Linksys spa2102 (SIP problem - hold/unhold)

Hello,

I am owner of Linksys spa2102 (VOIP Adapter), and I have a next problem with SIP function on this device:

In every case of incoming calls (only incoming) I and my companion cannot hear each other, but if I press Hold than Unhold it - 

everything start warking, and we can already hear each  other.

 

Please, help me if you know any detail of this problem, which could help me for setting up my device. 

 

Thank you

So many possible causes. NAT, firewall, misconfiguration issue ...

 

Please capture the SIP packets of a call. It should disclose more.
