I tried to connect Cisco IP Phone SPA525G2 to OBi202 following the instructions from "Configuring an OBi Voice Service Bridge to connect a legacy IP Phone".
"ITSP Profile D and SP4 on the OBi202 shall be configured as a proxy for the IP phone.
• ITSP Profile D/General/SignalingProtocol = SIP (default)
• ITSP Profile D/SIP/ProxyServer = 192.168.1.10 (ie IP address of our SPA962 IP Phone)
• ITSP Profile D/SIP/ProxyServerPort = 5063 (SIP listening port for our IP Phone)
• ITSP Profile D/SIP/X_SpoofCallerID = yes (or checked, this will ensure we pass the caller ID through)
Next, create the local voice service that the IP phone will use as its proxy:
• SP4/X_ServProvProfile = D (We're saying use the ITSP D profile with this voice service)
• SP4/X_UserAgentPort = 5063 (Note: you can choose a port that you prefer, just be sure to use the
same port number throughout the tutorial
• SP4/X_RingProfile = B
Configure the IP phone to register to the OBi and use it as it's proxy
On the IP phone, set-up the following parameters:
• SP4/X_RegisterEnable = no (or unchecked)
• SP4/AuthUserName = 1001 (This can be defined by you, but needs to be the same on the IP Phone)
• SP4/AuthPassword = AnyPhonePassword (Once again, you can define this, but must be the same on
the IP Phone)
• SP4/X_Proxy = yes (or checked)
• EXT 1/Proxy = 192.168.1.20:5063 (ie: IP address of OBi202)
• EXT 1/User ID = 1001
• EXT 1/Password = AnyPhonePassword
• EXT 1/Register Expires = 60
• EXT 1/Register = yes
• SIP/Send Resp To Src Port = yes"
I used OBi Expert on
OBiTALK.com to modify the config for my OBi202. Somehow, the field SP4/AuthPassword kept being overwritten by the system to "Device Default". When the IP phone tries to register, it fails since the password will not match. I got "Registration State: Failed - Authenticate" on the IP phone info page. Now the Cisco phone can only answer calls but not dial out.
Does any one have similar issue and know how to solve this puzzle?
Thanks a lot in advance!
