I have setup a PSTN Gateway using a Linksys SPA3012. I used the instructions for the Sipura 3000 on the 3CX site to configure the SPA 3012. It registers fine and I can send a PSTN call out through it from a softphone or the analogue phone on the SPA3012's Line 1. However, I cannot seem to be able to recieve PSTN calls from the SPA3012. All I get is "CallConf::Rejected: Call (C:B) is rejected: Caller is not allowed". I have tried some of the advise from other posts with no luck. Has anyone got this configuration working? If so what is the trick. I'm currently running Beta 5 on a new installation. I had the same issues on Beta 3 & 4. Many thanks.
