We currently operate an MKC Communications Server for our small
company. We have 4 offices across Canada and calls to our toll-free
number are answered by our VOIP server and directed by the auto
attendant in the server office to the 3 satellite offices. This system
works well except we have intermittent quality of the calls, sometimes
losing connection altogether, but usually garbled speech etc. The 3
satellite offices are behind firewalls on adsl or cable high speed
connections. We cannot get much support from MKC and I wonder if
Asterisk would be a better system for this. Is this a problem because
of the wide geographic area being covered, and so more router hops?
Unfortunately as long as you are relying on the internet at large to
deliver calls, routing can be an issue.
There are things you can do to improve this, however.
1) Use a codec that is as compact as possible (usually G729), less
data to deliver means less chance of it being broken along the way.
2) Make sure your routes are as smooth as possible. This might mean
using the same ISP where possible and verifying there routing within
there network is better then what you currently have.
3) If you are using "shared line" technologies (this can be with ADSL
or Cable modem), usually going to a dedicated line can help. Still
there is no promise this will help. Analyzing your issue is really
step 1.
I am sure there are other ideas here on the list to help your
situation, but asterisk is not going to be a magical bullet for
internet routing issues.
Asterisk is however MONDO flexible and can give you many options with
regards to which technology you use to receive and call out.
Good Luck,
Marty
