A new node, 18.104.22.168, was added to the GVGW proxy group today.
A new node, 22.214.171.124, is being added to the Google Voice Gateway proxy list today. If you have a restrictive firewall configuration or specific ACLs, be sure to add the new node to your list.
Our DNS provider suffered a major DNS outage from about 11:30 EDT to 14:30 EDT. During this time, this web site and Google Voice Gateway services were unavailable.
A new proxy node is being added to the cluster and will appear in the DNS SRV and round-robin A records shortly.
If you have firewall rules or ACLs restricting access to your SIP equipment, please add 126.96.36.199.
The rest of the list:

A new proxy node has been added to the Google Voice Gateway (GVGW) cluster and is starting to appear in the A-record and SRV records. If you permitted specific IPs in your firewall or ACL, please note the addition:
The current list:
$ dig +short gvgw.simonics.com. a 18.104.22.168 22.214.171.124 126.96.36.199
The Google Voice Gateway will be unavailable for approximately 30 minutes starting at 1:30 AM EDT on Wednesday, September 23, 2015, for required database maintenance.
Google Voice Gateway was previously stripping the + symbol but leaving the leading 1 on caller ID sent for US/Canada calls. This was non-standard behavior and has been fixed.
Incoming calls from US/Canada will show a ten-digit “national format” caller ID, with name (CNAM) if available.
Incoming calls from other locations will show a full-format caller ID including the + symbol and country code. Name information is not available for international calls.
Starting today, the Google Voice Gateway is able to send SIP calls to your PBX with authentication. If the gateway receives a SIP 401 Unauthorized challenge to an INVITE, it will authenticate using the same username and password your equipment used to register.
This update allows those who are connecting to the Google Voice Gateway with a PBX to tighten their security, allowing calls only from known sources identified by IP address or authentication.
The new feature may be especially of interest to Asterisk users who have had to “allowguest=yes” and handle incoming GVGW calls as if they were anonymous due to Asterisk not being able to properly match peers using SRV or round-robin A records.
In short, to make use of this with Asterisk, set “allowguest=no” and “match_auth_username=yes” in sip.conf, then define your GVGW SIP peer as “type=friend” with the section name matching your GVGW account name. A more detailed tutorial will be available soon in the knowledge base.
I have several providers in my virtual hosting toolbox. One of my new favorites is Digital Ocean, a virtual server hosting company that uses KVM as their virtualization platform and has some great cloud-like features such as snapshotting and deployment from snapshot.
Digital Ocean is my pick for low-latency, high-throughput network and disk (SSD) I/O at a very good price. With VoIP applications, network quality is among the most important concerns. You get a public IPv4 and IPv6 address standard, so there’s no NAT to work around.
Use this link for $10 credit on Digital Ocean and add them to your own virtual hosting toolbox.
We are seeing a significant number of disconnects affecting GVGW users today and are actively investigating the problem.
Thank you for your patience.
UPDATE: I will be upgrading some infrastructure on Saturday early morning (midnight+) to resolve issues seen today. Expect brief outages during the Saturday early morning hours.
Maintenance to the databases was completed and gateways working at 2:00am.
