tsearle created an issue (kamailio/kamailio#4505)
### Description
We've encountered one carrier that in the ACK and BYE would add a ;user=phone
to the RURI, appending it to the contact uri generated in the 200 OK of the
invite. This prevents the topos module from doing a successful lookup of the
tps param
This patch fixes the issue and brings the logic closer in line to topoh
### Troubleshooting
Adding debug statements, I found that when ;user=phone is added, the parameters
end up in sip_params instead of params. I've also noticed that topoh checks
both sip_params and params when doing a parameter lookup but topos only looks
as params
#### Reproduction
modify the stock sipp uac script as follows
ACK [next_url];user=phone SIP/2.0
BYE [next_url];user=phone SIP/2.0
