    Questions:

    1. Why i cannot send fgxes and what i can do to fix it.
    2. read ERROR -1 Input/output error  is something that i can do with that or ignor it ?
    3. Some of the log information (eg. SIP) looks like that : CSeq: 2 INVITE^M <- so it is end character like for windows :/

    I'm not sure if this is your problem but from what I've read, ptlib and opal need to be at svn:24174

    Hi again:)

    Yes, i know thats why I try on the past opal from http://sourceforge.net/projects/t38modem/files/t38modem/2.0.0/

    As i talk with my voip provider they said to me that i have  some problem with SIP signaling and on ACK message t38modem send wrong ip.

    In field "Request_Line" he send  sip:004861823xxxx@sip.freeconet.pl SIP/2.0 instead sip:004861823xxxx@93.159.41.35 SIP/2.0

    Now i  use this script and build everything from scratch but still without success: 

    mkdir /opt/t38modem/ 
mkdir /usr/src/OPAL/
cd /usr/src/OPAL/
svn co http://opalvoip.svn.sourceforge.net/svnroot/opalvoip/ptlib/trunk ptlib -r 24174

    I add here full dump from wireshark

    As we can see after SIP/2.0 200 OK
    with line: Contact: <sip:+48618xxxxxx@93.159.41.35:5061>

    we have ACK:
    ACK sip:0048618xxxxxx@sip.freeconet.pl SIP/2.0

    and i suppose ACK should use information from Contact field.
