[Freeswitch-users] _sofia_replaces_ from hangup_hook

[Isaac Jurado]

Hi,

Given the following scenario:

    X calls Y  (channels A0 inbound and B0 outbound)
    Y calls Z  (channels A1 inbound and B1 outbound)

Then, if Y performs an attended transfer, B0 terminates with an
ATTENDED_TRANSFER hangup_cause (or endpoint_disposition).  However, A1
does not show any special sign of beign part of the transfer operation
except a CDR variable named "_sofia_replaces_".

The problem with that variable is that it doesn't appear as part of the
"env" object in Lua hangup hooks.  Nevertheless, it appears in the XML
CDR.

What's happening here?  Am I doing something wrong?

Cheers.
