Dear List,
We are having FreeSWITCH behind AVAYA infrastructure and when FreeSWITCH sends a BYE the From and the To headers are inverted. For example this call was initiated by John Smith however the BYE request has the From and To inverted:
send 619 bytes to tcp/[10.125.15.122]:5060 at 16:57:04.079105:

These seems to work for Cisco and other Telephony products but not the particular AVAYA system we're working with.
Is there any way to modify this behavior and/or is this a known issue?
Thank you so much
