How do I setup my Grandstream Phone for SIPphone.com service?
Typical configuration is: SIP Server: proxy01.sipphone.com Outbound proxy: (leave it blank) User ID: xxxxxx (your SIPphone.com account number) Authentication/Login ID: xxxxx (same as above, your SIPphone.com account number) Password: xxxxx (your SIPphone.com password) NAT Traversal: Yes (You need to set up your STUN server if you don’t have outbound proxy) STUN Server: stun01.sipphone.com
