Hi all, i have been using asterisk for a few years but i am about to do my first t1 setup. After terrible quality issues between two business locations, we have decided to purchase a point to point t1 from the local phone co. The internet is too crappy, too much lag, queing and jitter. Most calls were dropped. I was about to order two cisco routers with csu cards and remembered our wonderful asterisk supports direct t1. I remembered digium and sangoma both make these cards. After some problems with a digium fxo card, i just ordered a sangoma a200 with echo cancellation. I was also leaning towards getting the single t1 sangoma card that is $499 from voip supply. But i know digium also makes one. I was wondering if the digium card works better or much easier with asterisk? The digium description says you can split the t1 for voice and data which sounds nice since i will only be using probably 4 channels max of the t1. Does the sangoma card also do this? I noticed the sangoma card has a 5 year warranty which is nice since i have had multiple digium fxo cards die. Is there any other reason to get or the other? Thank you all for your help. I am hoping this opens up a whole new world in asterisk for me. -Mike This E-mail, including any attachments, may be intended solely for the personal and confidential use of the sender and recipient(s) named above.

We switched to T1(PRI) for high bandwidth & voice quality, echo
I am using TE212P(which is a dual span Echo Chancellor & hardware DTMF). I
have only one PRI connection from PSTN, but I implemented this 6 months agao
when there were no single span cards.
Sangoma just came with one in April, but I didnt wanted to go with that bcos I
havent seen review that the drivers are old but the card is great.
Now when I have a nice setup of PRI with 95 SIP extension to Asterisk. I
recently got A101D(which has Echo cancellor & hardware DTMF) for my standby
asterisk.
Bot of these with their current drivers work great for Echo & Voice Quality.
But my system(config) had a big issue with DTMF detection, which means when
someone calls main line & then trys to punch my extension(123) the asterisk
think its 112 & dials that person or a wrong # like 111 which is not an
extension. SO I had to resolvbe this with Digium by enabling hardware DTMF 6
months ago from software DTMF(I am not sure wthere this was asterisk issue of
DTMF, anyways I enabled hardware DTMF in Digium card & it worked fine.
But now the new Sangoma card which I bough for backup didnt have the drivers
compatible to enabled the hardware DTMF. SO had songoma give me a custom drive
for their hardwrae DTMF & they did within 20-25 days & it works.
But you wouldnt find that driver sin Sangoma site, bcos they are still working
on them(for me they fixed for my model-- A101D)
So in my view both are great unless they work. Atleast I have been using Digium
TE212P for 6 months.
Also note your Network & QoS is also important, we have seperate switches to
avoid QoS it depends uto organisation wish & funding.
Also the type of Desktop VoIP phones you have.
I think I have said lot, let me know if this was helpful or I was just barking
... ha ha ha...
