I found out a solution with the Cisco Phones. There is an Option
"Outbound Proxy" wich I didn't noticed before. It works if I set
"Outbound Proxy" to SERs IP Adress and "SIP Proxy" to the Domain.
But I have another problem with aliases. If I add some aliases (the same
ones as in ser-0.8.14), they don't work.
SER says "100@mydomain" not found in usrloc.
Here is a short part of my ser.cfg:
if (!lookup("aliases") && !lookup("location")) {
sl_send_reply("404", "Not Found");
break;
};
