[Serusers] SER Windows messenger on-line problem

[Kissandrakis S. George]

Hello,

I have installed SER 0.8.14 with radius-mysql authentication
besides the default routing, 

alias=ipv6.uoc.gr
.......
        if (uri==~"sip:ipv6.uoc.gr") {

i have

        if ( uri=~"sip:[0-9][0-9][0-9][0-9]") {
                forward (MY-GW-IP,5060);
		};

i have two accounts in radius kissand at ipv6.uoc.gr kissand2 at ipv6.uoc.gr
and with windows messenger 5.1 i go "online" and i can make calls with 4-digit 
numbers with both accounts

If i go "online" with kissand at ipv6.uoc.gr and kissand2 at ipv6.uoc.gr (registered normally)
from different computers, kissand at ipv6.uoc.gr sees offline kissand2 at ipv6.uoc.gr and
vise versa

with ngrep i get

debbuging SER i get

sipsak gives the same results


My sip server's ip is 147.52.3.244 resolves to edet.ucnet.uoc.gr
SRV record fir _sip._upd.ipv6.uoc.gr resolves to 5060 edet.ucnet.uoc.gr
Is it a problem that the server is not in ipv6.uoc.gr DNS domain?

If not any hints about "Too Many Hops" between users?

Thank you
