I have been setting up multiple nodes and bridges on a Vultr cloud server.  Currently I have:

1)  ASL to DMR Bridge -   Working correctly -  I have made a contact thru a <Handheld>  <Pi zero Hotspot > <Brandmeister> <Cloud Bridge> <ASL>

For the next two, the exact same issue is occurring.   Using DVSwitch Mobile, back to the Cloud Bridges, they will register ok - USRP - Enter a <BM> talkgroup,  And TX on the talkgroup correctly.  My issue is there is NO return audio from the bridge.  I have triple checked the setup files to ensure no port issues.  Logs indicate that transmission of data to/from Analog Bridge and MMDVM.  Currently, there is no firewall running so all ports are clear. 

2)  DVSwitch Mobile to DMR (Add YSF and ASL In the future)

3)  DVSwitch Mobile to DMR (Add YSF and ASL In the future)

I have (1) Instance of Asterisk running, (3) Analog Bridges, (3) MMDVM Bridges, (3) MD380 EMU's.  The reason for the (2 & 3) is one for myself (n0mgj), one for my father (n0ebb).

Is there something that I am missing?  My only thought is that I need to change the ports to/from asterisk for (2 & 3).  Although this was not referenced in the howtos that I have been using. 

Below is a diagram of all three with ports, etc.  I can post all of the specific files if necessary, I have modified all the directories for each instance, etc.  

Any Pointers?

Thanks in Advance
