[asterisk-users] OT: Best firmware for Linksys Router that is SIP AWARE

2007-11-26 Thread Dovid B
Hi,
I am currently playing with DD-WRT and I like it. I am looking for something 
that is more SIP Aware. Anyone know one those that are out there ?

Thanks.

Dovid - what exactly are you hoping this sip aware firmware will do
that dd-wrt doesn't?  I've been using dd-wrt in combination with
various SIP ITSPs for several years and have had no problems - just
add the necessary port forwards and a few traffic shaping rules and it
works just fine.  I do know that they (the dd-wrt people) have a voip
edition of dd-wrt available.  I'm not sure what additional
functionality it has over the standard version, though.

Erik,

I struggle with the traffic shaping rules, would you be willing to
provide additional details as to what you have done in past?

Any additional information would be greatly appreciated.

Thanks,
Dave

Sure - I use the default HTB traffic scheduler.  The number one tricky
thing about traffic shaping that most people miss is that they don't
set their uplink speed correctly.  For 99% of the use cases out there,
you have no control of your downlink speeds, so there's not a whole
lot you can do for that - you really only have control of your uplink
packets.  So - do a bunch of speed tests and then set your uplink
speed to about 80% of your max upload speed.  That will ensure that
there's always a bit of overhead and that your link itself will never
be the uploade bottleneck.  After doing this, just start classifying
traffic.  Here's a synopsis of the rules I use:

- DNS - high priority
- SIP - express priority
- RTP - express priority
- HTTP/https - bulk priority
- (other p2p applications) - bulk priority

Putting those rules in place should make a big difference.  You can
also specify a specific ethernet jack on the router that will get high
priority if that would help in your setup.

HTH-
Erik
