Hello,

do you want to add q value to Contact header on incoming REGISTER requests?

Cheers,
Daniel

I have a need to use q-value for serial forking but my clients don't support it. I need to specify unique q-value on all ports on the client device.

I explored using the User-Agent header and appending q-value, but this wouldn't help on multi-port clients.

Some things I have been thinking about are 'abusing' the authorization user or from user to somehow append q-value but this opens the door to other issues, and a database trigger however there would be no way to match this up to a record in another table as the usernames would be the same.

Any thoughts/ideas or methods others have used in situations like this?
