Hi everybody !
I try to set up a busy treatment on GVP instead of the "classic" busy treatment on a PABX.
To do so, I use a routing strategy who will forward the call from a customer (on PABX side) to the SIP Server switch.
If the agent is ready to take the call, the second routing strategy (on SIP Server side) will forward the call to the agent, but here is my issue : the client phone rings indefinitely but the agent phone doesn't ring

I don't understand the "Invalid destination DN" error message in the URS & SIP Server logs (I'm a newbie in Genesys).
If someone have an idea about my issue, please just let me know

This is the TROUTE of the routing strategy from SIP Server to PABX T-Server : TRoute['230003','SwitchA4400_01',RouteTypeDefault,'']
230003 is the agent I try to call (he's ready and he exists

)
SwitchA4400_01 is the name of the T-Server on PABX side.
This is the SIP Server log EventError :
