It depends on your PSTN termination company.

Some let you set CID to anything, some to any DID you rent from them, some 
not at all.

You should ask them what format they want/allow the CID specified -- how 
many digits, country code, punctuation, etc. If you don't follow their 
format, all bets are off.

Thanks in advance,
