[SR-Users] How do I make subst_hf() use variables in search (not replacement)?

[Daniel-Constantin Mierla]

I haven't looked at the code, but probably the function doesn't accept 
variable for the matching regular expression.

If the IP/port of asterisk are not changed, you can try:

#!substdef "/ASTERISKIP/127.0.0.1/"
#!substdef "/ASTERISKPORT/5080/"

asterisk.bindip = "ASTERISKIP" ...
asterisk.bindport = ASTERISKPORT ...

subst_hf("Contact", "/ASTERISKIP:ASTERISKPORT/$td/", "a");

Cheers,
Daniel
