Avaya Equinox Quality of service on Android phone

[ejvl]

Hi,
We've a working solution with Avaya Equinox within CM/SM environment, release 7.
We use Samsung phones with WIFI and VoIP dialing, it works fine.
There is a problem with some Point Mobile phones. When there is an incoming call (VoIP) and this phone answer the call, the volume in the first 10 seconds is very soft, we can hear the caller hardly. About 10 seconds later, this problem is over and we can hear each other very well. This problem is only on this Point Mobile phones, not on Samsung, Sony, Apple, and so on.

We contact the manufacturer and they told us:

In sniffer, there is no QOS data frame, only QOS null data frame, this is normally BE ac,
if it is keep alive frame, this can be VO AC.
For voip app, it should be VO AC, this is decided by socket data priroity , app will set this,
wlan driver only map to VO ac, so you can capture a sniffer with QOS data frame to have a check.

Also, as you can see below, Spectralink device set 0(BE) instead of 6(Voice)
So I think the SIP Client has the option for priority.

Is this a setting in Android, or in the settings file of Equinox, or something else?

In the Avaya documentation I can only find QOS and prioritize settings on the Equinox server and they are well configured but I can nothing find about this settings for the app of in Android.

In advance thanks!

You say point mobile phones and the other guy says Spectralink

You say you hear the voice fine, but low for 10 s

QOS prioritize settings only apply to Avaya phones. Other device types will set QOS however they are configured to do so.

Check your SIP sig group in CM for your SIP phones for direct IP early media and look at a trace of them calling one another - see if the SDP in the first offer is between their IPs directly or through a media gateway first. Perhaps if its going through a media gateway first, and re-negotiates to direct audio within a second or 2, I could see your LAN QOS policies maybe having G450-->WAN apply tagging from the LAN core, but G450-->WLAN on prem not get QOS at L2/L3 because its not necessary and WMM on the WLAN deals with that.

So, based on the packet you posted, do the desired tags change after a few seconds?

Maybe it has nothing to do with the tags but maybe the spectralink tuning to the volume of the call from a gateway DSP that happens to be a bit different than when its direct to another endpoint and you'd just want to set the audio up directly between the endpoints the first time.
