Local culture apparently dictates that is acceptable, indeed even mandatory, when making a telephone call, to ignore the other party's courteous salutation ("Hello, Wolfdog here!") and immediately interject with "HOOZISS?!" a very forcible interrogative expression with no fewer than eighteen syllables in it which my orthography may fail to fully capture.
→[More:]Etiquette also requires that any further polite volleys ("Who's calling, please?") be batted down with further abrasive questioning and willful incomprehension ("IZZIS DUBYA DEE? HOOZISS?") and, in the face of unsatisfactory responses ("No, you have the wrong number") no fewer than three further attempts (*ring* "Hello?" "HOOOZIYUSSS?") will suffice to indicate due diligence in contacting the intended part (DUBYA DEE or CHA-YUD or whomever it may be).
Rustic though it may be, I do not find it among the most endearing of local customs.
