cannot receive incoming calls
We are using "deutsche telefon" as sip service provider. The configuration uses the udp port 5060. Outgoing calls work fine but when receiving a call from external we can see in the log that there is something happening but the application does not come up with an incoming call. The log also does not show any errors. Incoming calls using any other application like microsip work fine. Also outgoing calls to for example my mobile for works fine. I also tried version 3 but it seems to have the same issue. I have tried all available settings but couldnt figure out what is the cause. Any help will be appreciated.
