There is always a difference in how different vendors implement the spec.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Add ANI2 / OLI parsing for SIP. The patch checks the "From" header during the handle_request_invite() function for the presence of "isup-oli", "ss7-oli", or "oli" tags. If present, the up-to-2-digits following the equal sign in the tag are set on the channel's caller structure in the "ani2" int element.
This allows SIP functions that reference ANI2 to work properly for SIP. Specifically tested was the messaging that occurs when AGI transmits its data to an AGI script.</pre>

During the payphone call, the value of "agi_callingani2" was properly transmitted as "7" for the payphone, "62" for the cell phone, and "0" for the landline.
Over 600,000 calls have been processed in 12 hours or more of testing without errors.</pre>
