[asterisk-users] E65 fails registration, soft phone works

Sat Sep 12 03:08:21 CDT 2009

Hey folks,

I am trying to get an E65 to connect to asterisk, and I would really
appreciate a second set of eyes. The SIP dialog completes fine, but
the phone subsequently says "Registration failed".

I am in a network that has what seems to be a SIP-capable NAT
gateway, but the asterisk is configured nat=yes anyway. Using
a softphone (twinkle), I can connect just fine, SIP and RTP work.

But when the E65 tries to connect, it seems to complete the SIP
REGISTER dialog, but then it'll say "Registration failed":

  (using tshark, full log at end):
  0.000000 86.197.113.72 -> 77.109.139.86 SIP Request: REGISTER sip:sip.madduck.net
  0.000398 77.109.139.86 -> 86.197.113.72 SIP Status: 401 Unauthorized    (0 bindings)
  0.234836 86.197.113.72 -> 77.109.139.86 SIP Request: REGISTER sip:sip.madduck.net
  0.250054 77.109.139.86 -> 86.197.113.72 SIP Request: OPTIONS sip:e65 at 86.197.113.72
  0.250134 77.109.139.86 -> 86.197.113.72 SIP Status: 200 OK    (1 bindings)
  0.424722 86.197.113.72 -> 77.109.139.86 SIP Status: 200 OK

asterisk will even see the peer:

  [Sep 12 09:56:32] NOTICE[18226]: chan_sip.c:17581 handle_response_peerpoke: Peer 'e65' is now Reachable. (174ms / 2000ms)

but then subsequent OPTIONS packets don't reach the client and soon,
the peer will be marked unreachable.

As said before, SIP works out of this network though!

I searched the web and found instances of this problem, but none of
the solutions worked (changing realm, using or not using proxy
server, …).

Here are the SIP details. Asterisk's realm is 'madduck.net'. As you
can see, the dialog seems just fine. But there must be something
wrong somewhere.

Maybe you can spot where I am making an error?
