International Dialling Weirdness
|
|
| Court Schuett 2005-08-19, 5:45 pm |
| We've got a problem where we have intermittent international dialling
problems. The other problem is that I haven't experienced it and can't
recreate it. What happens is the CIO (of course) tries to dial China.
Three times out of four, he dials and it does nothing. It waits and
then simply disconnects without error.
I have tried many times to recreate this and I cannot. I am also not
local so I am relying on third hand information. We have proven that
international dialling does work. It works for me when I try to call
around and sometimes it works for him.
There is a 10 second interdigit timeout that seems a bit long. Could
turning that down perhaps help? Also, he is using a 7970 phone and I
have found them to be quite unreliable.
Does anyone else have any other ideas? I'm a bit stumped here.
Thanks!

| I thought the same thing, but there is only one Route Group it is
assigned to. And only one PRI on that Route Group. (Actually it is an
H323 gateway). There is only one way the call would be going out. I'll
try the DNA anyway though.
Thanks for the ideas. Anymore? ;)

isdn q931" and ask the CIO to place some calls to China, then analyse logs
and speak to telco?

| I'll try that, but the problem is that it doesn't sound like it's even maki=
ng it to the gateway. The other problem is that the calls always seem to g=
o through ok, so I'm not sure it is with the Telco.
Thanks for the input! =

fails.
