[Users] forward_reply error

[johnk at koreanet.us]

Hi all.

After UA makes a PSTN call, if remote PSTN peer hangs up first, server
correctly receives BYE from gateway, hit BYE section in config and CDR
records accordingly through radius.
But if UA hangs up first, BYE section in config never gets hit, instead
server logs "ERROR: forward_reply: no 2nd via found in reply" right after
" ACC: transaction answered:...", which was logged when the call was
answered by called PSTN.  CDR accounting only records without STOP time
and duration being zero.

Any comments will be appreciated.
