Hi All, is there anyone that tried to work with the t38modem project integrated with SIP through OPAL libraries in OpenSuse 10.2? I followed the cookbook at http://www.voip-info.org/wiki/index.php?page_id=5096 and I've a strange behavior. Firs of all when the t38modem starts, I've an error message that I think is related to some library not present in my current OpenSuse installation (but I'm not able to understand which library is still requiring, if anyone is able to help me to understand what's happening I'll be very happy to hear him). The message is: "error loading avcodec - avcodec: cannot open shared object file: No such file or directory" Running a ldd ./t38modem all seems ok. The next problem arises when I send faxes through an HT386 ATA and asterisk 1.4.20.1. Looking at the network traffic through ethereal I can see that the t38modem answer to the first INVITE message with a 100 TRYING message.. but it never send an ACK. At the same time, the t38modem is producing the log I've attached below (sorry for the long post). Any help is appreciated. Thank you.
