 Update on TA612V
I have made progress on the problem. The TA612V is primarily attached to a cable or DSL Modem. By using a cross over cable to connect it to my wireless broadband and port triggering the voip ports (outgoing 5060:5060 incoming 10000:20000) I was able to hear when using the phone but no one could hear me. I thought this was due to a total drop off of upload speed as although the download speed stayed the same as when the broadband was attached to my original router the upload speed dropped to 2% of what it had been. By reducing the MTU size on the TA612V to 1436 the upload speed returned but there is still no outgoing speech. Port forwarding the outgoing port has no effect. |
