I have a different problem, it parks the call but not on the Preferred Park Orbits we specified in the Account??

[Yealink Phones Audio Problems]

I have read some past comments about audio problems with the Yealink phones. We have a site complaining of one way audio and fading in and out during calls and i wondered if anyone has any more experience with this. The handsets have G729a and G711a as their preferred Codec's (in that order) and the Account for each phone is set up the same way (G729a first then G711a). Likewise with the codecs on the SIP Trunks which also have "Lock Codec During Call" set to "NO".

 

The Yealinks have the latest June 2010 firmware on them.

 

Appreciate any advice on this as it is an urgent problem.

[one way audio for the first 8 seconds]

before we could reproduce the problem "in vitro" (it only happens randomly to us) we found out a hack that seems to have solved the problem in the sense that no user is complaining any more:

 

on the yealink phone navigate to phone -> voice -> JITTER BUFFER

set "Type" to "Fixed"

set all 3 delays to 120 (Min Delay,Max Delay,Normal Delay)

done

 

CAUTION: I don't understand the logic behind this hack and I haven't researched it. The only good thing is that I have a few phones with these settings for many days/weeks and nobody has complained.

 

Can you tell me if the one way audio problem and fading in and out during the call is still fixed by this change. I have a client with the same problems and we have both G729 and G711a enabled. Was about to change all handsets as the client is NOT happy?
