[Spce-user] Problems with ROUTE Header in SIP-Messages from client

[Klaus Peter v. Friedeburg]

Hi there,

I have some problems with some kind of CPE (Zyxel). This device send a Route-Header in the all SIP-Messages pointing to our NGCP-Server
f.e.
"Route: <sip:blabla.my-domain.de:5060;lr>"
Where blabla.my-domain.de:5060 is our NGCP

The result is that no call are successfully.

Do you have any idea to eliminate this route-header?
