Hello everyone. i am a windows administrator but a 3cx and a voip noob. i wanted to get into it to understand more and i set myself up with a simple task. have someone call in from google voice and have it ring to an IVR and make calls from the 3cx through google voice. i thought i did my research and found people talking about using the obitalk 110 to make it happen. i saw tha the obi 202 was just released and that the obi 110 allowed 2 voip connections while the obi 202 allowed 4. I figured the obi 202 was better than the 110 and didnt realize their was a PSTN component that the 202 didnt have until i started running into problems in the setup. i setup 3cx version 10 with no problems. setup extensions and even setup cisco sip phones. i setup the obi 202 with google voice and registered it as an extension on the 3cx no problem. i can call the obi extension from the 3cx, i can call to a analog phone on the obi from google voice. But i could not call out using the obi202 from 3cx. i was able to call into the 3cx from the obi but then the way i got that to work meant that any call from the 3cx to the obi went to the ivr even the outgoing calls that plain didnt work before. I contacted obi support and this is what they said. Requirement: 1. your SP2 needs to have status of "Registered", so that OBi can make calls and be called. 2. Use a different username than 110, because the above X_InboundCallRoute defines what OBi does if there is an incoming call from 110 On your 3cx, disable register. You suppose to still be able to dial out if you don't register. so i quickly realized a few things. if i use a username like 456 the 3cx will register the obi. if i use a username like tom456 the 3cx will not register the obi as an extension. I also didnt know how to setup the obi as a sip provider with the 3cx without registering it. i would appreciate any direction or any help you gentle people can provide. Thank you.
