EX60 delays from 10 to 30 sec when calling another device

[jssalgado]

This Terminal EX60 Works OK, but the only thing is that when calling another device takes too long for the other device to receive the call.  This EX60 is registered to CUCM 10.5.1 and its firmware is tc7.2.0

ANY HINT?

Thanks so much for any help.

Are you dialing URI or extensions? If its extension, do you see some delay when dialing from a SIP phone on CUCM? You "might" be experiencing some post dial-delay. Try assiging an extension a URI and call this URI directly and see if you have a delay.

There are a few IP Phones and all of them  Works just fine (no delays).  We are dialing extensions only.
