One of the features I use in FreePBX is receiving an incoming call from a landline source and than trasfer it via a SIP ITSP to my mobile, for instance in another country.
In the the Past I used RAPIDVOX that was fully transparent and showed the incoming callerID. Alas they ceased operation a few years ago.
I use now mainly Callcentric but they block any callerID, coming from my machine that is not verified by them. Therfore any incoming call that is transfered to them is anonymous.
Are there any ITSP that enables calleID passthru?
There are legal restrictions on this, in the US, and at least de facto restrictions in most of the Western world, because this feature was loved by scammers and spammers (favourite numbers to pass through were bank and governmental ones, or random numbers on the same local exchange as the spam victim (random to avoid black lists and local to make them think it was someone they knew personally).
Read up on STIR/SHAKEN. There are three grades of number. A where the true originator has been verified. B where the forwarder has been verified. And C, where neither is the case, e.g. a non-US provider. I think there are ways of passing through a number that was received with A grade, but I’m not familiar with the details, and the incoming side would need to be SIP. Simply forwarding caller ID is not enough. People receiving B or C grade numbers may start to ignore the calls.
If possible, send the call to a SIP app registered as an extension – you can send any name and number you like. Look at Sangoma Connect, Groundwire, Zoiper.
Otherwise, try AnveoDirect or Voxbeam. Both provide a small test credit at signup.
Thx for your response. The first paragraph relates to a pre-defined no. not to random incoming calls which is the case.
I will check the advised ITSP
Will a SIP app on your mobile work for you? If not, why?
I cerainly use an application on my mobile. Is saves local call charges. Alas in some countries some operators, it seems that both SIP and IAX are blocked. A year ago I was in Italy using local sim cards. Two out of three operators the application didn’t work. And in Italy mobile calls are very expensive 0.25$ per minute…Some places the Internet coverage is not good enough. Therefore I use a local mobile number as an alternate choice.
I contacted both ITSP
I couldn’t establish connection thru Voxbeam even for testing. Their help desk was very unpleasant and unhelpful. The other one, it seems, is not interested in retail customers.

I managed to connect the Voxbeam server.
Alas, despite configuring an e.164 CallerID in freepbx both extension, trunk and route levels, it ignored it and sent the dialing extension no. and name which was rejected by the server

If that’s not your issue, turn on sip debug, make a call to 18005377950 and post the response from Voxbeam.
