Call forwarding: no audio

Hi there,

I have a freepbx running in a Rpi3, with this configuration:

Land line via SPA3102
GSM USB dongle
Hotvoip SIP account

When answering calls locally, everything works correctly. However, call forwarding has this issue:

When a call is received on the GSM dongle, it is forwarded to the hotvoip account, but there’s no audio in both parties.

If a call is received on the landline, forwarding to hotvoip is done correctly.

Locally, there’s always audio.

Here is the log, of the transfer when the audio fails:

(the log is too big to fit in this post)

Anyone can help me on this?
