Hi,
1.4.10 with polycoms 550.
when I get an incoming call (PRI) i pick up… i hit transfer i dial extension (lets say 1022) I announce the caller to 1022, i hit transfer again… the call is transferred to that extension, but the person @122 does not know that the transfer was sompleted. Is there any way to send a beep or something like that, so the person knows that I hung up and he/she is on line with the original caller?
xfersound = beep in features.conf does not work…
thanks
help… anyone? 
The way you are doing transfers uses the function built into the phone. If the attended transfer facility of Asterisk is used by setting up a key to use in features.conf then the called extension will hear the default beep on transfer. I had exactly the same problem myself.
I have feature set to use 5 so when speaking to the caller I key 5 then get a dial tone, caller hears MOH as you would expect. When you have anounced call you hang up, called ext gets beep then call.
Hope this helps, I am not an expert by any means.
Mike.
