How to get rid of extra information in SIP URI?

Question

Asterisk

Good afternoon!
Asterisk 13.13-cert, PJSIP 2.5.5, realtime.
Faced with an unpleasant situation - some SIP-phones and softphones add some of their parameters to the URI. For example, a contact of one softphone looks like this: sip:[email protected]:6642;rinstance=4as2ad8ads7 and with each re-registration, the value of rinstance changes, which is why contacts related to one AOR begin to multiply. I need to have 2-3 contacts per AOR, so remove_existing does not help .
I tried to use the ignore_uri_user_options=yes parameter , but I did not find any changes - URIs with additional parameters still fall into the database.
Help advice.

Answer 1

You would specify exactly the phone models.
It's just softphones - it's easier to change to another program
For hardware phones, it usually changes through hidden parameters through provisioning
For yealink, there is an account.x.instance_id.enable parameter with a parameter of 1 or 0
that adjusts this parameter, but not for all models in the line
