Calls take time to make or are not made at all.

Hi,

We are having issues on our company with the calls, calls take time to make or are not made at all.

I'm seeing this logs on our router 2821.

Please elaborate what your mean by calls take time, is this for inbound or outbound calls? Does the call eventually go through?

What is your system: CUCM, CME something else?  

Provide full config of your GW (show run) and (show diag).

Is for outbound calls, for example when I make a call it take time to go through, but eventually it does.

Is CUCM, and the Voice Gateway is the Router where I saw those logs.

Provide full config of your GW (show run) and (show diag).

I've attached the output of those commands.

Sounds like you may be running into inter-digit timeout issues on CUCM.  What are the route patterns you are matching define as, do they end with "!", ie. 9.!? If so you need to make them more explicit so that CUCM does not wait till inter-digit timeout (T302) expires before extending the call. What does Dialed Number Analyzer (DNA) show?

Hi!

I can check that, my doubt is that, everything has been working fine for
years, no changes was made on the configuration but suddenly the issues
started happening.

Those logs about the service engine are normal?
