenario is:
- I have a SIP trunk set up in FreePBX at home
- My work mobile phone is forwarded to my SIP number
- All landline calls from our office have caller ID withheld.
- Someone calls my work phone from the office, which is then forwarded to FreePBX
- I normally reject calls without a caller ID, but I need to answer the ones coming from work.
