Hello, I have a few 3cx setups and they are basically all the same. I have 2 running v10 with sangoma a101de cards along with a pri from carrier. Those 2 have been up for year now no problems. I setup a another 3cx system in our other store, running v11 with same sangoma a101de card. I have it syncd up to pri and calls coming in and out, however after a number of calls, the next one to come in has one way audio? Its always we can hear them but they cant hear us. I have the verbos log below, it clearly shows me calling a few times and getting the voicemail i inteded to get. Then out of nowhere my next call I get dead air, the call completes and goes to voicemail box but I cant hear the voicemail greeting anymore, rtp error. I could really use some help on this, my sangoma card is configured same as my other two 3cx servers, so i dont know whats going on. Thanks in advance!
