Rhys Pilott from Peterborough was arrested last year for causing a public nuisance, but was let go early for displaying good behaviour.
Once released from prison, he began making hoax calls again.
Cambridgeshire Police said the 28-year-old dialled 999 and belched at call handlers more than 80 times and was arrested five times.

On one occasion Pilott phoned the force 24 times within the space of 45 minutes, causing the emergency line to become blocked and leaving the service unable to answer genuine emergency calls.
He was arrested again in October this year and was charged with causing a public nuisance – which he admitted at Peterborough Magistrates’ Court, Cambridgeshire Police said.
The force said he was jailed for six months on 23 November this year.
