I have problems with too many branches for

stamp 41150. Other phones are working properly. X-Lites are trying to
subscribe each 40 seconds with different rinstance strings. Example:
Out of curiosity, what is rinstance parameter, and what is it used for?
The Internets doesn't seem to know.
It is a proprietary parameter to identify which registration caused an
incoming call.
E.g. a SIP client registers to 2 proxies, e.g. klaus(a)iptel.org and
klaus(a)fwd.pulver.com. It will use the contact header
sip:user@localipaddress.
If there is an incoming request, the RURI is sip:user@localipaddress and
the client can't reliable tell if this is an incoming call from
iptel.org or fwd.
By adding a different instance header for each proxy it is possible to
distinguish incoming calls, e.g.:
Contact: sip:user@localipaddress;rinstance=1234 for iptel account
Contact: sip:user@localipaddress;rinstance=5678 for fwd account
btw: snom phones use line=... and AVM Fritz use uniq=...
