Update to 1.2.9.1 which addresses a security vulnerability in the IAX2
channel driver (chan_iax2). The vulnerability affects all users with
IAX2 clients that might be compromised or used by a malicious user, and
can lead to denial of service attacks and random Asterisk server crashes
via a relatively trivial exploit.

Siproxd is a proxy/masquerading daemon for the SIP protocol. It
handles registrations of SIP clients on a private IP network and
performs rewriting of the SIP message bodies to make SIP connections
work via an masquerading firewall (NAT). It allows SIP software
clients (like kphone, linphone) or SIP hardware clients (Voice over
IP phones which are SIP-compatible, such as those from Cisco,
Grandstream or Snom) to work behind an IP masquerading firewall or
NAT router.

oSIP provides a SIP stack with a limited set of features common to
any kind of SIP Agents. Thus oSIP is not oriented towards any
particular implementations and can be used for implementing SIP
End-Point, Proxy or any kind of more specific SIP Agent such as
B2BUA.
