Joshua Colp commented on ASTERISK-18703:
----------------------------------------

Per the Asterisk versions page [1], the maintenance (bug fix) support for the Asterisk branch you are using has ended. For continued maintenance support please move to a supported branch of Asterisk. After testing with a supported branch, if you find this problem has not been resolved, please open a new issue against the latest version of that Asterisk branch.

Thanks!

> I tried a few days to send a message with the help of the i= field in the SDP part of an SIP packet during a call setup from a Caller to a Callee.
> According to RFC 4566 the i= field can be used for:
> "The "i=" field is intended to provide a free-form human-readable description of the session or the purpose of a media stream.  It is not suitable for parsing by automata."
> However the Asterisk server does not accept the INVITE packet when the i= field is set. The same call without the i= field does work properly. Furthermore in the debug/verbose output (set verbose/debug 4 and sip debug to on according to the bug tracking rules in concern to SIP) does not show me any information about the acceptance of the packet with the i= field. It is just ignored/not accepted. This prevents to setup a call.
> I took a look to the source code and found that in the file: chan_sip.c no i= handling is present. (May be its something else).
> The correct behaviour is: The i= flag and the following text (e.g. i=This is a company call) is set by a Caller and send to a Callee. It must not changed in the asterisk it just has to be forwarded in the SDP file to the Callee.
> However using the same call with my local sip provider (sipgate) the packet is accepted and forwarded to the Callee.
