Hi, We use sipxecs 4.0.4 and it is not behind NAT. Nat Traversal feature for remote workers is enabled.
I have some questions related with outbound proxy and registration refresh time (registration expiration time). Questions related to outbound proxy. 1. How do i test that my server is working properly as an outbound proxy server? 2. What will happen if i leave empty Outbound proxy setting on the phone? How the phone will work in this situation? 3. If Outbound proxy is left empty, then is it possible this to cause disconnecting the phone just after every call? 4. If Outbound proxy is left empty, then is it possible this to cause late registration refresh problem (phone disconects after a call and reregister after some time again, but later than Refresh time)? Questions related to registration refresh time (registration expiration time). 5. Which value is good to be set as Refresh time on the phone? I know that default hardcoded minimum time is 300. Does it make sence to put a lower value or a high value? 6. Which values can prevent late registration refresh problem? Lower values or higher values? All these questions are related to following problem with one of our hard phones behind NAT: When it receives a call, then it is disconnected from server, but in server side i see it still registered. It looks to me like a late refresh time problem. But i'm not sure of this.. This problem appeared when we had set the refresh time to 300s and outbound proxy was not set (left empty). We have set on this phone 180 seconds for registration refresh, outbound proxy to be sipxecs ip address. It is working right now and it seems like it does not disconnect now after a call a received. Can this refresh time be a problem at some point? _______________________________________________ sipx-users mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-users Unsubscribe: http://list.sipfoundry.org/mailman/listinfo/sipx-users sipXecs IP PBX -- http://www.sipfoundry.org/
