[Freeswitch-users] Bypass_media mode

[Mark Campbell-Smith]

Hi Jason,

I have understood that.  Its not that a difficult concept to understand!

In the log I see:
2010-01-12 21:03:17.585598 [DEBUG] mod_dptools.c:818
sofia/internal/1000 at 192.168.1.120 SET
[ringback]=[v=-7;%(400,200,413,438);%(400,2000,413,438)]
2010-01-12 21:03:17.605591 [DEBUG] switch_core_session.c:1509
Application tone_detect Requires media! pre_answering channel
sofia/internal/1000 at 192.168.1.120

I thought the SIP re-Invite message can be used to update media
parameters, including IP address endpoints.  Does FS try too do this
in the case that tone_detect is used?
