[center][/center]TDM800P CDR always shows ASWERED even if it was NOT answered

Hello are some days I am trying to solve this problem.
My configuration is:
TDM800P card with 1 FXO and 4 FXS ports
elastix 2
the problem is:
when I call from a sip client to another sip client ( extensions ) in the CDR database is correctly shown when the call was answered or not.
When I call from a SIP client to the outside PSTN via the line connected to the FXO port, all calls are in the ANSWERED state, below a piece of log:

1. 2008-04-30 15:02:47 SIP/105-b6... 105 "alessandroportatile" <105> 0335xxxx ANSWERED 01:11
the above call was NOT answered by my cell phone

I tried also tho change the parameter answeronpolarityswitch=yes in ZAPATA.CONF but the result is exactly the opposite, all calls are UNANSWERED and also a line containing an "s" in the DST column is added with the same time stamp instead of the called number.

This is my ZAPTEL.CONF

# Autogenerated by /usr/sbin/zapconf on Thu Apr 24 14:39:09 2008 -- do not hand edit
# Zaptel Configuration File
# This file is parsed by the Zaptel Configurator, ztcfg
# Span 1: WCTDM/0 "Wildcard TDM800P Board 1" (MASTER)
# channel 6, WCTDM/0/5, no module.
# channel 7, WCTDM/0/6, no module.
# channel 8, WCTDM/0/7, no module.

# Global data

loadzone = us
defaultzone = us

Do I have to change loadzone and defaultzone to IT since I am in Italy?

Please help me to solve this problem because is essential for me to know WHEN a call is answered for correctly billing calls to my customers. I deeply searched into the forum and outside but the only tip I found is the ANSWERONPOLARITYSWITCH as described above.
Many thanks in advance for the help
Best regards

Hi Mehmet,

Actually its highly dependent to your Telco, you can enable callprogress in your zapata.conf but on analog lines there is no gurantee for suitable functionality. If your telco supports polarity reversal signalling on answer and disconnect then answeronpolarity is useful otherwise not.
