Using chan_mobile - no audio both directions

Hi,

I configured my Android phone as a mobile trunk using chan_mobile.
Aterisk is running on a Pi3 and has version number :

Both incoming and outgoing calls on this mobile trunk are being handled and they both get connected. However, there is no audio to both parties.

I set debug level 1 on Asterisk.

I get :

[2018-01-18 01:36:10] DEBUG[8288][C-00000002]: audiohook.c:272 audiohook_read_frame_both: Read factory 0x6de69efc and write factory 0x6de6a91c both fail to provide 160 samples

while ringing.

and I get :

[2018-01-18 01:36:20] DEBUG[8288][C-00000002]: audiohook.c:333 audiohook_read_frame_both: Failed to get 160 samples from write factory 0x6de6a91c

when the phone is answered.

how can I troubleshoot this problem ?

thanks

I’d appreciate a response from somebody who knows chan_mobile or has experience…

Alas, it’s lightly used, and most of the parties that hang around these parts have no experience with it - as evidenced by the lack of response. Good luck.
