Our company has an account in two different ITSPs (Vitelity and Flowroute.)
If I send an outbound call over Flowroute with a Caller ID that’s one of our own DIDs under Vitelity, will there be any technical issues?
No, but there may be commercial ones. A responsible ITSP will not accept caller ID unless they have verified that the phone number belongs to you.
That’s fine, I can prove that at least! Thanks.
