[OpenSIPS-Devel] [opensips] When t_relay returns, the global variable route_type is not set back to REQUEST_ROUTE or FAILURE_ROUTE (#365)

[mikomarrache]

Hi,

```
route {
   if(!route(NEXT_HOP)) {
      ......
   }
   while(!t_relay("2")) {
      if(!route(NEXT_HOP)) {
         send_reply("500", "Error");
         exit;
      }
   }
}

route[NEXT_HOP] {
   ............
   t_on_branch("branch_changes");
   ............
}
```

As you can see, the route block NEXT_HOP computes the next hop and arms a branch route for processing specific to the selected next hop. When t_relay is called, the branch route is executed but may be dropped (using drop() ) if some condition is met. In case the branch is dropped, t_relay returns an error and the next hop is computed again. If no next hop is found, a reply is returned. However, I get the following errors when the reply is returned:

```
CRITICAL:tm:w_t_reply: unsupported route_type (8)
ERROR:signaling:sig_send_reply_mod: failed to send reply with tm module
```

t_reply can't be called from a branch route. I expected the global variable route_type to be set back to REQUEST_ROUTE but it is not the case.

Is it a bug?

Thanks,
Mickael
