<p class=MsoNormal><span lang=EN-US>We are experiencing problems connecting a
CUCM 7 with a Siemens PBX using 2 MGCP-Gateways with 1x E1 PRI each and QSIG
protocol configured. <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Calls from the CUCM to the Siemens PBX and
also to the PSTN through the Siemens work.<o:p></o:p></span></p>

<p class=MsoNormal><span lang=EN-US>The Siemens PBX also has other trunks using
DPNSS and calls to destinations on these DPNSS-trunks fail when using QSIG.
When the call gets disconnected the following message can be seen on the
gateway.<o:p></o:p></span></p>
