[asterisk-dev] chan_sip and early media

[Valter Nogueira]

I am originating call using early media option.

Whe I issue a hangup (like in hangup request sip/...) before the b-leg
answer, it don't send a SIP CANCEL and the call keeps going on.

I figured out that it is happening due to sip_hangup() checks:

* if (p->invitestate < INV_COMPLETED && ast_channel_state(p->owner) !=
AST_STATE_UP) {*

* needcancel = TRUE;*
* ast_debug(4, "Hanging up channel in state %s (not UP)\n",
ast_state2str(ast_channel_state(ast)));*
* }*

And *ast_channel_state(p->owner) == AST_STATE_UP*

I guess that early media option puts channel state in AST_STATE_UP

So, is there a way to not set up channel state to *AST_STATE_UP* in early
media? Or the state check could be removed?

Thank you,

Valter
