Subject: Colorado reaches 91% rural broadband coverage as efforts to
improve internet for Ute Tribes move forward
By Tamara Chuang
One look at Colorado's official broadband map and Bernadette Cuthair
will tell you it's wrong.
As the Ute Mountain Ute Tribe's director of planning & development,
Cuthair has been working to help her community access faster internet
service. But the current broadband map makes it seem like the
southwestern town of Towaoc, the base for the tribe, doesn't need
help. The map shows most of the town already has federally adequate
speeds of 25 megabits or faster.

Back in the 1700s copyrights lasted for 14 years with one renewal, but since
then they've been extended past the point of absurdity. Since 1978 the rule
has been 70 years after the death of the author for works written by people,
or 95 years for works written by corporations and other legal entities. For
software, it might as well be forever.

Assuming SIP protocol:
If you could record the IP packets, for example with tcpdump or
Wireshark (available also on Microsoft software), you may see something
like this: an attempt to RE-INVITE the session on a private IP address.
If you have this option on your IP phone, try to disable reinvitation.
This may, or may not, be the problem, but a Wireshark capture (first a
simple PNG capture of the exchange, with sip in the filter area,
then sip || udp, would help).

This looks like: SIP session establishment work, but the RTP / UDP audio
path does not work immediately.
What SIP phone do you use?
Did you try another SIP provider?
Do you have special SIP NAT traversal options on your router?
