My DID provider telasip supports E911 call. What I need to do is to pass callerid to them. I have something like below and for some reason it does not work. Please advice what is wrong? Thanks in advance.
If I do not want to hardcode the callerid in Set function, how can I pass the callerid dynamically? I have a vairiable callerid set in my agi script. every time a call is made, callerid is set. How do I pass this to set function?
