New subject: [Users] modifying From/To headers with uac module?

30 Nov 2006

Good to know!
Strangely enuff, I got the same response from a handful of people too :-)

FWIW, I'm probably still going to mess around with getting uac_replace_to operational,
'cos it does seem to be somewhat useful (especially with some of the stranger carrier
requirements that I'm starting to see out there)

cheers

as a former level3 engineer who wrote some of level3s voip platform
parts and current customer i can tell you with certainty that level3
only enforces the e.164 requirement on the from and to header during
interop.  if you can mock up your headers long enough to pass interop
and production turn up you can then safely terminate traffic to l3
without e.164 formating.  they will not refuse your calls once you
make it to production.

of course a better solution may be choosing a meta carrier like
bandwidth.com ( where i work )

hope this helps

  FWIW, i've been bemoaning the lack of 'To'
rewriting for a while myself.
 Level3, in its infinite wisdom, has decided that they need the RURI, From,
 and 'To' headers to be in a very specific format (prepended '+', 10
digits,
 etc., etc.)
 I can get the RURI and 'From' exactly the way they need it, but the 'To'
is
 definitely beyond my ability.

 Do let me/us know if you intend to go ahead with 'uac_replace_to'.  It would
 be trememdously useful...

 Thanks Bogdan.  I'll have to double-check with them;  They may have only
 meant they wanted the From in E.164 so that Caller ID works correctly.

  Hi Alan,

 my advice is to change the PSTN termination since their service is not
 RFC compliant - TO header has no use in routing, only the RURI being
 used (according to the RFC 3261 ~ 3 years old).

 but to answer to your question, yes that is the proper place and the
 mechanism is 95% the same as for FROM hdr.

 regards,
 bogdan

  Hello,

 I see that UAC allows modifying the From header, but I would also like
 to modify the To.  This is because an ITSP I will be testing with wants
 the From and To to be written in E.164 form (rewriting the R-URI appears
 not to be good enough) while my internal registrations use a 5-digit
 extension.  It looks like uac is the right module for this but it
 appears that it can only modify the From header with uac_replace_from()
 and uac_restore_from().  Would this be the right place to add
 uac_replace_to() and uac_resotre_to() as well?
