IAX2 Direct PTT issue

KW4KB

I've got a private IAX2 node setup that I use DVSwitch mobile with, I'm super excited about the Allstar and IAX2 feature recently added, updated to the latest beta and RX works fantastic, TX does not work. I can see the audio getting to the remote end, but the PTT signal does not. Anyone else run into this?

Try the Parrot 40894 and another one is 55553
See if you get audio coming back.
Good luck.

FredFeddersen Thank you - I missed that post. Looks similar to the situation I have. My setup I am connecting to is a little unique, it's not participating in the Allstar network. I don't have parrot or other services configured. I use the system daily with a POC device running DVSwitch, when doing a packet capture I see an IAX2 control frame from the POC device but only see the IAX2 voice packets from the M1KE. I'm mobile this weekend but should be home tomorrow to test a little further from the local network. Thanks for the help and directing to the other post.

Please explain what do you mean by the IAX2 control frame. Does your node need key and unkey frames to enable/disable PTT?

As of this morning, with Beta V26 my issue is resolved.

What I was seeing was just a difference I had noted in the packet captures, a type 4 subclass 12 packet was visible on the trace from my POC device, but seemed absent on the M1KE. Looks like some changes in the supported codec with the recent update as well. This is absolutely awesome! Very thankful for the work on this feature.
