Ok, I finally got myself enough time to try and resolve this problem, and have made some progress. I have attached the ngrep output, but from my understanding of it it seems the topex box is not handling the SIP refer (required to transfer a call) being sent to it from sipx server .. although the topex box accepted the refer, it then turns around and was unable to complete it.
Well, thats my understanding. Would appreciate a second opinion. One secondary effect I have seen is that calls that have been affected this way, remain hanging for hours and days on the sipx side (when you list active calls via the web GUI). Its like sipx has actually contacted the destination extension number (albeit without ringing the extension) and is waiting for the topex side for confirmation before it would hand-off the call to the destination extension. If at this stage the topex side fails (as seems to be happening), sipx seems to have no way of stopping the transferred call from being registered in the system. I am just speculating here based on my observations, and relative inexperience of sipx. BTW, is their a CLI way I can list active calls in sipx ? Also, any CLI commands to terminate active calls ? Relying only on the GUI can be cumbersoome and inconvenient in some situations.
