[reSIProcate] How to send a re-INVITE

[郑卿]

I used the same way scott mentioned. For example, I used the
re-Invite method to realize onhold
function.

with my code fragment:
----------------------------------------------------------------------------------------------------------------------------
 // here pis is InviteSession*
 SdpContents* pSDP = dynamic_cast<SdpContents*>(pis->getLocalSdp().clone());
 assert(pSDP);
 pSDP->session().connection().setAddress(Data("0.0.0.0"));
 pis->provideOffer(*pSDP, DialogUsageManager::None, 0);
 delete pSDP;
---------------------------------------------------------------------------------------------------------------------------

Caval
