Hi,

I need to check if an AVP is blank, how can I do it?

This is what I have in my script:

        avp_write("tU","$avp(tmp)");


I need to check if the content of this tmp AVP is blank, how to check this??

What I need is to check if the TO Username from SIP URI is blank if so, I
need to push the To URI into the To URI Username.

Thanks,

Fernando
