<div>The OPTIONS Ping will come across in the regular SIP stack (TCP:5060/TCP:5061 or UDP:5060 typically). Prioritization is a Quality of Service technique and not an Access Control technique. I don't think a standard ACL would look at the application layer
header to differentiate SIP messages and offer priority of individual SIP messages. </div>

<div>Hi Saranyan, </div>
<div>thanks! I would like to know how can I compose an access-list to detect SIP option ping and prioritize it.

<div>OPTIONS ping is a SIP message. Ideally the transport mode of the message is TCP or UDP based on the configuration done under voice service voip -> sip.</div>
<div>Otherwise, we can configure a keepalive profile so that we can specify the mode of transport for the OPTIONS keepalive messages. </div>

<div>Hi Group, </div>
<div>I would like to find out if SIP option ping is a "ping" or a "sip message" ?</div>
<div><br>
</div>
<div>From the documents, it seems like it is a sip messages. </div>
<div><br>
</div>
<div>My customer is facing issue with the dial-peers getting busy out during WAN congestion. We would like to prioritize those messages as a WAN provider but they are not able to give us the exact commands for the CE router.
</div>
<div><br>
</div>
<div> Currently this is the command on all their managed "voice gateway" </div>
<div> * voice-class sip options-keepalive up-interval 120 down-interval 120 retry 2</div>
<div><br>
</div>
<div>This means the "transport" mode is default. This make things more complex, I have no idea it is TCP or UDP or ???</div>
<div><br>
</div>
<div>With no access to customer network (unable to do wireshark), I would like to see if there's anyone having the experience to prioritize those SIP option ping packets?
