Caller Picture Display

  • The caller picture feature allows the snom m9 Handset to display the picture of the calling party
  • All photo pictures need to be in 40 × 50 Pixels JPEG format
  • Caller picture is displayed when the snom m9 has a VCARD with picture available for calling party in the Address book
  • Alternatively, picture of the caller can also be sent to the snom m9 Handset, if the calling-party provides a SIP "Call-Info" header in the incoming call

Picture from Address book

  • Open the picture file in a graphics tool such as GIMP for editing
  • Re-scale the picture to 40 × 50 Pixels
  • To store the picture, click on Save and then select Save as jpg
  • Note: Other settings in the Advanced Options can be left as default (If needed, the compression rate can be increased)
  • Once the picture has been stored, open the VCARD for your Contact in Microsoft Outlook, and assign the picture to the Contact
  • Upload the VCARD to the snom m9 as explained in Address Book section
  • Note:* If the calling-party has a VCARD without a picture stored on the snom m9, a default Avatar is displayed for that Contact

Picture from Calling-Party

  • A Calling-Party may also provide its picture as a link when making a call to the snom m9
  • Such links can be provided in the SIP Call-Info header of the incoming call INVITE as shown below:
 Call-Info: icon=""
  • On receiving such a SIP header, the snom m9 will download the picture file from the link and display it on the associated handset

Handset Volume Control

  • The Ear Protection setting activates lower speaker volumes on connected snom m9 Handsets
  • By default this setting is turned on. Turning off the setting re-enables the normal speaker levels on the connected Handsets


Intercom/Auto Answer (SIP)

  • Activating “Intercom Incoming” for a SIP Identity enables the associated snom m9 Handset to automatically accept all incoming calls
  • The snom m9 requires SIP Alert-Info functionality from the calling party, but does not require 'Intercom Incoming' activated to respond to SIP Alert-Info.
  • Enter starcode prefix in Intercom Starcode Prefix for outgoing intercom e.g. when the setting is *97, and the user dials *971234, the m9 will place an intercom call to 1234
  • Note: The m9 also supports Intercom via Call-Info: answer-after=0 parameter. For this to work the Server Type for the Identity has to be set to snom ONE


Calling and Called Party ID

  • By default the snom m9 handset is set to display only the Calling Party ID (CLIP)
  • This behavior can be altered through the setting Identity->Behavior->Show Called-Party-ID
  • With the Identity->Behavior->Show Called-Party-ID switched on, the handset is able to display both the Calling and Called Party number or name
  • The F and T labels stand for From (Calling Party) and To (Called Party) respectively
  • The Number Display Style setting allows users to display the Name or Number of the calling party as desired


  • The CLIP property sets the state of the calling line identification presentation service on the m9. If set to Show, the m9 presents its number to the called party. If set to Hide, the m9 places the call from an anonymous account
  • The CLIR property sets the state of the calling line identification restriction service on the m9. If set to Accept, the m9 accepts calls from anonymous users who do not present the calling-party number. If set to Reject, calls received from anonymous users are rejected.

Outgoing Line Selection

  • Allow Line Switching: When the setting is turned on, Handsets can call across SIP Identities (See Example Setup)
  • Dial Format: <Identity Index> * <Number>
    • Examples of Line Switching:
      • Dial 1*1234 -> Handset Dials 1234 from Identity 1
      • Dial 7*956 -> Handset Dials 956 from Identity 7
      • Dial 4567 -> Handset Dials from current Identity for the Handset

Address Book

Address Book

  • Every SIP Identity of the snom m9 is able to maintain its own Address Book
  • This allows snom m9 Handsets to have personalized Address Books
  • Contacts can be entered manually or uploaded in VCARD 3.0 (or below) format via the snom m9 Web Interface
  • VCARD (RFC 2426) is a file format standard for electronic business cards and is often attached to e-mail messages, but can be exchanged over the internet as well
  • Contacts in address book are used for performing Name lookups for incoming calls
  • Stored contacts of one Identity can also be exported to other SIP Identities

Exporting a Single VCARD

Step 1: Export Contacts from Outlook


Step 2: Copy & Save Contacts

Step 3: Upload VCARD(s)

Bulk VCARD Upload

  • VCARDs can also be uploaded as a bulk file separated by BEGIN:VCARD/END:VCARD tags.
  • Edit each stored VCARD with a text editor and copy the text into a single file as shown below:
FN:Forrest Gump
FN:Shrimp Man

  • Save the file as e.g. mycontact.vcf
  • Upload the file as in Step 3
