Hi. Axon (free edition) has (past tense) been working fine with my 5 extn network - 2 connected by VPN remotely. 1. Getting Error 603 Declined for the past 2 days.... Now cannot get an outside line. Validated that its not a sip account issue as enabled a couple of phones (SPA941) to be on Axon and also have a seperate direct line login to the external sip account. Acccording to Asterisk sites this means the call out is being rejected.... 2. Inbound calls a bit intermittent - can't see anything e.g. errors Only change has been some virus software (Kaspersky) however neither systems seem to trigger anything in the way of errors or events..... Help!
