One way audio in SIP calls via TP Link MR6400
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.
