EX60 can´t make a Call to E20 SIP device

[Nelsonmejia09]

EX60 with SW TC4.1 is register in CUCM 8.6 like SIP third party SIP device and E20 is register in native mode in CUCM (SIP) but i can´t make any call from EX60 to E20. any idea to fix this issue?.

- can you make calls from the E20 to the EX60

- make sure in the EX60 the default call signaling/type is SIP

- is the SIP address using name/numer@CUCMIP address format

-  I have not maked calls from E20 to EX60 yet, becouse i don´t have remote acces to the E20 to do that, then I will do this test when I have local access to the devices.

- I have turned off H.323 service in EX60, then the defualt call singnaling is SIP.

- I have configured EX60 device with 2002@CUCMIP format. but the Ex60 and E20 have asigned 2002 and 2001 numbers in the CCUCM, like others ip phones. Do i need do some special configuration in the CUCM?.

- if you can access the E20 via ssh you can generate a call through the CLI

- can you dial the E20 by typing the full SIP URI like 2001@CUCMIP and see if dose work ?

- i am assuming basic CUCM config if correct in terms of Partitions and CSS
