Is a PBX used?

- If yes, call WebWay support. - We will reconfigure your SPT remotely, adding a “9” prefix to the called number.

Has the REN value been exceeded?

- Check how many devices are installed on the PSTN line. - If there are more than 4 devices (rule of thumb), advise the customer that the REN may have been exceeded. Options - Remote a device from the line to enable the SPT to communicate. - Order a new line to cater for the additional equipment. - Alternatively recommend the end user switches to broadband.

Is the line from BT?

Non BT supplied PSTN services may introduce latency (delay) to transmitting signals, effecting the operation of the SPT. - Call WebWay technical support. - We will reconfigure the device to enable BT as the carrier selection (if supported by original provider). - Alternatively recommend the end user switches to broadband.
