BSNL has excellent infrastructure but is stuck with the old Babu staff that grew up with switch-based telephony tech and due to poor training don't fully understand the newer IP-based tech to which BSNL has migrated. That's why when it all works, it works superb - but if you have any issues, then support takes its own time in BSNL because only the newer, younger generation staff actually know how to fix stuff in the new systems.
