I'm using EtherReal on the OpenPhone side (client),
and on the gateway side I'm loging with Syslog.
When the comunication is established, and from openphone side we don't hear audio, the Syslog does not register any errors.
Below Is an RTP incoming packet in the openphone side, originating from the gateway, but not udible.
