<div dir="ltr"><p dir="ltr">Hello guys,</p><p dir="ltr">I would like to talk and ask, what is the best way to do Extension Mobility in my case. I will try to explain the topology.<br></p><p>I have my CUCM cluster, and i have two phones, Extension Mobility is working fine login and logout with ms ad credentials, the phones are configured with a dn 1001 and 1002, both are on PT_LOGOUT and CSS_INT_EMER, when the users at this phones log in the will use the same numbers 1001 and 1002 but now they are on PT_LOGGED and CSS_PERMIT_ALL.</p>
<p>When somebody call from PSTN the CSS from gateway is configured first with PT_LOGGED and after that with PT_LOGOUT.<br></p><p>The user on PSTN hear busy tone, cause 1001 and 1002 on PT_LOGGED are created associated with EM_UDP, and this EM is not logged on phone.</p>
<p>I configured a CSS_FWD and associated this with DN on PT_LOGGED forward unregister this CSS_FWD has the PT_LOGOUT numbers. And take the DN option in blank, if i complete de DN option it works.</p><p>Somebdy has this same problem?<br>
</p><p dir="ltr">Thanks.,<br></p>
