Hi Jean,

May I know how do you configure CUCM and Asterisk to achive that?

I have encountered a problem when try to integarte CUCM 8.5 with Asterisk using SIP trunk.

CUCM -> Asterisk (not working)

Asterisk -> CUCM (error 399: Unable to find a device handler for the request received on port 5060)

For your info, I have changed the "outgoing transport type" to UDP.

Thank you.

Alex

Not sure whether you've sorted this yet Alex, but make sure the device pool on your SIP trunk contains a Call Manager group with the CUCM server acting as the SIP end point ( configured in Asterix )  and is the primary server in the CUCM group.

Regards.
