[Serdev] BYE gets lost with call from Messenger over isdngw

[Ulrich Holeschak]

Hallo,
now after the CSeq BYE problem has been fixed, i found a new one with BYE, but this time i thinks it's more a problem in ser.
When i call a PSTN phone with isdngw from Windows Messenger all works well, but the BYE in both directions gets lost (disconnect from Messenger or Phone). If i look in the log file i could see (In this case it's a disconnect from the phone):

You could see the error:
    ERROR: tcp_blocking_connect: SO_ERROR (111) Connection refused 
    ERROR: tcpconn_connect: tcp_blocking_connect failed 
    msg_send: ERROR: tcp_send failed 

Something goes wrong here, what could that be?
This only occures if the call is made from Windows Messenger!

Thanks,
Ulrich
