SX20 does not connect expressway e via internet

[ackarabas]

Hi everyone,

I have a problem with registration between expressway e and sx20 telepresence. We moved our sx20 to different network. We want that sx20 register to expressway e via internet. However, I received registration error from expressway e as unknown domain.

If you want to get some inf. from me about expressway E, I did all mra conf. on expressway E and now all company use vpnless jabber without problem.

Any thoughts?

Regards

[ackarabas]

yes I get same results when I want to register. Do you recommend which I configured wrongly URI of SX20?

hi,

I encountered such problem like you too. I have Jabber for Windows and for Android succesfully connecting through internet but not SX20.

I tried use this document - http://www.cisco.com/c/dam/en/us/td/docs/telepresence/endpoint/codec-c-series/tc7/administration-guide/administering-endpoints-running-tc72-on-ucm1051.pdf for configuring SX20 but it didn't work, you can look at p. 48. I can't see any log events after I've configured by this document. when I try configure SIP username in username@domain.com format I can see following error in the log:

have you get the same events in the log?
