RE: VP530 Audio delays
I used 23.70.248.177 which was mentioned on the firmware page as it was a higher version number. This problem occurred with the previous firmware that I was using. I shall try the firmware that you mention to see if that makes a difference.

I have no other Yealink phones as I was trying this one out to see how it performed. All other phones are either Aastra (480i) or softphones.

Ok. I have factory reset the phone and installed the suggested firmware. Still the same. I am using the PCMA codec, which I presume is G711, a-law encoding.

Using the Asterisk echo test, if I count from one two five, I literally finish saying "one" before it echoes back the "one", same with two, three, four and five. If I use my soft phones or Aastra phone, there is virtually no delay, maybe 50ms or so - it almost echoes as I speak. I am using the G711 a-law codec with the Aastra phone and the soft phones.
