I have configured SIP trunk with authentication. the authentication is username and password. I use CUBE to acheive this.
the call flow is like the following
phone ---> CCM 6.1 -----> H323 ----> CUBE -----> Firewall -----> Internet ------> SIP provider.
while I do troubleshooting, I found a message told me that the firewall traversal is not enabled.
I do stun configuration by using the following commands
voice sevice voip
stun flowdata agent-id 10
voice class stun-usage 1
stun usage firewall-traversal flowdata
after that, the firewall traversal message disappear from the logs. but the call is not working.
the sip provider has a STUN server, how we can use it ? and also what is the STUN ?
thanks in advance
Do you have captures from CUBE for a failed call?
It shows me a dead call, when I do.debug ccsip calls.regardsAnasSent from Cisco Technical Support Android App
That reply is not helpful,
capture debug ccsip messages
And provide the logs.

Seems like the SIP Server does'n like the FROM header:
You can modify the FROM header with a SIP Profile:
voice class sip-profiles 1111
request ANY sip-header From modify "sip:(.*)@" "sip:[whatever they want to receive]@"
You may ask your Service Provider what they don't like on the INVITE, then you can modify it accordingly.
Some information if STUN:
