SPA3102 FXS port

Question

Hello,
I have a problem with my SPA3102's FXS port.
In last April I tested my friend's two PAP2T adapters with four phones. The adapters were connected to same switch with different fix IP addresses and phones were able to ring each other. Then I got one of adapters from him as a gift and on 2nd of January I bought an SPA3102 - so I have two adapters.
I connected my adapters to same switch. Their parameters are:
PAP2T IP: 192.168.0.221
  FXS #1:
    SIP port: 5060
    display name: 1
    user ID: 1
  FXS #2:
    SIP port: 5061
    display name: 2
    user ID: 2
SPA3102 IP: 192.168.0.222
  FXS:
    SIP port: 5062
    display name: 3
    user ID: 3
Dialplans:
PAP2T Line1:        (<2:>S0 <:[email protected]:5061>|<3:>S0 <:[email protected]:5062>|<[x*]:>S0 <:[email protected]:5060>)
PAP2T Line2:        (<1:>S0 <:[email protected]:5060>|<3:>S0 <:[email protected]:5062>|<[x*]:>S0 <:[email protected]:5061>)
SPA3102 FXS:      (<1:>S0 <:[email protected]:5060>|<2:>S0 <:[email protected]:5061>|<[x*]:>S0 <:[email protected]:5062>)
Well there is problem with third phone (SPA3102 FXS port). Phones with PAP2T work perfectly, they can call each other. The 3rd phone has dialtone sometimes only but it is unable to call the other two phones. "1" and "2" can call third phone sometimes but another time I get reorder tone when I dial "3".
I have made backups from adapters' settings. Does somebody have any idea about this problem?
Thanks in advance,,,

Hi,
Problem is solved... 
SPA3102 has two RJ45 outlets: LAN and WAN (internet). I have used LAN only because of switch and the INTERNET terminal was empty. It appears to me this situation drives SPA3102 crazy...    I had to make a "loopback" plug (I linked contact 1 to contact 3 and contact 2 to contact 6) and insert it into INTERNET outlet. So all of phones work well...
If you want to use a PAP2T lonely (without internet access) as a "micro-PBX" with two extensions, you will have to use same plug otherwise phones won't work.
