I just installed Asterisk 1.4.22 with Asterisk GUI 2.0 for Synology CS-407 (optware). The service provier is Acanac. Most things work great except caller id.
The phone number is dsplayed correctly on extension, but the caller id name is always “New User”. If the phone number is unknown number, then the caller id name is “Unknown”. The issue happens on both ATA+phone and X-Lite softphone.
Then I use Linksys SPA2101 VoIP gateway to connect to the service provider, then both phone number and name are correct.
When I add some commands in extensions.conf to show the caller id interpretted by Asterisk. The caller id name is “New User”. So I think, the issue is with Asterisk itself, not on the extension part.
Any idea how this happened? How to debug this problem? I only worked on Asterisk for 3 days, so I am very new to this area. Thanks.
