VoIP with t-home internet
I try to use my Magic Jack VoIp phone via t-home Internet with Router TM-RTL0102. phone is ringing but audio is one way, i.e. I cannot hear the caller but he hear me. Any thoughts on setup ? Ro...
I had trouble registering to my SIP provider (voip.ms) when initially connecting my Grandstream DP750 VOIP device to the T-Mobile 5G Home Internet Sagemcom Fast 5688W Gateway.
It worked without any issues when connected through another router, which was downstream from the home internet gateway (double NAT).
After further troubleshooting, I was able to get the Grandstream DP750 VOIP device to register with my SIP provider by selecting the NAT Transversal setting (within the profile I’m using → Network Settings → NAT Settings → NAT Transversal) to the “Keep-Alive” option.
Voice audio is working both directions, and other features seem to be working fine as well (message waiting indicator, etc).
