[OpenSIPS-Users] b2b top-hiding problem with custom_headers

[Jeff Pyle]

Hi Ancu,

No more problems with the buffer size!  Excellent.

P-Asserted-Identity still doesn't make it through even though it's defined in the custom_headers list.  Everything else seems to.  Any thoughts?

I'm going to need more than 10 headers in the list.  But when I try, I see:
  ERROR:b2b_logic:mod_init: Too many extra headers defined. The maximum value is 10 .

Is this an easy adjustment in one of the files?  I'll need 20 to be safe.


- Jeff
