How to troubleshoot no calls in or out on my NEC PBX?
If your NEC PBX system is unable to make or receive calls, first check the router configuration and the NEC PBX configuration. Also, note the WAN IP address and contact your provider to ensure it is qualified.
Why are my calls dropping on my NEC PBX?
If your NEC PBX calls are dropping, it could be due to internet access issues, extreme latency on the LAN, or a SIP issue. Contact your internet access provider and check the latency on your LAN. You may also need to contact your provider regarding the SIP issue.
What to do if my NEC PBX has no calls out?
If you are experiencing issues with making outgoing calls on your NEC PBX, first verify the NEC PBX configuration. Additionally, note the WAN IP address and contact your provider to ensure it is qualified.
What to do if my NEC PBX has no calls in?
If you are not receiving incoming calls on your NEC PBX, start by checking the NEC PBX configuration. Also, note the WAN IP address and contact your provider to ensure it is qualified.
Why are parts of words missing on my NEC PBX calls?
If you're experiencing missing parts of words on your NEC PBX calls, it could be due to packet loss or latency on the LAN or WAN. Check the LAN and consult with your internet access provider to check the WAN. Also, check the Jitter Buffer Configuration with NEC.
How to fix echo on NEC PBX?
If you are experiencing echo on your NEC PBX calls, it may be due to excessive delay or an echo cancellation issue. Check the LAN and WAN for high latency. Also, check the echo settings and/or consult IDT/Net2Phone.
