[Asterisk-Users] Line Noise HELP!

[Paul]

Damian,

 

pbx*CLI> show version

Asterisk CVS-HEAD-03/23/05-00:44:07 built by root at pbx on a i586 running
Linux

 

There is my version info. Someone on the list has suggested that it's my
SIPura phone. It could very well be the phone, but it just seems unlikely
that the conversation would be perfectly clear for some time before the
static starts. I tried it today and was able to go approximately two minutes
before it started. The FXO card is a generic x100P. I'm going to try to get
another IP phone and test it to see if it's the phone. Let me know if you
come up with any ideas.

 

Paul

Hi Paul, there was a thread yesterday in regards to a few of us experiencing
a very similar problem - a problem that (if the same for all of us), doesn't
seem to have been properly diagnosed yet.

 

One thing that appeared to be common to all of us was the version of
Asterisk that we are running (1.0.6), is this the version that you are
running?  What FXO card are you using?

 

Does the noise that you are complaining about occur on every call and, if
so, always after exactly a minute, or is it more random?

 

Starting to wonder if there isn't a problem with Stable, interested to hear
what version you're running.

 

Damian.

I recently hooked up my sipura IP phone and set it up as an SIP device to

connect to asterisk. I am able to dial a number on the SIP phone, connect to

an external number via the PSTN connected to asterisk and begin the

conversation. At first, the audio quality is PERFECT, in both directions. I

can hear the person clearly and they claim to hear me like im on a regular

POTS line. After approximately 1 minute, the quality turns horrible and the

person can no longer hear me, but I can faintly here them. There is a lot of

static on the line, it almost sounds like an electronic device is

interfering with it. I thought maybe it was a wireless phone or router, so I

disconnected all those and put my cell phone in the other room. Still no

change. Anyone have any ideas, this is really getting to be a problem.
