SIP Uniform Resource Identifier (URI) based dialing One of the 9 newest feature for CUCM version 9
This is beyond anything you imagine Finally we will forget about calling each other by extension number and the we will start typing the email ID instead to make a call. Seriously SIP URI can be best compared to an email address such as Aysar.Mohamed@ccieroot.com or Aysar.Mohamed@mynaghi.com.sa . A users can dial the called party via URI if they are using 8961, 9951 or 9971.
make sure you have to upgrade the IP Phone firemware to 9.3.1
A SIP address or SIP URI is a Uniform Resource Identifier written in firstname.lastname@example.org format (semantically, much like an e-mail address). It addresses a specific telephone extension. A SIP URI can be automatically imported from LDAP (provided the cluster is integrated with an LDAP server such as a mail or the msRTCSIP-primaryuseraddress attribute.
The user name is case sensitive however host is case insensitive (RFC 3261). This parameter is configurable starting CUCM 9.1 (under Enterprise Parameters – URI lookup policy)
Now Configure a phone and Add Dn as you normally Do then go back to the end user and associate the Device and select the primary DN which you want to bind the Directory URI to it
Its automatically bind to the DN
*The Directory URI is put into an automatically generated partition called “Directory URI”. If you wanna call other DN with Directory URI configured, make sure your CSS has the partition Directory URI.*
You can try to make a call now. It only supports on hook dialing for URI dialing, so you press the new call softkey, the press the “A B C” softkey so that you can enter alphanumeric characters.
If you don’t want to call the full directory URI, you want to call without the domain name, make sure you change the following in the Enterprise parameter.
and yes it’s Calling by dialing the email address email@example.com not the extension
