I have set up DIDlogic as my first sip provider long time ago and it worked just fine. Recently I decided to try to register with one more service provider - Zadarma (from Bulgaria telecom). I did everything, to my surprise Sp2 registration failed, in addition, on the status page IP address of the server for SP2 is the same as for SP1 (belongs to DIDlogic). I tried factory reset, and played around for quite a while but still cannot understand why SP2 tries to register with DIDlogic, not with Zadarma.
I did set up Zadarma in my Android SIP app and it works just fine.
Pls see screens of my configuration in attach.
Thank you in advance.
