Customers provisioning their own hardware devices should be aware that a special dial plan is needed to use our service effectively. Without the correct dial plan you may experience delays of up to 20+ seconds before hearing a ring tone when making outbound calls. The following dial plan is effective on all Sipura and Linksys* devices.

The correct dial plan to use is: (Important: Copy and Paste these into one string with no spaces or line breaks)
([3469]11|0|00|[2-9]xxxxxxxxx|1xxx[2-9]xxxxxxS0|*xx
[2-9]xxxxxxxxx|*xx|xxxxxxxxxxxx.|[2-9]xxxxxxS2L2|*xx
[2-9]xxxxxx|*67[0-1]xxxxxxx.)

The entire string above should be pasted into the dial plan box as one line. After you save the update, the delay problem should be resolved immediately.
