[asterisk-users] Addition: Problems with one-way audio in ACR Phone
Also a addition:
If I call from the 8961 TO the ACR phone client audio works fine both
ways.
Its only when I receive a call from the DID where audio becomes one-way on
the ACR Phone client but nowhere else.
And notice that no asterisk sip.conf settings were changed before switching
from native Android to ACR Phone.

Ämne: Problems with one-way audio in ACR Phone
Here is my problems (sent a copy to the developer of ACR Phone aswell):
I have a mobile phone with ACR Phone client, and a fixed Cisco 8961
connected to a PBX with DID.
Incoming calls answered in the 8961 audio works both ways fine
Outgoing calls called from the 8961 audio works both ways fine
Incoming calls answered in the ACR Phone client I can only hear the
calling person, the calling person cannot hear me.
Outgoing calls called from the ACR Phone client audio works both ways fine
Im using a VPN tunnel to the PBX server, so there no problems firewall-wise.
The SIP on the phone worked perfectly when I ran Androids native SIP, but
since native SIP support was dropped in android 12, I switched to ACR phone
as SIP client, and since then the audio problems on incoming calls started.
Here is a incoming call where audio doesnt work (calling party doesnt hear
me). Calling party CAN hear the IVR however, so I didnt include the IVR,
but only the parts from when sip09 (ACR phone) rings.

Huh? Child handler, but nobody there?
== MixMonitor close filestream (mixed)
== End MixMonitor Recording SIP/cellip-0000000d
Any ideas what could be wrong?
Note that I have NAT on for the client in question, because the client in
question changes IP. For example, when in wifi reachability, it will not
connect through VPN but directly via wifi (on the same network as PBX).
