How do I install and log into the L4 Telcom mobile app?
Download the recommended VoIP or softphone app (we’ll specify which one in your welcome email). Open the app, enter your username, password, and SIP domain, then tap “Register.” You’re ready to make and receive business calls from anywhere.
My VoIP phones aren’t ringing—what should I check first?
Start by checking your internet connection and ensuring the phone is powered on and connected to the correct port. If your internet is working, try rebooting the phone and router. If the issue persists, contact L4 Telcom support for same-day assistance.
My calls sound choppy or keep dropping. How can I fix this?
Choppy or dropped calls usually point to a network bandwidth issue. Try closing unused apps or devices using Wi-Fi. L4 Telcom can also perform a network quality test to optimize your call routing and ensure clear, consistent connections.
Why is there no dial tone on my business phone?
If your phone shows no dial tone, double-check the ethernet cable connection and power source. A quick restart of your VoIP device often restores service. If it doesn’t, our tech team can remotely check your PBX configuration.
I’m having trouble logging into my online phone portal. What can I do?
Confirm your username and password are correct and that your browser is updated. If you’ve forgotten your password, use the “Forgot Password” link or reach out to L4 Telcom’s support team to reset your access securely.
Calls are going straight to voicemail—how do I fix that?
This could be related to call forwarding settings, Do Not Disturb mode, or your PBX routing configuration. Our support team can walk you through step-by-step adjustments or make the fix remotely.
How do I reset my VoIP phone to factory settings?
Hold down the “OK” or “Menu” button (depending on your model) until prompted to confirm a factory reset. Be sure to contact L4 Telcom support before doing this if your phone is part of a shared business system—we can guide you to prevent data loss.
My voicemail notifications aren’t showing up—what should I do?
Check your voicemail box to ensure it’s not full. Also verify your email notification settings if voicemails are forwarded digitally. Our support team can sync your voicemail setup across all devices.
Can I troubleshoot call quality myself before calling support?
Yes. Restart your modem/router, close any unnecessary internet programs, and plug your VoIP phone directly into your main router. If call quality still doesn’t improve, L4 Telcom can analyze your network to identify and resolve interference.
How can I test if my internet connection is affecting calls?
Run a VoIP speed test (you can request one from L4 Telcom). You’ll need at least 100kbps per call and low latency. We can provide a free network assessment to help optimize your call performance.
What should I do if my Hosted PBX system is offline?
First, check your power and internet source. If your network is online, the PBX may just need a quick reboot. If your business still can’t receive calls, contact L4 Telcom Support for immediate remote troubleshooting or on-site service.
How do I add a new extension or user?
Contact L4 Telcom support, and we’ll provision a new extension for your team member, complete with their voicemail, forwarding rules, and permissions. If you have admin access, we can walk you through adding users directly in your PBX portal.
