Hello All,
Thank you so much for the amazing software. I am new to freeswitch and
trying understand how to do the following use case (mobiles):

1. Call is received from LinPhone to User-B
2. Freeswitch (esl code) checks if User-B is a registered user or not
3. If a registered user, forward the call
4. If not a registered user, then send a push notification to the user-B's
5. Freeswitch parks the call from LinPhone user
6. User-B's mobile gets push notification and get's a call screen
7. User-B accepts the call (Actually, he will send an INVITE with the data
received in the payload)
8. Freeswitch receives the invite and should bridge the Linphone user with

I am able to perform all the operations except the last one (Bridging the
call). If I try to use `uuid_bridge`, it says at least one call must be
answered. (*Neither channel is answered, cannot bridge them*.

May I know how to bridge these two legs in freeswitch?

FYI: I have the following park-only dialplan and controlling everything
from esl

<extension name="fspark">
<condition field="destination_number" expression="^(.*)$">
<action application="set" data="bypass_media=true"/>
<action application="set" data="bypass_media_after_bridge=true"/>
<action application="park"/>

Thanks in advance
