  2. Yealink T58 slow dial in CTI mode

  3. Yealink T58 and Plantronics CS540 and 3CX / Voice Quality

    Thanks for your reply. All Plantronics CS540 Sets in combination with Yealink T58A are involved. Swap headsets or replace devices near won't have any effect. Sound is low, sounds "compressed", like too far away from microphone.
  4. Yealink T58 and Plantronics CS540 and 3CX / Voice Quality

    Hi Community, since a few weeks users report low and bad voice quality if Yealink SIP T58A is used with Plantronics CS540 which is a wireless headset. The problem only exist if the headset is used. The handset of the IP phone delivers crispy and normal sound. It's difficult to say if this...

    Thanks!
  7. Given DN number cannot be used

    It seems that existing "Fax extension" is fixed to number 88 and can not be changed, see https://www.3cx.com/community/threads/change-fax-server-ext-from-888.57926/ That's bad. Any other solution to change fax extension available?
  8. Given DN number cannot be used

    Hello, due an existing logic I need the DN number "88" for its corresponding extension. I changed the number for "Fax over Mail Gateway" from 88 to 98 and restarted 3CX. But everytime if I try to create a new Extension with number "88" I get the error message "Given DN number cannot be used"...

    Hi Craig, thanks for your response and useful hints. Unfortunately there are road warriors and smartphone users connected to 3CX. Is ist possible to add Zadarma to a whitelist and keep 'SEC_IGNORE_USER_AGENT' on default settings? Best regards
  13. 3CX and Zadarma VoIP Provider

    Dear Fellows, 3CX blocks by default user agent "sipsak" which is used by several providers, e.g. from the affordable and serious zadarma.com. Now I removed the blocking entry for "sipsak" in 'SEC_IGNORE_USER_AGENT' field in Settings->Advanced->custom parameters. So far so good, Zadarma is...
  14. 3CX V12 / Galaxy S3 / Bluetooth issues

    Hi Andreas, thanks for your reply. The serious inconvenience is located in the fact, that users can't take the call by the switch on bluetooth device (e.g. Plantronics Voyager). I am technician AND user, so I use every day 3CX and its mobile capabilities. I had the big hope, that smartphones...

  19. No busy tone, no announcements - 3CX immediately disconnect

    Hi Folks, since I updated my Patton 4552 to the supported firmware 5.x I can't hear any longer the typical busy tone or announcements from phone carrier.

    Hello. thanks for your appreciated answers. It's true, there's really no way to simply ignore a certain incoming DID/MSN in 3CX. I solved my problem now by configuring the Patton 4552 with additional parameters like that: routing-table called-e164 IF_ISDN_0 route 123456...
