Why when we have use Ring Central for Desktop, we can make phone call, but not hear anything. Sometimes, we call several times then we can talk with client or leave message. Please help me check. Thanks
05-08-2017 We had this happening on a few users during the last few weeks, open a Support Case with your Customer Success manager. In our case, they were not able to isolate the cause for this intermittent issue. We have over 2000 users and it has only happened on a few phones if various locations. Our occurences were happening on actual Polycom VVX500 handsets - not via the Desktop. This could be an infrastructural thing at RingCentral as your report would possibly indicate it is not user-hardware specific.
We went through troubleshooting QOS, network port RTP matchups, and network IPs permitted access through the firewall - after doing this with Enterprise support, we still were unable to isolate the actual cause.
