(Anyone) familiar with configuring a Loop Start T1 through a PBX from a
Dialogic card? I've got it to see the T, it talks, it initiates calls,
but they don't connect completely. Incoming calls just ring and ring but
the software shows connection.
Thoughts on troubleshooting?

Hello,
I'm being asked to look into using BFD over our P2P transport links. Is anyone
else doing this? Our transport links are all 10G Ethernet (LAN-PHY). There's no
alarming inside of LAN-PHY like there is in SONET. The transport side should
propagate a fiber break by stopping to send light on

Both. For L2 transport through switches the usefulness is rather
obvious. For WDM type transport because we're

If you are using Asterisk (and many derived PBXs), and your installation is old
enough, and your default context will complete a call...then you may find you
are giving free calling out. This was fixed at some point in the Asterisk
default configuration files.

I should have prefaced that with "older installations" as well. As far as we
can see, most of the newer packages have fixed the known truck-sized holes in
their default configurations, but given the lack of any formal framework for

Hello fellow Nanogers,
I know this is an emotional issue for some but we're looking at some upgrades
to our cores and being a classic cisco shop we're wondering if anyone has had
any experience with the Cisco ASR models in the service provider space. We're
used to running VXR's and are trying

Most/all of the big issues that existed in previous version of
Asterisk/FreePBX have been resolved in later releases.

Hello all,
It has been a while since I posted anything to NANOG. A long time ago
(in a galaxy far far away ;) ) I wrote and maintained a software
package called NorthStar (http://www.brownkid.net/NorthStar) to

Nice to hear from you... we use it every day still ;)
I will admit that we are looking to move to a new system very shortly -
biggest reason is IPv6 support. There are other reasons but that is the
largest missing feature for us by a long shot...
Hope this helps..

I looked at NorthStar about 5 years ago, but due to its lack of support I
chose to use IPPlan instead. I do remember thinking NorthStar would have
been a great solution had you been actively maintaining it, and maybe it
still will -- should you decide to pick it back up.

There are knobs on most models to restrict access to the GUI to:
- the LAN interface
- certain mgmt subnets.
Sounds like the MSO doesn't have things set up correctly.
