Re: Is this even possible?

I spent time today going back and forth with Corey, and he has been most helpful. Since he’s using things not yet intended for general consumption, I’ve decided to hold off until that’s out, and instead focus my attention on simplifying the model so that I can finally get my head around how all the pieces glue together.toggle quoted messageShow quoted text
I’ve spent quite a lot of time today working with IPSC_Bridge and HB_Bridge, and now have the simplest possible setup I could do. I’ve passed audio traffic through from end to end in both directions, but have some issues still.
MMDVM Repeater <-> HB_Bridge <-> IPSC_Bridge <-> K4USD cBridge
So far, it all looks good, but I have a few concerns. Earlier today, I was having a QSO over 8802 via the MMDVM repeater, when it stopped making it through the pipeline all the way to K4USD. I wasn’t able to determine where it was failing, and switched to a direct RF link to a known operational repeater to finish the QSO.
I eventually decided it must’ve been an errant talkgroup from the cBridge, and sent the list of talkgroups I’ve been receiving unsolicited to the cBridge maintainer, and he fixed that when he got home tonight. So now I’m sitting down and testing again.
Just a couple of minutes ago, I heard a ham call out on the 8802 talkgroup via the radio connected to the known good repeater (40+ miles away), but the HT listening to the benchtop repeater had no audio output at all. Everything else looked normal, the pi-star dashboard showed the contact, that TX was occurring, etc. The AnyTone 878 showed the contact information, talkgroup, etc, and updated the last call info after he finished talking.
Here’s the output from IPSC_Bridge:

Now that loss rate from IPSC_Bridge worried me when I first discovered it, but since I was actually passing audio both ways earlier today when it was happening, I figured it wasn’t worth worrying about, probably just mis-reporting. Notice how it’s always 3 out of however many. Always. But now I wonder if it’s indicative of a problem I should track down.
Any ideas what I should check next?
In terms of setting up confbridge, which is preferred to work with, the one in dmrlink or the one in hblink? Ultimately, I want one of those to be the primary decision maker in the “center” of it all. With the link to BM being the most number of talkgroups, I’m leaning towards the hblink one as the one to use.
