If you are considering moving offices or opening an additional office perhaps in another state then here are the top three things to consider:
Involve your phone system supplier early on in the selection process of the new premises because they may have knowledge about what carrier services are available in a particular building such as fibre, NBN technology, distance from the nearest exchange, if you be crossing Telstra exchange boundaries or charge zones and many other factors. One building may appear to be perfect but if you are unable to get any fast internet capability in it because of distance or the local exchange is full then how would it affect your business?
Your phone system supplier will need time to prepare to move your equipment, install any cabling that may be required, etc. If any internal building is required then this is the ideal time to prewire before the Gyprock sheets go up and the desks go in.
Be aware of the lead times to get your desired services installed. NBN lead times can be very hard to predict as their address information can be inaccurate. This apples to all carriers so it is no good attempting to get a better response out of another carrier.
New buildings may not even have a lead-in cable installed from the street and depending on where this has to be spliced into and the state of the conduit it may take months.
Assuming an existing building with everything in place then the typical lead time can be 20 to 40 working days depending on whether the location is classed as metro or rural.
Depending on the distance you are moving you may need to change telephone numbers and organise diversions of the old ones. In some cases even moving a cross the road will put you into a different Telstra exchange which will require a number change.
If you are with another carrier or use a voice over IP trunk, then these are far easier to deal with and on a temporary basis will work over 4G.
If your listed numbers are 1300’s or 1800’s then this simplifies things considerably because these can stay the same but the real number they point to will change.
