[asterisk-users] SPA3102 registration problem

[Jaap Winius]

Hi list,

After failing to get a Sipura/Linksys SPA3000, which I've configured  
as a PSTN gateway, to pass on the Caller ID, I decided to try my luck  
with a Linksys SPA3102 after hearing some promising stories.  
Unfortunately, I've run into a completely new problem: it seems  
Asterisk won't let this device register.

I went about configuring the SPA3102 in much the same way as I did the  
SPA3000 and the Linksys PAP2T. For example, in all three cases this is  
the way I configured /etc/asterisk/sip.conf for Line 1:

    [4000]
    type=friend
    host=dynamic
    context=phones-m
    secret=1234
    dtmfmode=rfc2833
    disallow=all
    allow=ulaw
    qualify=yes

The device is configured to register Line 1 with the SIP proxy and as  
a result the command "sip show peers" would eventually say the  
following:

    Name/username  Host           Dyn  Nat  ACL  Port    Status
    4000/4000      192.168.1.3     D             5060    OK   (13 ms)

Not so with the SPA3102, in which case I always get:

    Name/username  Host           Dyn  Nat  ACL  Port    Status
    4000           (Unspecified)   D             0       UNKNOWN

After some tests, I found out that the SPA3102 is indeed trying to  
register, but that Asterisk seems to be ignoring it. Using tcpdump, I  
can see that registration packets are regularly being sent to the  
Asterisk server (bitis):

15:30:49.567288 IP spa3102.umrk.to.sip > bitis.umrk.to.sip: SIP, length: 482
Eh........%........
.......xREGISTER sip:192.168.1.10 SIP/2.0
Via: SIP/2.0/UDP 12
15:30:49.568390 IP spa3102.umrk.to.sip-tls > bitis.umrk.to.sip: SIP,  
length: 492
Eh........%x.......
.......%REGISTER sip:192.168.1.10 SIP/2.0
Via: SIP/2.0/UDP 12

This sequence keeps on repeating. Also, if I change the sip.conf  
settings above to "type=peer" and "host=192.168.1.3", I'll see these  
messages appear on the Asterisk console:

[Feb 27 15:17:34] NOTICE[10893]: chan_sip.c:12414  
handle_response_peerpoke: Peer '4000' is now Reachable. (7ms / 2000ms)
[Feb 27 15:17:35] ERROR[10893]: chan_sip.c:8513 register_verify: Peer  
'4000' is trying to register, but not configured as host=dynamic
[Feb 27 15:17:35] NOTICE[10893]: chan_sip.c:14943  
handle_request_register: Registration from 'Margriet  
<sip:8000 at 192.168.1.10>' failed for '192.168.1.3' - Peer is not  
supposed to register

If, in this case, I configure the SPA3102 not to register any of its  
extensions, Asterisk will report them to be reachable and there won't  
be any more errors on the console, but in actual fact the extensions  
won't be available: I won't be able to call the phone attached to it  
due to congestion, and if I pick up that phone to make a call, I'll  
immediately hear a busy signal.

What could be causing this situation? I'm using Asterisk 1.4.14 and  
the SPA3102 has the latest firmware version: 5.1.7(GW). I should also  
mention that I'm not interested in using this device's broadband  
router functionality.

Any help would be much appreciated!

Thanks,

Jaap
