Electronic Funds Transfers from any Bank to any ICICI Bank account

I hold some SB account in few banks in India (it doesnt mean that I use it very often or have money in that other than the minimum balance). In that list, I have a ICICI is also there, which is generally used for making my ICICI Credit Card payment, and rarely i use the Debit card branded as ICICI N Cash card. The SB account what I have, is opened some 4 years back in Trichy.

And ICICI bank is one of the first bank in the country to implement Core Banking Solution, i mean 4 or 5 years back. So everyone who has account with them gets a 12 digit account number, which can be used across any of their branch easily for Cheque/Cash deposit or withdrawal. I always give 7 r 8 out of 10 for their service, ie, their service is far more better than many other private & Multinational banks operated in India.

My salary is credited in my CITI Bank account. To transfer money from my CITI account to that ICICI account opened in trichy is not possible as inter-Bank fund transfer list of CITI wont show Trichy ICICI Bank branch. It shows all the bans that participate in NEFT/SEFT in the major cities across the country. So I used to transfer money from CITI account to my friends who have ICICI bank account.

Last month I want to transfer money to my ICICI. Generally I used to tansfer to my friends' account, so that he  will transfer it to my ICICI. In the inter-bank EFT (electronic fund transfer) many of ICICI Bank branch was listed and nothing from Trichy. As ICICI, implemented Core Banking fund transfer between their branches are very easy. So I selected my branch as Cenotaph Road Branch(in madras) in my CITI online transfer page, and entered my 12 digit account numbe and registered as a Payee and transfered some amount.

After two days, I could see that transaction reflected in my ICICI account!! The amount was credited here like a non-listed ICICI Bank account. And I tried this in few other banks like UTI, HDFC & my friend tried in HSBC, which all worked out well.

Im sure this is not a bug, its just a missed option/ unclosed one way hole.
