Callpickup without audio

[Ero]

Hi team ,

When make direct call between IP phones the audio works well but when the IP phones use the feature callpickup *20* the audio doesn't works

The version 3CXs is: 18.update 9 built 20
IP phones: Yealink 30P(firm 124.86.0.75) and Yealink 43U (fim 108.86.0.70)

The 3CX and the IP phone are in the same network

The funcion callpickup works well with weclient and Apps



Best regards

Hi team . The issue was resolved , the problem was that in the Fortigate was activated the SIP ALG feature.

Thanks
