  1. Yealink vs. Fanvil

    We have been a Yealink shop for the past 5 years. I started looking at the Fanvil line of phones a week ago for a new project. Curious if anyone would like to share their views on the two brands? Nothing specific that I'm looking for. Yealink has worked well for us with few problems. Fanvil...
  2. Handset with Many BLF/Intercom Keys

  3. Trunk Registration sending DNS name and not IP

To be clear this is partially an issue with the SIP...
  4. T46 Firmware Update - Things I Learned

    @cobaltit - I've been thinking of moving that way for future installs. What hardware do you recommend? Just something from Amazon like CanaKit?
  5. T46 Firmware Update - Things I Learned

    I've been getting away with not assigning individual listening or "Local SIP Port" for remote STUN extensions. Fully aware that it is not best practice. It seems that by checking "PBX delivers Audio" using the same port of 5065 for many extensions behind the same firewall it was working well...
  6. V16 Update 2 Problems with Yealink

    Answers below: -Server passes firewall checks. Same firewall config that I have on 10+ other servers. Running on Vultr. -Phones are all setup STUN, first phone on the system - no other phones provisioned or even setup in server yet so there could not be any NAT or port conflicts. -Unique ports...
  7. V16 Update 2 Problems with Yealink

    I have not dug into this any further as it was easiest just to roll firmware back and it works. I'll test and collect logs or packet capture in a few weeks when my schedule opens up. No time for it right now.
  8. 3CX FQDN TTL

    SD-WAN makes it all so much easier.
  9. 3CX FQDN TTL

    I agree. I've had this cause trouble in two cases: WAN failover with local server and remote clients Re-installing or moving instances in the cloud due for various reasons outside my control Even setting the TTL down to 1 hour would help quite a bit. I understand that they want to offer...
  10. V16 Update 2 Problems with Yealink

    Cloud Server I rolled the firmware back to 66.83.0.35 and it appears to work as expected. @3cx Please take note. Recommended firmware for T46S does not seem to work with update 2. I can provide more details and assistance if you contact me directly.
  11. V16 Update 2 Problems with Yealink

    Fresh install for a new customer. Installed 3CX on server yesterday. Go to provision phones this morning and I'm having trouble. 3CX Linux Version 16.0.2.910 Yealink T46S on recommended firmware 66.84.0.35 does not register. CSTA session fails so no BLF activity Server thinks phone is...

  13. v16 & Ubiquiti EdgeRouter - FW ports 10600..10998 full cone test failed (only)

    I just had this happen to me at a remote site. After turning off the ALG on the Edgerouter - make sure to save and apply the config after and then a reboot of the Edgerouter it all started working again.

    Had a client log into his own server today and push upgrades to his Yealink T46s and T42s phones. Latest firmware of 66.84.0.35. Right after extensions stopped registering from remote location. Took a while to figure out. The Edgerouter at the remote site had SIP ALG turned on. Worked fine...
  15. 504G DND button on v15

    Anyone able to get the DND button on a SPA series phone to work with v15? It was working fine on v14 and seems to be able to set DND but not deactivate DND profile. On v14 I had it synced with 3cx - phone would would dial *30 or *32 as necessary to toggle status. The DND softkey would also...
  16. Emailled Wav file won't play on Android
