[SR-Users] via header not removed wit hremove_hf()

[Richard Robson]

hi ,

Thanks Hennig,


I added the counts to check and i'll retest with the ms_+appl_changes() too.

The real problem is that the Via is getting into the relayed INVITE. I 
had assumed that it would not get relayed if it were removed.


Regards,


Richard
