Help Is my phone hacked?

[aakashp2500]

My girlfriend has two numbers, in recent time when she used to call me from her primary number she started getting ringtone, and when calling from secondary number there was no ringtone. Now suddenly she here's the ringtone from whichever number she calls from.

I never have kept any ringtone to my phone. Is it possible that someone has hacked my phone and able to listen my conversation? Please give me solution if so. Need help.

There's usually a ringtone when calling someone, for whatever numbers they're using. Unless the call is diverted, or call waiting, or whatever

Doesn't sound like anything strange going on.
