[asterisk-dev] Why does chan_sip disable early bridging???

The reason early bridge was disabled by default (but can be enabled  
in the configuration)
was that it had some pretty large design flaws when used with the SIP  
offer/answer model.
There's no way to signal back what the answering device offers in the  
SDP and in those
cases the call setup might fail miserably. If you test it and it  
works, keep it enabled in
the configuration.

The videocaps branch has some ideas on how to signal back to the caller
properly and this was discussed on the developer meeting in Atlanta, but
seems to have gotten stuck somewhere in the process.

/O
