Anyone else have problems with phones like SPA-922, SPA-921, etc?
Inbound audio is perfect but the remote end reports audio quality
issues on the audio the handset is sending out. It's not the
network.... I've tried asterisk 1.2, 1.4. I've used ulaw, G726, G793 &
G729. Ulaw seems to be the least problematic but its still an issue.
Doesn't matter if we send the calls to the PSTN via IAX or SIP or PRI.
I don't know it if happens all the time but about 40% of the time the
remote caller reports they cannot hear me.

Yep it was set to 0.030.. but the odd thing is the issue is random and
also whenever I call my mobile phones to test it seems to work fine on
the old setting.

We also use the Linksys SPA IP phones for our clients. We always change this setting to "0.020", which vastly improves audio performance.

What are peoples thoughts on changing it to something lower, e.g. 0.010?
Thanks,

Daniel Cole

Can you describe the issue more please? Can the remote person not hear you at all? Or is there distorted/broken voice?
Cheers,

Daniel Cole

The issues i have been having are probably similar to the original
message, I use the Linksys 9XX Series phones and we used to always
receive complaints from the person we were calling that they could
hardly hear us.

I fixed this by:

Going into the Phone section of the config and setting the Handset,
Speakerphone and Headset input gain to 6.

And i also went into SIP and changed the RTP Packet Size to 0.020

This resolved the low volume issue, Sorry if you have a no sound issue,
but thats how i resolved very low volume.

Phones sound great now!

Regards,
Kevin Sandalin

I have found with a number of clients to who we have installed the LinkSys phones, that when you get the input gains to 6, that the phones have a tendency to pick up too much background noise. Have you experienced this at all?

Cheers,

Daniel Cole

No, I haven't experienced this.

I think were lucky because most voip phones are in there own offices, I
will check with our sales manager this afternoon who sits in the call
center and see what the background noise is like on her phone.

I guess i'm just lucky that its a quiet environment, But there are a few
people who *may* be affected and i will check this out and let you know.

Kevin

Ok, no worries

Most of our clients have a relatively open common work area, where the phones are located. I would be interested to know what your sales manager has experienced.
Cheers,

Daniel Cole

Distorted and broken noise at the remote end. The odd thing is I can
never reproduce the issue but it very constant. I have set the 0.020
setting and I will continue to test with G723.
