[Freeswitch-users] Showing caller number

Hi there,
 so, basically, you want to fake the outgoing CLI. ISTM that this is NOT a freeSwitch problem.

freeswitch -could- send a different caller ID when outcalling, but you're using some supplier to call out to the mobile via the PSTN.
Typically, that supplier will either trust that you "own" the calling number you're presenting (customer provided network screened),
or will not want OfCom jumping up & down on their head and so put what they believe is your number in the SS#7 message they send
to the mobile operator in the outcall (network provided calling number).
Note that the supplier is supposed to at least screen whatever number you provide. It's their responsibility.

Given that OfCom tends to be unhappy with people faking calling numbers, this is a hard problem.

=> I suspect that it is not something that freeSwitch can fix with UK based outcalls.

best regards,
 Lawrence Conroy
