Android phone and mobile network issue.

[James E]

Hi there,

Myself and my work colleagues have Android phones running software version 12 and the latest version of Vodia app.

When we are  connected to our mobile network(Telstra in Australia) and pickup or make calls the phone connection is silent, we can't hear the person on the line and they are unable to hear us.

Any help would be fantastic as without wifi our phone system useless when on the road.

Hello James E, 

Can you please check the firewall settings (where the PBX is installed). Please check if the ports are enabled as described in the manual:

Also, for media related problems it help to enable PCAP traces and then look at the packet log (see https://doc.vodia.com/docs/pcap).

check PCMA/PCMU setting.  We found mobile inbound was sending PCMU and the Vodia set to PCMA and no audio - removing PCMU from the Vodia worked but is not a solution...

The problem is that according to the RFC it is totally fine that the codecs for the different directions are not the same. You can try an internal call, and if it fine this might be a trunk problem. Many SIP trunks have problems with different codecs on send and receive. On the trunk side there is a setting "Number of codecs in SDP answer" — set it to 1 so that it is always clear what codec to use. Or force it to a specific codec, e.g. PCMU.

We noticed the same problem in France the vodia application on iOS works well but it does not work on Android. We use PCMA AND PCMU.

Tested on 68.0.14, 68.0.16 and 68.0.18

... also related to that problem we recently found an issue with OPUS which will be fixed in the next version. Those who want to try can use 68.0.19.beta.
