Disable SIP options ping reply on CUBE

[Sinisa Hreljac]

Hi,

is it possible and how to disable replying to SIP Ping option sent from ITSP but allowing other SIP messages?

Situation is that our ITSP is using SIP ping to detect link availability, so if there is no response on SIP ping they redirect new calls to secondary link. However, we sometimes have needs to clear our primary link of calls, so only solution that we see is that we stop responding to SIP options so ITSP would redirect new calls to secondary link. We will then wait for allready established calls to finish (because that we need to allow oher SIP messages) and our gateway will be free of calls. Is this possible with CUBE (ISR4331)?

Not that I’m aware of. SIP option ping is a regular SIP message, with a specific content, so there is no way to achieve what you ask about.

Per this post you should be able to to achieve what you ask about by simply turning off the inbound dial peer used for your service provider inbound calls. This would not in any way affect ongoing calls.
