<TITLE>Zultys Zip 2 Registration / Disabling SIP Authorization</TITLE>
</HEAD>
<BODY>
<P><FONT SIZE=2>I'm trying to get a Zultys Zip 2 phone working with Asterisk. The phone seems to be failing registration (see sip debug output below). However, I can place calls TO the Zip2 from other SIP phones (Grandstream BT-101, Xten X-Lite, and eStara Softphone) and from Nortel PBX extensions coming in to Asterisk over a PRI T1. The problem is that I cannot dial any extensions from the Zip 2. Any extension gets an immediate busy signal and NO output from sip debug (not even any packets in tcpdump). The Zip 2 does show up in "sip show peers":</FONT></P>

</P>
<P><FONT SIZE=2>Zultys support (which has been pretty good so far, by the way) says that the Zip 2 does not yet support authorization, and that I need to "disable authorization" on Asterisk. They say they have tested with Asterisk, and Asterisk is listed on the compatibility list for the Zip 2. </FONT></P>
<P><FONT SIZE=2>My sip.conf for that phone follows, along with the relevant output from sip debug when the phone tries to register (Asterisk is on 10.1.1.45, the Zip 2 is 172.16.0.163). How do I disable authorization for this phone, beyond not specifying a secret? </FONT></P>
<P><FONT SIZE=2>Is anyone successfully using Zultys phones with Asterisk? What am I missing?</FONT>
