Hello,
someone tried such SNOM phone with Kerio operator?

When the contact is in the address book of the SNOM phone, name does not appear on the phone screen.
The name appears with a cisco phone and also on a softphone


Thanks for your help

Hi,

I don't think snom phones are capable of looking up numbers in the address book.

Best,
Filip

^^Can anybody confirm this?^^

Sorry to raise this topic.

A tech from the Snom support told me that Snom phones can lookup Contact name from the phone's address book. We talked about Snom phones with Asterisk.

Many thanks,
Michael

It appears you have more information on the subject than I do. Did they tell you how to turn the feature on, or should it work out of the box?

I tried it back in November when ovana asked the question, and my phone displayed only the number. It was possible to turn on displaying a name from the SIP From header. The phone didn't look anything up using its internal directory.

Hi Filip,

Well Snom support just told me that Snom phones can both lookup name in LDAP directory and internal address book during an incoming call. It will prioritize LDAP first then internal apparently. Only info I got.

I tested also, via connecting Operator to my Connect LDAP server for the provisioned phones, but phones still cannot match the name with the incoming call number.

Here is my Snom 720 display settings:

The results:

While the contact for this phone number is correctly registred in both LDAP and internal directories.
See bellow:

Here is the SIP log:

I can't really help you much as I am not a snom support person.

Your findings exactly match mine. I remember setting the "Number Display Style" to Name+Number, I also had entries in both LDAP and the local directory. I was able to look the number in both directories to dial it out. Unfortunately, when a call came in, all I could see was data from the SIP INVITE packet.

A funny thing is that if you create a contact in the phone's directory, assign it to a group for example "Friends" and then assign a different ring tone to that group, then when calling in, the phone will ring differently. So the phone does find the contact in the address book, but doesn't display it on the screen.

From my point of view the feature is either broken, or something else has to be configured on the phone to display the information.

One last thing, if you use Kerio Connect as the LDAP server, the feature won't work. The implementation of LDAP in Connect is not complete and searching is currently possible only by name and email address, not by phone numbers.

Thank you very much for your time Filip!

I have also found the same funny thing regarding different ring tones for groups. Something must be broken somewhere with the displaying names... Assuming that it works with Asterisk (I did not test it) it should works with Operator, right?

I will try to reach Snom support or at least their forums. And I will keep you in touch if you are curious and also to help others Kerio's partners.

I got a solution from Snom support.

You have to set "prioritise_asserted" to Off in the XML phone. Apparently Snom phones are looking for the P-Asserted-Identity header first by default which conducts to a bad behavior. So now my phones are able to match the number from my internal address book contact name Smile They still cannot lookup from my LDAP directory tough, but I guess this something about using Connect as LDAP.

I hope this will help someone.

Great discovery, thank you for sharing!

Searching in Connect currently does not work. However, better times are coming, the next major version of Connect is going to support it.
