Incompatiblity

  • There is no documentation about the provisioning. From my reverse engineering it looks to accept the same configuration file as the new incoming Polycom IP200W
  • The MWI VoiceMail messages does not seems compatible with Asterisk 1.4, there is no way the phone shows how many messages you've received.
UPDATE: MWI works with Asterisk 1.4.17. dkaufman
UPDATE: MWI is still not working fully - numbers of messages not displayed. bcnit
UPDATE: MWI works with Firmware 2.02 on an Asterisk 1.4.10, for number of new and total messages. OliverCH
  • The M3 does not use the same SIP stack as other SNOM phones (3xx), so be aware of a whole new set of bugs.
  • The handset doesn't support GSM, so if you want a low bandwidth codec, you'll have to run with iLBC or G.729.
  • The base station/handset(s) don't support provisioning in the same way as other Snom equipment.

Problems

  • gmaoret - With Elastix 0.9.2 (I don't know with other distributions) when a call is made to a busy or unavailable extension the base station reboots, losing all calls.
    • wmundy - Be sure you're using their latest firmware.
      • gmaoret - I'd tried all the firmware version available. No one works.
  • There is no way to download/backup/upload address book(s).
  • Log doesn't show enough SIP information to be useful (reason for failed registration etc.)
  • Log doesn't show DECT registrations. This makes adding other handsets difficult
  • Log can't be reset and timestamps are numeric (unix timestamps?) rather than the more useful real world times (date/time)
  • Firmware update takes forever and a day
  • There is no way to disable the 'Missed calls' message.
  • The handsets cannot be configured from the base station web interface (e.g. setting ring tones, PINs etc.) and have to be done manually
  • 1.07 - Miscellaneous freezes/hangs
  • 1.11 - When the IP address is set to 'Static', the home page of the base unit shows it's IP address as '0.0.0.0'.
  • 1.11 to 1.16 - MAJOR - Various reboots, lockups and resets causing disruption. The base unit has to be power-cycled to resolve these issues as it doesn't sort things out for itself.

Resolved problems (A.K.A. make sure you're using the latest firmware!)

  • No easy way to see which UAs are registered and which aren't (other than trawling through the log (see above))
  • There's a very big security hole (firmwares 1.01 and 1.07) : browsing http://snom_m3_base_IP_address/reboot.html will reboot the base immediately, even if you aren't logged in !! NOTE - tested with 1.07 and this is not the case. Even if it were, it would only be an opportunity for a DoS, not a security issue.
  • 1.07 - Just because a codec isn't on the list of acceptable codecs for a handset, it may still be used (fixed in 1.11)
  • Weird delay issues with audio travelling from the handset (going to the handset seems to be absolutely OK) when NATted
  • Address book is set up manually on each handset.
  • No keypad lock (available in 2.x)

Handset Codes

  • Keypad Lock: * + <right softkey>
  • Silence: # + <right softkey>

Configuration Tricks

  • Automatically log on to the VM (Asterisk 1.4+, firmware 2.x) without entering mailbox number and PIN (if you don't mind having the PIN visible on the handset and web interface)
    • Web Interface / Identity / Account Mailbox Name: Any name you like
    • Web Interface / Identity / Account Mailbox Number: <VMNumber>P<MailboxNumber>#P<PIN>#
    • Asterisk sip.conf: mailbox=<MailboxNumber>
    • <VMNumber> is the number you dial to access the VoiceMailMain, <MailboxNumber> is the number of the mailbox you like to listen to and <PIN> is the PIN of that mailbox.
