NANPA lists Level 3 Telecom Of California as the company holding the 619-245 block, one of 8 619 prefixes it holds. That is who was given the numbers, not who serves each one today: since number portability, any 619-245 number can move to another carrier and change from landline to mobile or VoIP.
Level 3 Telecom Of California is one of the companies that commonly supply numbers to VoIP and texting apps, so numbers in this block are more likely to be VoIP lines. Only a per-number check confirms it.
