[Freeswitch-users] patch for sofia_sip_i_invite to support replaces with action

[Luis Azedo]

Hi,

i need a inline custom action passed with an INVITE msg with a replaces header
or a better to use this scenario.

right now, for calls with replaces header there is support for sla,
intercept and attendant transfer.

my problem is that intercept requires the bridge_uuid which is not set
on one leg calls (on hold playing music) so the intercept condition
won't be hit.

the attendant transfer takes app/data applies and then hangs up the call.

i need a simple answer,intercept:(sip->sip_replaces->rp_call_id)
instead of bridge_uuid.

i tried to set signal_bond and originate_signal_bound on the channel
to see if i could bypass this, but with no luck.

i created a small patch that i am attaching here with the hope that
FreeSWITCH will look and possibly merge it.
