If anyone has any questions or feedback I'm very interested. This
configuration has evolved over the past 6 months and is pretty tweaked.
The highest priority traffic in my config, is of course, IAX2.

Router Recommendations Please

Any recommendations on something that isn't as pricey as Cisco? I'm in
discussions about us building Linux units down the line, but for now we
need something we can buy. Cisco is too expensive for us.
TIA!

Is Gigabit Ethernet necessary?
For an office that is using VoIP phones to connect to Asterisk, is gigabit
ethernet really necessary for the Asterisk box to connect to the switch? I
know that I won't even approach the limits of 100 Mbps, but would gigabit
help with latency / collisions when several calls are underway? The fact
is, anything going outside the office will be over a data T1, so intuition
tells me that 100

Linksys RT31P2
Has anyone tried out the Linksys RT31P2 with Asterisk? Seems like a really
great solution for remote users... even supports QoS. Too bad it doesn't
also have VPN functionality built in.
Here's a link to the product:

Solution for 1 time blast of 200, 000 recorded calls
Hi,
I'm helping out with a political campaign and would like to use
asterisk to blast out about 200,000 calls with a short message from
the candidate.
Provider:
I'm thinking voipjet may be a good solution?
Hardware setup:
I will have access to several T-1 lines so I would just want to set up
the dialers to limit the number of concurrent calls and so forth.

QOS Device?
Here is the situation:
A T1 router going into an office which then plugs into the firewall box then
into the switch.
None of these devices support QOS..
Is there some sort of box/device that I can place between the T1 router and
the firewall box which will allow me to prioritize voice traffic on this
link?
I can't change the T1 router to something that supports QOS because it has

QOS / Cisco / Asterisk
We're trying to PQ (Priority Queue) packets on a Cisco using ACL's. What
we're trying to avoid is hardcoding the IP address in the ACL. We were
trying to match by TOS set by Asterisk however it seems we've run into a
snag where the packet TOS tends to get reset somewhere on our network.
Has anyone had this issue? We're running Cisco everywhere inbetween
(even the switches). Is

Dynamically Choose Codec for Bandwidth Management
Is there any way to set Asterisk to choose what codec to allow for a new
call based on current usage? In other words... be able to define a max
number of ulaw calls, then after that only allowing g729? The idea here is
that in general, a T-1 should be enough for our offices to have phone +
citrix + some video (got good QoS in place already). But for usage spikes,
user experience would be kept

destroy SIP channel??
I've got a SIP channel that appears to be hung up. It's an extension that
records a .gsm file and fortunately the recording has stopped. I tried zap
destroy channel but I guess that doesn't apply to SIP channels.
Any ideas? I issued a restart when convenient but figure there must be a
better way.
TIA,

MeetMe & ztdummy
I'm running into a bit of a problem setting up conference calls. The box
I rent at a colo doesn't seem to have USB hardware.... When I try to load
usb-uhci I receive a "device does not exist" error. Which means I can't

The system has a rtc clock module, so zaprtc won't work... (which I'm

Garbled one-way audio only with ulaw
For some reason a couple weeks ago users began experiencing garbled audio
in one direction when dialing out via our VoIP provider. This happened at
multiple sites simultaneously. The VoIP provider doesn't think it's their
problem. If I switch to another codec so that Asterisk transcodes
everything is fine. On conference calls (where Asterisk gets in the middle

RE: small kernel distro recommendations for QoS box
...you want. It
fits on a 64MB flash card but if you install almost anything you will
want a 128MB one. It does come with iptables and iproute2 tools as I

asterisk-oh323 and outgoing call
Hello.
I'm try to set up asterisk for making outgoing calls with oh323 channel
driver version 0.7.1 with Asterisk CVS-1-01/09/05-01:41:37.
Our provider uses Mera MVTS softswitch and supports only H.323.
We don't use gatekeeper for connection but provider requires SOURCE PHONE

Help? Router/Bandwidth throttle needed.
I hope this list is still active. I''m an experienced Linux Sysadmin, but I
haven''t done much in the way of routing. Due to a decision made by my
higherups, I need to jam a computer between my ISP and my LAN to do
bandwidth throttling.
My current setup:

PRIO / CBQ / HTB queue drop algorithm
Hello all.
I''ve been struggling to QoS VoIP at our site and have a successful
implementation at this point. Basically I had to set aside enough
bandwidth for VoIP by placing all other traffic behind an HTB (multiple
classes and queues behind it). Everything is fine. Here''s the diagram:

IAX2 one side loses audio
It seems to never fail - after 3 to 5 minutes SIP -> IAX calls drop
audio on one side. I place a call out through voipjet, and call
quality is flawless. However a few minutes later the person who I'm
talking to can no longer hear me. I can still hear them.
What should I look for to resolve this? Has anyone else had this problem?
Using last night's CVS this problem still exists.

drive space for voice mail
Drive space for voice mail
I've looked in the dimensioning information on voip-info.org but can't
find any hard information on the amount of drive space the various codecs
use. Since we would eventually like to support web-based voice mail
retrieval, I'm thinking of the wav format. I've specced out 2x160GB drives
in RAID-1 (software RAID via Linux) for the box. It will be

PRIO inside HTB - trouble attaching filters correctly?
Hello everyone!
I''m simply trying to put a PRIO inside an HTB (used to throttle). I''ve got
interactive traffic on the network that I want to give priority (VoIP +
Citrix + Video).
I''ve used the filters in a CBQ script fine, but am having trouble
adjusting them to this setup such that they properly assign the traffic.
