Hello,

I’m using event socket outbound and have a framework that does stuff based on the events that come back (this includes my own IVR). What I have now is an IVR system that allows 2 users to bridge to one another at will, and to ‘unbridge’ at will by catching DTMF events.

I have 2 requirements:
<![if !supportLists]>1. <![endif]>When one leg hangs up during a bridge, the other leg is presented with the IVR
<![if !supportLists]>2. <![endif]>After a bridge, when one leg sends a DTMF tone, both legs will be presented with the IVR and no longer be bridged (they can bridge with other sessions again after this point if they desire)

I have done multiple experiments by using netcat and 2 sessions. Here is what I have found:
<![if !supportLists]>· <![endif]>The hangup_after_bridge variable does nothing for me. I’ve set it on both legs, but whenever one leg hangs up after a uuid_bridge, the other leg will automatically hang up

<![if !supportLists]>· <![endif]>I’ve tried setting “park_after_bridge=true” on both legs, and this works to a certain extent. If one leg hangs up, the other leg will be parked, and I can present that user with my IVR. This meets requirement #1. However, requirement #2 won’t be met because:

<![if !supportLists]>o <![endif]>If I set “park_after_bridge=true” and one leg sends a DTMF tone to signal an unbridge, I will “unbridge” the legs by “parking” both legs and I am able to present them both with an IVR. If they decide to bridge with each other again (by selecting an option in the IVR), I will attempt to do a uuid_bridge and this will FAIL! (both parties do not hear each other.) In the simplest terms, I can’t do “uuid_bridge uuidA uuidB”, “park”, “uuid_bridge uuidA uuidB”.

<![if !supportLists]>· <![endif]>With “park_after_bridge=false” (default), I can do “uuid_bridge uuidA uuidB”, “park”, “uuid_bridge uuidA uuidB” with no issues, meeting requirement #2. However, this will not meet requirement #1, because when one leg hangs up, it will trigger a hangup on the other.

Please help. How can I meet both of my requirements?

Thanks.
