UC520 SIP trunk unable to make outgoing calls, incoming calls are ok

I have an new SIP trunk set on an UC520 and the incoming calls are ok, but the outgoing calls are getting an busy tone(not working).

The bellow trace is showing that the cause is "No route to destination (3) ". The question is this route has to do with the firewall(ip routing) or with the voice translation rules?

bind media source-interface "VOIP_INTERFACE"

Beginner

For the moment I only have

Thanks I will give it a go

Beginner

Please debug calldebug ccsip

Please debug call

debug ccsip calls

May be it is because of wrong dial-peers

Also some providers ask to send Caller-ID as Outside number ( I mean that calling outside You should configure your City number as outgoing)

Beginner

Hi Emil,Bellow is the debug

Hi Emil,

The provider is providing full number caller id, the outgoing number is in form of 0111111111. The user to make an call is dialing 9 then 0222222222 the external number

Bellow is the debug calls and sh run

UC_520#debug ccsip calls

Hi Emil,

 

I've removed both, but no change.

Almost all the config is made through CCA.

The issue was resolved in

The issue was resolved in part on the provider's side.

On UC520 side by adding an outbound rule to fa0/0, to allow traffic to SIP IP. And adding an static route to allow 0.0.0.0/0.0.0.0 IP default gateway.

Hi Emil, I've added bind

Hi Emil,

 

I've added bind control and media interface but outgoing calls are the same blocked, strange thing is that the cause is still no route to destination (3)
