[Asterisk-Users] Sipura SPA-841 Volume Oscillation Problem

Hi all,

 

The problem is on the volume of the voice sent by the SPA-841. I think the
echo cancel algorithm sets a limit to the microphone when detects sounds or
noise from the earphone. This problem generates an oscillation on the voice
volume sent by the phone and even turns it off completely for very little
lapses of time making the communication very uncomfortable. I manage three
different implementations with Asterisk and Sipura SPA-841 on different
clients and network topologies, and on every one we are experiencing the
same situation.

 

Thanks,

jergas

[Asterisk-Users] Sipura SPA-841 Volume Oscillation Problem

Greetings,

I'm experiencing the same problem. It manifests itself mostly in noisy 
environments - as soon as there is some increase of the ambient noise 
the volume in the headpiece or the "speakerphone" decreases
immediately,
and starts to randomly increase/decrease for some time after the ambient 
noise gets low. This is 100% repeatable if you start the conversation by 
using speakerphone. As soon as you switch to the handset, the defect 
disappears. Now the problem is that 5% of calls via headset have the 
same problem.

I am using the latest firmware for the SPA-841.

[Asterisk-Users] RE: Sipura SPA-841 Volume Oscillation Problem

The firmware sipura are currently offering is pretty awful.
We bought 60 of these and our supplier in the UK was able to document  
and diagnose the problem. Sipura were then able to produce an updated  
firmware that made them sound almost like normal phones again. There  
is still a slight echo but the volume fluctuation and the echo during  
doubletalk is now gone. the version is 03-01-03-a-0623j.
You should be able to request it from sipura directly. If you can't,  
let me know and i'll have a word with my suppliers here.

[Asterisk-Users] RE: Sipura SPA-841 Volume Oscillation Problem

Greetings,

We installed a number of SPA-841 in a office environment, originally
firmware was 0.9 something and the audio in the headsets worked really
well, with virtually no muting of received audio.

When I first upgraded a couple of the phones to 3.1.2 the headset audio
went to crap, muting incoming audio with any sort of background noise in
the room. Speaker phone is totally useless (any sort of room
noise-including incoming audio mutes the speaker) so I disconnected the
internal microphone and just use the speakerphone mode as a monitor for
off hook dialing.

Recently upgraded to the new release of 3.1.3 didn't make the headset
audio any better (but also didn't seem to make it any worse as some
people on the list seem to have observed) 

We where using the couple of units with 0.9 something for the
telephonists with headsets, but the phones crashed a number of times & I
had to update to the latest firmware now their headsets are pretty much
un-usable.

I was going to make up an adapter to hook the headset through the
handset port as handset audio doesn't seem to go through the same muting
problems, but this sort of defeats the purpose of having a simple phone,
with speaker (monitor) mode, handset and headset modes built in.

Suspect if the put in an option to turn off the audio muting for the
headset it would fix our problem, but we are probably going to have to
bite the bullet and put a couple of Cisco 7960 in for the headset
wearers.
