Hello,

I have a 3CX PBX where I have mounted a borne SNOM M900 + M65 DECTs (exactly 11). The problem I encountered is that when a call comes in on a call group using the DECTs, the DECTs are unable to answer the call even though they ring normally, any attempt to answer the call results in the call being terminated on that DECT, however, the call continues to ring on the other dect and there is still only one random person who can answer the call.
The M900 terminal + DECT are updated with version 5.30 branch 07, the codecs put in order are: g711a then g729, and on the 3CX side there is no anomaly (group setting ...)
I tried to put in the call group only 4 people respecting the number of simultaneous calls that can take the terminal but in vain.

I tried to mount onle 8 DECT in the borne in vain too


Have you ever encountered this type of problem with other customers, or any ideas on how to solve it?

    Hi,

    Not all the handsets will be able to ring at the same time, as you correctly corrected already, so you need to have a ring group which isn't bigger than the amount of free DECT channels when the call comes in (10 channels when using the M900 as a single cell).

    If even with a smaller ring group this is still a problem, like in the tests you already ran (8 handsets for example in the group and no handset with a call already ongoing) you can try and apply the parameters from the guide below

    What to do if there are no incoming calls on the M-series, when using 3CX

    If the problem still persists, please raise a private ticket with us if you are a Snom partner, or ask your reseller/distributor to do so for you.

    Thank you
