The 5 main benefits of SIP Trunking
The difference between SIP and Hosted Telecoms
SIP is best suited to larger SMEs and mid-market organisations to ensure they can benefit from the increased flexibility and security provided by SIP Trunking that a Hosted Telephony solution cannot offer. When you compare SIP to ISDN it often works out cheaper on a per channel basis, it’s more flexible in terms of what telephone numbers you can have and where you can have them and is quicker to install.
Another advantage of SIP is that it also provides a very robust business continuity service to ensure your business never loses calls. Calls can automatically fail over to backup analogue lines connected to your system, or to mobile devices. Unlike ISDN, DDI’s can be forwarded to different destinations at network level. They can also be configured (depending on your PBX) to failover to a secondary internet connection.
