TP Link Issues wtih Phone Stability

Reporting an Issue VitalPBX 4
1

We have just had our third customer now who has had a TP Link modem and had issues with their phones on Vital, but not our old system. Their Yealink phones work perfectly on our previous PBX, yet when we move them to Vital, auto provisioning through YMCS, they register no problem, but their registration changes between green and red (unreachable) and so their phones do not ring.

When we swap out the TP Link for something else, in two cases a Netcomm and one case a Mikrotik, the phones remain green. No issues at all.

This cannot be a coincidence; there must be something with TP Link. There are no firewall settings, all is default, SIP ALG is disabled, still the issue continues.

Does anyone have any experience with this?

I haven’t experienced that however we did move everything over to use TLS to avoid issues. We’ve moved from Poly to Yealink and had issues with Yealink behind CGNAT until we moved to TLS. Poly worked fine for us everywhere.

TP Link is bottom tier for business use in my opinion. Seems like every time we run into issues the customer has either a TPLink or an ASUS router.

I’ve always had great results with MikroTik. Just make sure SIP is disabled under IP>Services.
