Re: [OpenSIPStack] INVITE and multi via:

[<sa...@ER...>]

Hi eric

Yes, UA->OSBC->SIPX->OSBC->ITSP.  We are determine to use OSBC with sipX.
At this point it seems very dueable but it's the choice of ITSP that will be
the stumbling block.  OSBC needs an admin screen to minipulate the INVITE to
tailor them to various ITSP requirements.

Good Luck with your guide
