Telephone numbers are those numbers businesses utilise to advertise their business. These can be either Inbound Local (eg 03xxxxxxxx), 1300, 1800, 13 Numbers. The type of Inbound number you would use depends on whether you are prepared to take on all incoming charges, just some or none and whether you need advanced features such as Call routing based on regions or time of day, etc. TMC Connect offers all these services as well as international services should you have offices overseas.
