SNOM M700 Make Call Outbound

[AKCc]

Hello,

We have a 3cx (version 16.0.910 Pro on a NUC W10 PRO)
and we have 18 X SNOM DECT M65 (V450 B05), 6 X M700 (V450 B08)

Currently we have problems with the make call function in the 3CX client Windows with SNOM M700, DECT phone calls out, conversation comes to a standstill, but audio from the DETC phone is not transmitted externally. internally DECT phone calls everything goes

SIP trunk is: Telekom SIP TRUNK PURE

Has this already working fine, no more now ? or it has never ?

Do you passes green, firewall checker?

PBX and phones are on same LAN ?

Have you tried to enable, PBX delivers audio on SIP trunk?

hi,
It worked already, but we recorded the update 3 days ago
The funny thing is, we talk on the phone directly without the 3cx client, everything goes
firewall checker YES (OK)
PBX and phones are on same LAN ? YES
Have you tried to enable, PBX delivers audio on SIP trunk? YES is ON

 

[AWS2P]

which update are you talking about? PBX v15.5 to v16 SP2?

any messages in activity log? is it in verbose mode?

Could this possibly be a Codec issue, when calling externally? Have you compared the Activity Log of an external call using Make Call, and one made directly from the phone?

Hello,
Have tried it again
and found out who you put the conversation on hold and retrieve the audio connection to the external participants is back and it works fine??

which update are you talking about? PBX v16 to v16 SP2?
any messages in activity log? is it in verbose mode? NO

Hi @AKCc

Do you use Make Call on CTI mode via the 3CX client if I understood correctly?

This a a known limitation on the Snom DECT, we don't support this function so you might not get the behavior you expect on these devices

Can the phone make calls and send audio if you just dial a number directly from the handset?

Can the phone make calls and send audio if you just dial a number directly from the handset? Yes it works fine
if we call internally via the 3CX client it worsks fine

During the make call event, before the other side answers, do you hear music on hold?

You can go to the extension that is assigned on the snom base, and under the extension's options you have the Troubleshooting box. Which boxes are ticked there now?

 

[AKCc]

Troubleshooting
Potentially overcome compatibility issues with old/incompatible phones with these options
