HI, In my serial forking configuration I have this problem:
if i use the a media gateway ( asterisk ) on the same machine ( but I
see also on the another machine) of openser ( on the 5061 port) I have a
problem with the timeout of a call. The call continues beyond the
timeout and when by the PSTN telephone I reject the call appears the
following log message:
Warning: sl_send_reply: I won't send a reply for ACK!!
Where I have mistake? Any idea?
Another thing. I see that I redirect the call directly in the media
gateway, (for example a location of a user is a PSTN number) whitout the
traslation of IP number, all is ok.
