It has been held recently in case of Bharathi telecommunication & othrs by the Delhi HC that the interconnection charges, port charges etc paid does not fall under the technical services as it does not require any mannual intervention. The same position would also apply for the dedicated lease lines as well. The provisions of 194I could not attract for these transactions as for renting a property, equipment or machinery one has to have a absolute control / pocession over the same which is missing in the case of lease lines. Moreover in the case of lease lines the same cable would be shared by many customers and therefore it cannot be teated as rent payments under income tax act.
Normally the hiring of vehichle would fall under 194C but after the ammendment to the definition of sec.194I the hiring of vehicles could fall under 194I as well.
Therefore to conclude the intention of the party has to be seen. If it is only for movement of the goods/person from one place to another and the vehichle is in the control of the person who gives it on hire, ie. he appoints his driver and fuel and maintenance is taken care by the owner of the vehicle it would be u/s 194C.
If you take pocession of the vehicle totaly (by operating it yourself or with a driver appointed by you) and pay the owner for the usage hours of the vehicle, or the kms you drove it, then it would be under 194I.
