Delay between call pickup (queue) and voice channel

[jjwerkman]

Does someone have experience with this issue?
Everything works fine. A caller is connected to a queue. The queue will search a agent. The agent pickups the phone and starts with his greetings (ie. Goodmorning, you are speaking with...). The beginning of his greetings (Goodmorning) is not received by the other end. The callers heares: you are speaking with...)
We use the Yealink SIP-T38G and the SIP-T28P.

Hi jjwerkman,

the issue that you are facing may be caused from a lot of issues and needs to be investigated through wireshark as it may have Jitter or any other factor that affects the call.
As a first step check the Firmwares of the phones. If you are on Version 12 SP6 the correct firmware for the T38 is 38.70.0.221 and for the T28 2.71.0.225. If on Version 11 check to have the correct firmwares through the Management Console.
Keep in mind that the default templates need to be used.
