[Serusers] RTP Proxy and SER

[Stephen Miles]

THanks for that Andrei, all sorted.

One last thing, getting a call from the PSTN to go to a soft phone 
registered with ser. I have tried a few route clauses like if 
method==invite lookup location etc but it doesn't seem to be working. Is 
there a simple thing I am missing here?

Thanks
Stephen
