[SOLVED] No audio incoming calls - outgoing OK - even after re-set - GV
glnz2:
Steve and LTN1 - I ran out and bought a TP-Link TL-SG105 for $19.95.
But what do you think about my first two questions:
As the Obihai 200 is now "out in front" directly connected to the network provided by the mini-office company, and no longer behind my Westell 7500 router, it is presumably accessible by anyone else on this network. What are the real-world risks?
On the one hand, that Westell 7500 router has its Firewall Settings set to "No Security (All Traffic is Allowed)" so maybe isn't doing much blocking anyway. On the other hand, the Obihai was NOT getting an IP address from the network of the mini-office company.Should I now change the "Webpage Admin Password"? of the Obihai 200?

What are the real-world risks? We have no idea. Ask whoever manages that network how it is set up. For example, does each office tenant have their own VLAN on the building's switch? It's a safe assumption that they
have some sort of firewall, but it's up to you to ask.On the one hand, that Westell 7500 router has its Firewall Settings set to "No Security (All Traffic is Allowed)" so maybe isn't doing much blocking anyway. On the other hand, the Obihai was NOT getting an IP address from the network of the mini-office company. Throw that thing out. It's obsolete.Should I now change the "Webpage Admin Password"? of the Obihai 200? Of course.

Steve - thanks again.
My new TP-Link TL-SG105 switch into which is plugged
- the ethernet connection to the internet (the mini-office's landlord's network for its tenants),
- the Obihai200 and
- our obsolete Westell 7500 router
is working and the phone works!
Hallelujah! And I successfully changed the password on the Obihai 200 - to "SteveInWA".
The instructions for the TP-Link TL-SG105 switch are the shortest I have ever seen - just plug stuff in.
However, the box and specs say it offers "Advanced features: 802.1p/DSCP QoS, IGMP Snooping." Have no idea what that does except that I wonder whether it's possible to give the phone connection more priority than everything else. Would the phone then sound 5% better? If yes, how would I turn that on?
As that question might be a bit outside this forum - please just point to some links for QoS for Dummies.
Thanks.

There is no need to keep posting duplicate posts here and on the Google Voice forum. I answered you over there.
PineTree:
I had exactly the same problem starting several weeks ago.
In my case, it was because the Google Voice update a few weeks ago has started using new outgoing UDP ports, and my firewall is set up to block all outgoing connections except whitelisted ones. In particular GV has started using outgoing UDP ports 26500-26501.
The new port requirements are documented here:

Everything works fine again after updating my firewall to allow these ports. No new router required :-)
