one-way audio issue

Howdy all,
I'm currently attempting to set up a DMR/AllStar bridge. Right now AllStar to DMR is functioning perfectly. Where I'm running into an issue is going from DMR to AllStar. I've checked my configs and the ports all appear to be in agreement. Looking at the logs, it appears the audio makes it as far as analog bridge, but doesn't make it from analog bridge to allstar. I believe my issue is on the Asterisk side of things, as I do not see asterisk listening for the TLV frames in netstat. Similarly, running tcpdump, analog bridge is sending out data, but allstar appears to not be listening. Any thoughts or ideas would be appreciated. Connor -- Connor J.

Connor,
The connection between Analog_Bridge and Asterisk is VIA chan_usrp. The data is usrp not TLV. Make sure you have chan_usrp setup. Netstat -unap is your friend.

What do you have in your /etc/asterisk/rpt.conf and /etc/asterisk/extensions.conf for DMR?

Here's the information from the various config files. I pulled just about all of it from the google doc instructions
Host node: 49382 DMR node: 1999 rpt.conf [1999] stanza for node 1999 - https://i.imgur.com/f3sgPoI.png  [nodes] stanza defining node 1999 - https://i.imgur.com/yq5Kl3b.png  extensions.conf node 1999 defined in [globals] and [radio-secure] - https://i.imgur.com/Q8d4fFR.png  modules.conf USRP driver should be loading - https://i.imgur.com/vzFgvOG.png  Asterisk CLI rpt stats 1999 shows as linked to 49382 - https://i.imgur.com/i7y1GRc.png

Steve,
My mistake in thinking that the connection between Analog_Bridge and Asterisk used TLV. In netstat, it appears that asterisk is not listening on the specified USRP port. Just to see, I tried modifying my configuration for the DMR node to use the pseudo driver instead of USRP to see if the ports asterisk was listening on changed and they did. - https://i.imgur.com/NB57yQO.png

including the files themselves is more useful... you also don't have your dvswitch configs included (to look at and match the ports). Just eyeballing this it looks like an extra zero 0 was added to your USRP channel definition... Maybe it's intentional and maybe its not? rxchannel = USRP/127.0.0.1:34001:32001 vs what you have rxchannel = USRP/127.0.0.1:34001:320001 Funny that - you can't hear audio _from_ DMR to ASL.. the port with the extra zero is the port that ASL listens on to receive the traffic from analog_bridge...

Well I guess I deserved that for trying to set this up late at night, then not looking close enough at my configs.
The extra zero in the USRP line fixed it. Thank you all
