One way audio in SIP calls via TP Link MR6400
Hi there, I have a new TP Link MR6400 – Sip traffic does not work for my home VPN phone or via soft clients. SIP audio RTP is blocked inbound (people can hear me, I cannot hear them). I have tried to disable SPI, SIP ALG etc… all to no effect. I believe this is a FW bug – please advise if there is a new FW or fix for this.
This worked on this carrier with a Huawei B525 with the same SIM and SIP client so this is a router issue.

Below is a beta firmware which you can install it and test whether it works.

If still the same, you can contact the retailer to change another one with newer hardware version, like V3 or V4.
May it help.
