  • Nick Barnes, Thu 08 of May, 2008 [13:44 UTC]: Christopher - I can't see any way in which an Asterisk installation would muck your GUI, but remember that it is advised not to use a GUI on an Asterisk box anyway.

SIP method invite re-invite

From the SIP RFC:

...This modification can involve changing addresses or ports, adding a media stream, deleting a media stream, and so on. This is accomplished by sending a new INVITE request within the same dialog that established the session. An INVITE request sent within an existing dialog is known as a re-INVITE.

Note that a single re-INVITE can modify the dialog and the parameters of the session at the same time.



re-INVITE caused a lot of trouble if we don't know exactly what's going on with UAC/UAS at the time re-INVITE happen.

re-INVITE for Multimedia Conferencing

by Arif-Uz-Zaman on Thursday 18 of May, 2006 [03:28:07 UTC]
What is the exact re-INVITE for Multimedia Conferencing?

Scenario like this:

UA1------->UA2 (on Hold)
UA1------->UA3 (on Hold)
UA1------->UA4

Here, UA1 is caller. UA2, and UA3 are on HOLD.

Help me with your valuable feedback.

Thanks in advance.

Re: Invite (hold)

What are you trying to ask? Are you asking how a SIP UA should initiate a HOLD to another SIP UA? If that's the case then it is done with a RE-INVITE. The RE-INVITE will have an SDP that specifies the connection ("c=") should be to 0.0.0.0 (e.g. "c=IN IP4 0.0.0.0").

See ya...
