<div>Hello Andrew,<br>
<br>
if you manage your SIP registrations via xml_curl instead of a
static dialplan, you have the variable "sip_user_agent" (e.g.
sip_user_agent=Aastra%206739i/3.2.2.2044) available in the params,
and then you can restrict the registrations based on the content
in this variable.<br>
<br>
<br>
Best regards<br>

<br>
We already know that we can allow/deny a SIP end point to
get registered to<br>
FreeSWITCH on the basis of IP , but what about if we want it
to filter<br>
"User-Agent" field in REGISTER packets to be the key for
registration.<br>
<br>
Since , we can also use TLS based registration but some soft
phones does not<br>
have that capability. In that case , is there any way of
passing only<br>
specified USER AGENT SIP client?<br>
<br>
Thanks<br>
