NO...
its called connection bridging... which is not available...
to my knoledge... by so far...
Only ISP and service supports this service is BSNL ISDN... i have tried all other available connection in my area (Kolkata).. none of them supports it..
try asking their customer care about connection bridging... none of the customer care exicutive have any idea about it.. and if by channce one do get some idea what u want to do.. u will get reply... "Its Illigal"...
any configuration in response will work
now u r talking... yes there are many available.. but very few in india... and they are very costly too... mostly what i know is widely use product are Cisco... they prodive hardware to get load balacne and do what u r asking for... if u by chance get few hardware, they are very costly...
