Hi, looks to me, like a typical DNS error. How did you configure DNS? You have BIND up and running and a proper Zone-File? Do the CSCF's properly query the DNS?

Hi, the Zone-File is the interesting part, not the Bind-Config. Did you configure the outbound Proxy on Zoiper properly?

You can actually see in the trace, that the Proxy-CSCF is forwarding the packet to itself (looping) and at some point it drops the request.

Hi Mihail, you could also see the REGISTER in the PCAP, if you did not configure your DNS/BIND properly... Thanks, Carsten P.S.: I regularly test Zoiper with our own setup, it works... and it even should work with the 4.4 version, you're running. 2016-05-30 17:25 GMT+03:00 Mihail Dakov <mihail.dakov(a)ng4t.com>om>: > > On 05/30/2016 04:11 PM, Carsten Bock wrote: >> Hi, >> >> the Zone-File is the interesting part, not the Bind-Config. >> >> Did you configure the outbound Proxy on Zoiper properly? > Yes, otherwise the REGISTER from the UE would be missing from the pcap, > right? >> You can actually see in the trace, that the Proxy-CSCF is forwarding >> the packet to itself (looping) and at some point it drops the request. >> > I see that as well.
