Call Parking - Yealink Phone - Asterisk 11 vs 13

[Velocita Technology]

Hi There,

Freepbx 10.13.66-22
Asterisk 11.25.3
Parking 13.0.19.7
Parking Pro 13.0.30.11
Yealink T29G Phone Firmware46.82.0.30 ( or 46.81.0.110 or 46.81.0.70)

Have programmable DSS key set to CallPark and 70 … works great, parks in 71 and announcement says 71.

Exact same scenario except Asterisk 13.18.3

Have programmable DSS key set to CallPark and 70 … works great, parks in 71 but you can hear the announcement start to say “Sev”… and gets cut off. the BLF I have set on a different key to monitor 71 lights up red.

Any ideas on what I can do to allow the slot announcement to finish before it completes the transfer and hangs up???
