Hello,

In my lab I am testing a SIP VoIP SDK Server App and a SIP VoIP SDK agent App. The environment is as  follows

In my laptop (192.168.0.112) I have all I need for my testing:

- The Voip PBX (Mizu)
- The SDK Server App (registers to the Mizu with ext 2801)
- The SDK Agent App (registers to the Mizu with ext 2714)
- The customer, who is Zoiper (registers to the Mizu with ext 1111)
The test:
1. Customer (Zoiper ext 1111) calls to ext 2801 in SDK Server. The call is answered OK
2. My VoiP SDK Server analyzes the call, and decides to transfer it to an agent (SDK agent ext 2714)   with a redirect ...  The redirect fails with SIP 408 (Timeout)

I can not attach the Mizu logs. However, I uploaded to Drive .. this is the link

Pls see the only call to 2801 and from then on.
Appreciate your kind help
Thanks and best regards
