A SIP Trunk is a service where by VoIP calls are routed to and from SIP servers. A customer may have their own SIP Server/PBX, and need a 'SIP Trunk' service in order to make and receive calls though AAISP.
Our VoIP system can simple 'trunk' calls to/from your own PBX - it is perfectly normal for you to have your own office PBX, such as a FireBrick or an Asterisk server for example and for your equipment to provide you will all the 'PBX' type functionally that you require. However, you can also have SIP phones register directly against our servers and use the PBX functionality that we provide. Or, indeed, have a mix of the 2 - e.g. we can route calls to you by SIP (trunk), but we can also record calls.
