One of the companies I consult with currently has 6 POTS lines to their office. The POTS lines connect to a server running Asterisk with a Digium card. Most of the people work remotely and have Cisco IP phones that connect over the office’s not so great DSL line. I’d like to move their Asterisk offsite (onto a server in a datacenter, or VPS somewhere) but the issue is the phone lines.
Has anyone ported their phone numbers over companies that do SIP or IAX trunks? The key for the business is to keep their same numbers.
