Hi K,
Glare occurs when two endpoints, party a and party b, send a re-invite to each other at about the same time. So, from the perspective of party a, it has just sent a re-invite to party b and instead of receiving a 1xx or other response message it gets a re-invite, causing it to not know how to proceed. As an example, both parties might invite each other, simultaneously to a conference center. Or another example, both endpoints, involved in a voice call, might invite each other to a video call. This is described in RFC 3261 under re-invite, including what the endpoints should do.

Hi Forum,
Can anyone tell about the glare in SIP. How does it get created ? What is the scenario in this case.
