Hi,
Nothing is jumping out to me here in the Invite, if this is working for other destinations but not this one then the SIP response might truly be the answer here: 607 - Unwanted - "
The user agent(UA) of the called party, based on input from the called party or
some UA-internal logic, uses this to indicate that this call is
   unwanted and that future attempts are likely to be similarly
   rejected
"
https://datatracker.ietf.org/doc/html/rfc8197

Doesn't seem to be a Kamailio issue if it is only affecting this destination and if it doesn't affect the service on the Kamailio itself.

Thanks,

John.

Hi Mustafa,

Ideally we would need the Invite to better understand this, the 607 is in response to the Invite. Whether this is something in the Invite itself or something at the called end we don't know.

Thanks,

John.

I'm wondering how to handle situations where downstream send invalid messages. In this case, Kamailio is not able to send DELETE commands to rtpengine due to parsing errors, as a result rtpengine is consuming all available ports and causing instability in our VoIP infrastructure. Do you have any suggestions on how to mitigate this issue?
