problem with Obi200 and sip phone
mec755:
Hi,
I have a strange problem right now:
I started some days ago with a Obi110, configured it for GV and used the second account to connect with my Grandstream GXP2000. It was very easy and worked fine. I could receive and make calls from the SIP phone using GV.
However, I used the Obi110 only temporary and have now the Obi200. With this one I tried to do exactly the same - using sp1 with GV and sp2 to connect with the SIP phone. I think I did exactly the same changes which I did for the OBI110, gave the OBI200 the same IP the Obi110 used before, but it doesn't work.
Using a analog phone on the phone line, I can receive and make calls using sp1 - so the GV configuration should be fine. When I get an incoming call, the sip phone rings but when I take the call nothing happens except that the sip phone stops to ring and other phones still ring. If I don't answer the call on any other phone then the SIP phone shows after a while 1 more missed call. If I try to make an outgoing call from the sip phone I only get an error 404, number not found.
Here's the configuration with the changes I made compared to default:
IP 192.168.1.138
ITSP Profile B General
Name GXP
ITSP Profile B SIP
ProxyServer 192.168.1.103
ProxyServerPort 5062
RegistrarServerPort 5062
OutboundProxy 192.168.1.103
OutboundProxyPort 5062
X_SpoofCallerID checked
SP1 Service
X_InboundCallRoute {sp2(GXP),ph}
SP2 Service
X_ServProvProfile B
X_InboundCallRoute GXP>(xx.):sp1
X_RegisterEnable unchecked
X_KeepAliveServerPort 5062
X_UserAgentPort 5062
X_Proxy checked
AuthUserName GXP
GXP2000 configuration for line2:
IP 192.168.1.103
Port 5062
SIP Server 192.168.1.138:5062
Outbound Proxy 192.168.1.138:5062
SIP ID GXP
SIP Register No
As I mentioned, it worked perfectly with the Obi110, but I can't get it to work with the Obi200. Seems there are much more settings in there than for the Obi110. Anyone has an idea what could be wrong here?
ianobi:
I would try using a different port for the OBi200 sp2 and the GXP2000. Try something like:
SP2 Service
X_UserAgentPort 5091
GXP2000 configuration for line2:
SIP Server 192.168.1.138:5091
Outbound Proxy 192.168.1.138:5091
The default port for the your old OBi110 sp2 would have been 5061. Any port is ok so long as you use it consistently.

Still not working.
I switched syslog on and see the following for it (phone number changed to xxxxx, it also still says obi110.dyndns.org but it's the obi200):

edit: This syslog entries are received when I tried to make a call from the GXP2000
ianobi:
Try unchecking this:
SP2 Service
X_Proxy checked
X_Proxy is used when you wish to get the ip phone to register with the OBi200. Here you really are just looking for a simple ip to ip connection with no registration.
mec755:
Problem solved: I added a password under line2 on the GXP to connect to the Obi and also in SP2 in the SIP Credentials in the OBI200 configuration. Now everything works - incoming and outgoing is fine.
Edit: Ianobi, I only saw your post after I already tried with a password which worked. I tried now to remove the password again and uncheck X_Proxy, but then it's again not working. Seems there has to be a password in there.
