asterisk users - Feb 2008 - MWI problem with Siemens Gigaset S675 IP

Hi list,

Before purchasing a number of Siemens DECT SIP phones, the Gigaset  
S675 IP, I read that the problems with MWI had been fixed with the  
latest firmware version (see  
http://www.voip-info.org/wiki/view/Siemens+Gigaset+S675IP). Now I'm  
not so sure that's the case.

After setting up a network mailbox for one of these phones, as well as  
an Asterisk voicemail account (ext. 1000) in voicemail.conf's default  
context, I added the following line to my phone's context in sip.conf:

   mailbox=1000

However, soon after executing a 'sip reload' on the console, the  
following error message will appear every three minutes:

   [Feb 13 19:18:22] WARNING[14171]: chan_sip.c:12621 handle_response:
    Remote host can't match request NOTIFY to call
   '1742fb0c598dc6ec444a5ea64a2103ae at 192.168.10.10'. Giving up.

The IP address belongs to my server. At the same time, I used tcpdump  
to see what else might be going on. I found the following:

   19:18:22.540113 IP bitis.umrk.to.sip > gigaset.umrk.to.sip: SIP, length:
545
   E..=.... at ......
   .........)..NOTIFY sip:1000 at 192.168.10.5:5060 SIP/2.0
   Via: SIP/2.0
   19:18:22.571452 IP gigaset.umrk.to.sip > bitis.umrk.to.sip: SIP, length:
308
   E..P.......f.......
   .....<a_SIP/2.0 481 Call Leg/Transaction Does Not Exist
   Via:

The latest comment on the voip-info.org page above outlines the same  
problem. Can anyone here confirm that this is indeed a Siemens  
problem, or might it be an Asterisk problem after all?

I'm running Asterisk v1.4.14 on a Debian etch server.

Thanks,

Jaap

Try adding mailbox=1000 at default  (or what ever your voicemail contexxt is)

I've had to add the voicemail context to get MWI to work correctly in the 
past.

The "481 Call Leg/Transaction Does Not Exist" response to the
NOTIFY makes me think that you might need to configure the
phone to SUBSCRIBE to MWI - do you see any SUBSCRIBE messages
from the phone when it is booted?
