我在32位ubuntu服务器中配置了带rtpproxy的opensips服务器。 我的配置文件在下面给出
#
# $Id$
#
# OpenSIPS residential configuration script
# by OpenSIPS Solutions <team@opensips-solutions.com>
#
# This script was generated via "make menuconfig", from
# the "Residential" scenario.
# You can enable / disable more features / functionalities by
# re-generating the scenario with different options.#

使用此配置文件，我可以连接我的软电话，我也可以拨打电话。但是当呼叫启动时，它会打印下面的日志。我做错了什么？

您似乎在没有SDP正文的请求中调用了 engage_rtp_proxy（）或 rtpproxy_offer（）。
为了防止这种情况，您应该在rtpproxy代码中使用以下条件：
if (has_body("application/sdp")) {
... rtpproxy stuff ...
}
