<p class="MsoNormal">Is there an easy way to change the ip addresses in the SIP headers (both inbound and outbound) so that my CUCM and provider will both accept calls?<o:p></o:p></p>

<p class="MsoNormal">Example:<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">I have a 10.x.x.x/24 address on gig0/0, a PER address for BGP on gig0/1 and lo0 has the provider's desired signalling address..<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"> <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">CUCM isn't currently able to route to the provider signalling address as it is a 32.x.x.x address.
<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"> <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Would it be easier to have the network team set up routing to the 32.x.x.x address or could I change the headers to accomplish this?<o:p></o:p></p>
