No doubt India has different names, which we use them even today. India, Bharat and Hindustan all are the same. Similarly, Belgaum(now renamed Belagavi) went through different name changes ever since the Ratta Dynasty started ruling this place.
Below are the names it achieved in the past history.
Jirnasitapura – Old Belgaum and Shahpur, the then Sapur were together called Jirnasitapura in the 7th Century. [ Reference Pg 138 of The Indian Antiquary ]
Vamsapura, it got this name when Queen Gunavati got a offspring from King Kuntamaraya. [ Reference – Pg 140 of The Indian Antiquary ]
Venugrama or Velugrama or Ikshugrama was the name in 805 AD [ Reference – Pg 862 of Karnataka State Gazetteer]
Venugram in 1199AD [ Refrence – Pg 862 of Karnataka State Gazetteer]
Azamnagar [ According to Mr. Strokes (Belgaum, 45), after the fall of bijapur, the fort of Belgaum remained for several years in possession of Aurangzeb’s second son Azam and from him was called Azamnagar. This seems doubtful.
