Hello, I have just finished to install SER for the first time and I followed the instructions from the document How To SER. But I have some doubts: -->I put on the variabel SIP_DOMAIN the host name of my computer which is in the DNS server. Is this correct or should I put the IP address of my proxy machine? -->In the ser.cfg file I change the "mydomain.com" to the host name of my machine. Is it Ok? -->I have my MySql database running, with the ser database created and with a defualt admin user. But I coudn't register my SIP phone in my proxy. The phone gives this error: " Proxy registration failed. Disabling proxy. Reason: registration denied (SIP/2.0 483 Too Many Hops)" Note: I have already uncommented the database lines in ser.cfg like was said in the instrations. Any help with be very apreciated. Thank you.
