T23G no audio outbound calls

[ropiecin]

Model: T23G
Firmware Version 44.80.0.95
Hardware Version 44.0.0.16.0.0.0
Server: Asterisk

We have to buy some new phones for our company so we have bought a Yealink T23G model to test this brand, unfortunatelly we immediately have an issue: inbound calls work fine but there is no audio on outbound calls to outside lines!

Any feedback would be greatly appreciated

Hi,

Which Router do you use? it might be a firewall causing one way audio

[ropiecin]

no firewall active!
notice that other phones of other brands are working without problem, only Yealink T23G have this issue!

[ropiecin]

it should be an issue with G729 codec, cause if we disable it then audio of outboung calls is working fine.
Hope you fix this bug soon.

BR,
Piero Bud
