Refer works with cisco media GWs. Dunno about others. Re-INVITE with Replaces also works. They don't both work on the same code train yet;) Two different bug fixes not yet integrated into a single code release.
alan,
do you know if there is anywhere a document that lists what headers cisco ios gw acts upon? it is really scary if such a list does not exist. if i remember correctly, cisco used to accept cc-diversion header as charging number header. perhaps they still do and may be there are others that are as dangerous.
Maybe we need a remove_hf_except() function to strip all not explicitly allowed headers:
remove_hf_except("From|To|Via|Record-Route|Contact|PAI|CSeq|???????")
or something similar in result.
