Re: [SR-Users] using forward() with variables

Thanks for your swift reply, Daniel. I would also like to thank you again for the great training last week. My main question was: Why does forward() not take dynamic parameters? Should it not do so (in the future) to be in line with other functions? It was not difficult to work around, but I think it would be more logical if the function could use dynamic parameters like all the other functions I've used can do.

I'm trying to use the forward() function with a variable like this: forward($shv(voip1-edge1)); That fails to parse. I then tried this, which I thought would fail: forward("$shv(voip1-edge1)"); That parsed correctly, but it then failed to resolve the domain '$shv(voip1-edge1)' as expected. Why can this function not use variables? I tried to make a workaround by doing this: $du=$ru; $dd=$shv(voip1-edge1); forward(); That also failed. Why is $du writable but $dd is not? I then made a fourth attempt, which seems to work: $du="sip:" + $shv(voip1-edge1); forward(); indeed, the last version is the one that works. forward() does not take dynamic parameters, only static string values. $dd is not writable because is just part of $du which you can set like you did. $du refers to outbound proxy address (destination uri) and there matters only host, port and transport, all the other attributes in $du have no relevance.
