RE: Call forwarding with SIP devices Yealink and Cisco Call Manager CUCM
Hello Kevin,
You are right, everything works very well, despite the call forwarding and also the Music on Hold (but we can survive without the last for a while!) Wink
By the way, Cisco Call Manager can handle Third party phones as well with their own phones. Features like Transfer, Hold, Conference, Auto Redial, LDAP works like a charm!
Recently we approve Yealink T19 E2 Phones as the alternative to the Cisco basic Phones. In our environment we have something like 3.000 IP phones and other 4.000 conventional TDM, that we are planing to migrate in the next years with the new projects.
Attached are the two cenarios, the first with a normal call (Ext. 7235 call to Ext. 5065) and the other with the Call Forward feature activated (Ext. 6321 call to Ext. 7235 forwarded to Ext. 5065). As we can see, the Yealink handle well with the transfer, but when activate the Call Forward, the Cisco Call Manager answer is "Call cannot be completed as dialed", like the number does not exist (we tried with all possible combination, but with no sucess!). About the Cisco syslog, pacp we can provide as soon as we build the lab.

Thanks in advance,
