[Serusers] acc question.

[Greg Fausak]

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 at build.august.net, o-uri=sip:2143357976 at 64.90.42.16:5060, call_id= 847b3d22-131d-46b0-abcb-dc8e6a9f32b5 at 192.168.100.100, from= greg <sip:1107 at 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,
