Long distance (Hawaii-Boston) Asterisk setup help
Submitted by ehsoftware on Thu, 01/10/2008 - 2:19pm.
Our small (10-person) company has offices in Hawaii and Boston. I'm having a lot of trouble getting an adequate Trixbox setup working. Here's what I'm attempting:
* One Trixbox to maintain (I'm testing with Lylix right now)
* One reliable VOIP trunk provider (testing with Teliax, want to avoid POTS lines)
* One incoming toll-free line, extensions for each user
* Users at each location can dial users at other locations via extensions
* Users can easily switch between locations and keep their extension
* Traveling employees can easily use Softphones
Here are some problems we've run in to:
* Unpredictable call quality (generally latency + quality is great, but it tends to degrade unacceptably during long conversations. We don't use the phone that much but when we do we want it to be solid.)
* Having trouble getting DTMF tones to register reliably
* Both offices are behind NAT and phones appear to lose registration from time to time (we have lots of cisco 7940s + 7960s)
We have fairly good connections at each office so throughput shouldn't be a problem. But Hawaii and Boston are very far apart - am I just being unrealistic in my demands?
BOTTOM LINE: I'd like to hire someone to help troubleshoot our situation and put together a plan of action (or who will advise us to suck it up and set up local Trixboxes). Thanks!

Hi
no matter what, use two trixbox boxes linked with iax, you'll solve a lot of problems, i had many times your situation and solved it with iax. Do the people using softphones from outside use iax ones, like zoiper(good one with pro version also with g.729).
pm me for more info and advices.
cheers

Are you recording calls
did you run top and watch the cpu / memory
I messed around on a VPN link from three different datacenters to Hawaii (the big island Kilauea volcano monitoring stations), the company wanted to add VOIP / video conf to the remote stations; that was back two maybe three years back.
No matter who we used here or the customer used there it was a no go.
same datacenters we use with links to most counties in the world without issue.
The links would fade way during peak hours from 7:30 a.m. to about 10:00 a.m. and in the afternoon from 4:00 ~ 7:30 p.m. (hawai time) we could count on crap calls and lost of tunnel's between the two.
ping times would go from 150~200 into the 1000's for 10~30 seconds at a time or just timeout.
If was as if the whole island was using the same pipe to the US
I think those folks gave up and went telco for phones.

Hawaii IP isn't the best, you might want to get a provider that can get you a T1. PTP T1s to Boston are expensive ~$1,700 - so if you can use it for other than VoIP. We have 55Mbps and use a provider in N.CArolina, latency is about 120ms. Our Oregon provider is 80ms. its really the jitter you have to watch out for too...
Also, can you put 1 Trixbox in front of the NAT ? you can put it online with a firewall infront of it, just NAT really hurts - especially when both sides are natted. OR get a public provider and have both your triboxes register to the public guy.
anyhow - hopefully you got your issue fixed.
