Re: [sipx-users] Problems with inbound call transfers
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.
Thanks again, Scott for your previous response ..
regards,
