[OpenSIPS-Users] Help trace source of error: unknown URI param list excedeed

[Muhammad Shahzad]

When reporting issues please make sure to add opensips version you are
using including operating system details. This helps in diagnosing problem
better.

Anyways here are the answers for your question,

1. This error means an invalid SIP packet is received which opensips was
unable to parse.
2. Yes you can inspect the packet in detail and do appropriate actions,
have a look at below URL to learn more

3. Yes, these could be symptom of possible DOS / DDOS attack OR may be some
valid user / trunk has really buggy device which creating bad SIP packets.
Take appropriate measures.

Thank you.
