According to this SO question I tried to forward received message to multiple destinations with the following Lua script. But in the second UA I got duplicate Via header. Here is the Lua script:

```Lua

KSR.forward_uri("sip:ali@192.168.1.50:7080;transport=UDP");

KSR.forward_uri("sip:tes@192.168.1.50:9080;transport=UDP");

```

And here is the received Via headers is `tes` UA:

```

Via: SIP/2.0/UDP 192.168.1.21;branch=z9hG4bKbe8c.953ed42f0bcc438c6991121d3483010b.0
Via: SIP/2.0/UDP 192.168.1.21;branch=z9hG4bKbe8c.953ed42f0bcc438c6991121d3483010b.0
Via: SIP/2.0/UDP 10.189.219.4:5060;rport=5060;rport=5060;branch=z9hG4bK-4177-1-2

```

Would you please help me to forward message to multiple destination without duplicate Via headers?
