Data centre SIP Trunking
SIP Trunking replaces telephones lines in an internet telephone system. Conventionally, the telephone exchange (PBX) is on the user’s premises. It is connected to the public telephone network (PSTN) on ISDN or analogue telephone lines. In an internet voice telephone system, the PBX is in a colocation data centre, which also hosts suppliers of SIP Trunking. The PBX connects to the PSTN via SIP Trunks.

Scalability of SIP Trunking
SIP Trunks can be almost immediately configured or removed. So you can have as many or as few telephone lines (channels) as you need. Extra telephone lines could be added for a summer telesales campaign, then removed when it completes. Voice operations can grow easily with the business or reduce easily if needed.
Number Flexibility
Telephone numbers can be moved around the country at will. For example, you could move offices to a different town, keep the same numbers, lose no calls during the move and have no need to change the stationery. For business continuity and disaster recovery, hosting your PBX in a data centre where SIP Trunking suppliers colocate with you means you can move to emergency premises without losing calls, changing numbers or anyone outside even knowing a move has taken place.
Fewer Lines, Lower Cost
Multiple offices each have multiple PBX’s and telephone or ISDN lines. Bringing those PBX functions into a single internet PBX based in a colocation data centre hosting SIP Trunking providers reduces the number of lines needed. Using SIP Trunking in a data centre reduces the lines and the cost.
Voice and Internet Convergence
Voice and internet broadband are the same thing in the internet world. Little bandwidth is required for voice compared with broadband internet access. There is no longer any need for separate connections to the user’s premises – only a single, diversely routed broadband connection back to the colocation data centre where the PBX and the SIP Trunking providers are hosted.
