Intermittent Problems with Transfer calls and Parking

[tex834]

Hello,

We have had various types of intermittent problems with the phones since the initial install 2 months ago. The system is 3cx v11 with Yealink T38G phones. Below are some specific examples.

Problem 1: Occurred on 9/19, Attended transfer problem.... The employee answers the incoming call > presses the transfer button > dials the target extension > (then nothing happens) > So, then press the resume button to unhold the call > then press the transfer button to try again > (nothing happens).

Problem 2: Occurred on 9/17, Park problem... The employee answers the incoming call > press the programmed park 0 button > then presses the park 0 button again to resume call > (nothing happens) > after 5 tries, eventually able to resume the call. > Then after finish the call, the park light remains red without anyone parked there.

Problem 3: Sometimes a persons BLF light remains red for 10 or 20 minutes but they are not on the phone.

Thanks

Will likely need more info, but the first thing to check is the phone firmware. You might even consider doing a factory reset, installing the latest firmware, provisioning the phone and trying again. I have t38s all over and they are pretty solid; not having the same issues.

Agreed. No mention of what SP level (assuming SP4) and Yealink firmwares. Yealinks have been very solid for me as well.
