Sip trunk between cucm with cucm and cucm with asterisk

I have a trunk between cucm 6.1.5 and asterisk but when a call is made from cucm to asterisk it disconnects immediately it is picked (call from asterisk to cucm is ok). But it is working with cucm 10.5. I try route call from cucm 6.1.5 to 10.5 then cucm 10.5 to asterisk, but could not make a call from 6.1.5 to asterisk. Message log on cucm 10.5 said "404 not found". Any idea?

For the call disconnect at call answer that would indicate a codec negotiation issue. Look at what codecs you advertise to the receiving end and also what it responds with.

Apart from that CM 6 is well beyond everything, as is CM 10. Your strongly advised to use something more current.

If Im correct, for the inbound call to function with Asterisk, some form of routing is required on the trunk. The 404 error is likely due to this.

Furthermore, both versions 6.X and 10.5 have reached their end of life (EOL). Version 6.X reached EOL quite some time ago. It is strongly recommended to upgrade them to the latest version.
