[SR-Users] Substitution of Contact Header

[Mack Hendricks]

Hey Daniel,

I hope all is well!

I tried to make it super simple

The regular expression is this:

subst_hf("Contact", "/@.*>/@107.21.184.251>/", "a”);

The Contact looks like this

Contact: <sip:3135421245 at 10.0.0.140:53349;alias=98.209.240.245~53349~1>

It ends up like this (it concatenates it)

Contact: <sip:3135421245 at 10.0.0.140:53349;alias=98.209.240.245~53349~1 at 107.21.184.251>

I really want this

Contact: <sip:3135421245 at 107.21.184.251>

I do call Nathelper functions in some cases.  I can comment those out.  What am I missing?
