I upgraded to the latest version 5.0.3790.0 recently and all went pretty smoothly. However, after the upgrade I noticed the following: The caller display on our SIP enabled phones is showing “Linksys Gateway” on the display when we are receiving an external call rather than the caller ID as it used to do before we upgraded. The one other weird issues was that I had to change the registration settings for our PSTN line under 3CX-Manage Gateways and Providers->Registration Settings->to Require Registration for Nothing as I could not get the PSTN line to work with the old SPA3102 settings after the upgrade. Can anyone help with regard to the caller ID issue? I can live with not having to force a registration for the PSTN line…unless this is important! I only included this as I thought the two issues might be linked! On the 3CX server I can see the incoming caller ID being displayed in the server status. I have made sure that the setting: PSTN CID For VoIP CID: is set to Yes and I have an answer delay on the PSTN of 3 seconds to give time to pickup the Caller ID. Any help greatly appreciated.
