Apparently, we have been implementing Cisco SRST feature at one of our site using Call-Manager-Fallback mode. And below is our Alias configuration example:
alias 1 1800 to 1864 cfw 1827 timeout 16
alias 2 1800 to 1827 cfw 1811 timeout 16
alias 3 1800 to 1811 cfw 1897 timeout 16
alias 4 1800 to 1897 cfw 1800 timeout 16
What I was expecting to happen is if a call is received on 1800, it will FIRST be routed to 1864. If it's busy or not answered within 16 secs, it will be routed to 1827 and so on. But, what I have found is the SRST router routes the call based on the extension which was REGISTERED FIRST with the SRST router (or may be random??).
What I am trying to achieve here is, ext. 1897 should only be receiving calls if all other 3 extensions are busy or not answering.
Could you please advise me if this can be possible?
I don't think using "Preference" keyword on alias command would make difference because that can only be used if I have more than one dial-peer for the same destination-pattern (extension) which in this case I don't.
Also, I don't want to use "Call-forward busy" and "Call-forward noan" commands because that will forward calls from any registered extension, not only from the hunt-group.
Also, I was wondering if the SRST router has the ability to queue the calls? What happens to the next call if every extension in this hunt-group is busy on other call?
I am using Cisco 2851 router with 3.3 Ver of SRST.
Your help will be much appreciated!!!
