Digital Phone ringtone is choppy and stuttering
I am using a vtech digital cordless phone connected to my modem TEL1 port. The ringtone sounds choppy and stuttering and isn't the full polyphonic ringtone that I set on the handset. Instead of a full cycle of ringing, it sounds more like a half ring or quarter ring.
Calling it from different phones produce the same choppy ringtone. Changing to other ringtones (basic or polyphonic) doesn't solve the issue either.
Searched online and discovered that other users have reported similar issues that remain unresolved so far. The problem could due to the current from the modem is not strong enough to support a full ringtone. Please advise.
