Exchange UM Breaks after some time

Recommended Posts

Hi there,

 

I'm facing an issue where my Exchange UM feature doesn't work after some time....

Should I call the auto attendent via pbxnsip it would not be resolvable..... or call could not be reached...

 

However, once I re-start the pbxnsip, everything starts working again.....hopefully someone can help :)

 

the following are the logs i have collected:

Smells like a DNS problem to me... Maybe you can use the IP address in the outbound proxy instead to see if that is the problem. Keep the DNS name in the domain, so that Exchange does not complain.

Hi IPNOX, :(

 

please try to troubleshoot this at ExchangeUM first, if this is reproduce-able behavior. Please activate UM Diaglostic Logging at Expert Level: http://technet.microsoft.com/en-us/library/bb430783.aspx I prefer the PowerShell steps.

Then wait until the problem comes back. In the event-viewer you might be able to see the cause for the issue in nearly clear text. Please report this errors or warning to me.

 

btw: Please tell me more about you deployment! You should not e.g. run pbxnsip and ExUM on the same machine, or combined with any other SIP-Solutions.

 

sorry for this delayed response, but I can only check the forum every once in a while.

 

regards,

 

Jan :)
