SPA-3000 - PBX extension problems

Q: When trying to place a call from the SPA-3000 over the PBX system I get an engaged-style tone all the time.

A: By far the most common problem with PBX extensions is the differences in line voltage between different makes and models of PBX. Changing the setting on the PSTN Line tab of the SPA-3000 configuration called "line in use voltage" to "20" often fixes the problem.

SPA-3000 - Long Line extension

Q: We would like to connect 2 Sipura devices back to back, without a SIP server to make a longline extension.
