Troubleshoot outgoing call problems. For Physical line customers. C
Don't worry. If calls will not connect, the cause is often the number dialled, a handset left off hook on a digital line, or outbound call barring on premium, directory enquiry, or international numbers.
Quick answer
Confirm you can make a test call, or note if you hear engaged tone before dialling.
Step-by-step checks
Confirm you can make a test call, or note if you hear engaged tone before dialling.
If engaged before dialling: restart the router and cordless bases, re-seat every handset on its base.
Make a short test call first. If that fails, See No dial tone
Dial a UK mobile using the full number including area code. Wait a few seconds after the last digit.
Try a different phone plugged into Phone1 on the router.
Note whether incoming calls still work when reporting.
Still not working?
If outgoing calls still fail after these checks, report a fault online with what you tried and which numbers fail.
