No audio on Siemens IP Phone for outbound call using voipbuster
 

Problem Siemens IP Phone

Using voipbuster for outbound I can't hear the person that I call.

If I use voipbuster without Voxalot in between it does work perfectly. What can be wrong?

I also have a C450 IP phone and have been using VOIPBuster. Things havw worked great. I saw a post for VoXaLot and setup this as my VOIP on the C450 IP. Phone registers with VoXaLot, but cannot route calls via Voipbuster.

Can someone post the configuration setting to get it working.

Thanks!

Please note: All Betamax family VSP work fine when making outgoing calls but fails when someone calls you. I think there nay me multiple of problems and I find it surprising when everything (inbound and outbound) works fine on my GSM wifi phone.
When I say multiple of problems mean it could be ATA or the transalations of codecs between voxalot and voipbuster.
