Hi,
I am trying to create a basic script for routing calls to and from
the PSTN. I have experimented with many scripts over the last month,
this included script is an example. I can use a UA on my
laptop called 'estara' and REGISTER with my ser sip server.
I can make a phone call (INVITE) to the PSTN. I can hang up the call
from either end (BYE) and everything seems to work well.
I am trying to get accounting working. I see the call acceptance
record in my syslog file:
Jan 7 00:21:09 build ser[3507]: ACC: transaction answered: method=INVITE,
i-uri=sip:92143357976@build.august.net, o-uri=sip:2143357976@64.90.42.16:5060, call_id=
847b3d22-131d-46b0-abcb-dc8e6a9f32b5(a)192.168.100.100, from= greg
<sip:1107@build.august.net>;tag=3a7b9c52, code=200
However, I can't get the 'BYE' event to record the transaction to the
syslog file. The 'BYE' event is bouncing through my SIP server.
Can someone give me a hint?
Thank you,
