  1. Sip trunks on both sides of an SBC

    Trying to use search, but SBC is too small for the search bar. Curious, I have 2 offices setup via bridging and each side has their own SIP trunks. I am considering doing away with one office 3CX and using SBC to bring it together.. I would still like to use the SIP trunks in the remote office...

  2. Comcast/ Xfinity SIP trunk

    Comcast SIP works perfectly. Comcast has a setup document for 3CX and certifies 15.5 for use with their system. I have 24 sip lines with them since 3CX version 14.

  3. Keeping 3CX Linux updated

    We know that the 3CX application itself is updated as we go along, but should we also be doing an APT-GET UPGRADE to keep the OS up to date. I am showing 44 updates needed

  4. Yealink T4x config file for SP6

    Starting at SP6, I notice in the Yealink t4x XML file the SIP-T46G is displayed as Yealink T46. There is no entry for T46G (it is identified UA-SIP-T46G with a name of Yealink T46). This is no problem if you going to configure new phones, but it it was selected as T46G from previous...

  5. Unsupported SIP trunk providers alert in 15.5 SP4

    In US, Comcast Business providing SIP lines fully supports 3CX and there are 2 certifiying groups in the US that have tested and certify that combination. Comcast Business is not a 3CX partner, so in that vain you would get a red warning. They provide two configuration examples, one is to select...

  6. T48G does not show as new phone

    Check the Blacklisted IP's. The IP for that phone might be there as when you experimented with the extension it could no longer authenticate. After so many authentication failures, the IP gets blacklisted.

  7. PnP Provisioning Issues

    This may seem wrong, but check this. When I "replaced" my server and decided to build from scratch, I could not get any phone to authorize and most did not show up as PNP. What happened was 3CX blacklisted the phones for to many authorization failures. I ended going into 3CX and whistling the...

  8. Easier way to change templates

    +1 - add a HQ location with 20 remote sites as bridges and it gets old. +20

  9. Bridge Phonebook Sync/Integration

    +1 The way I handle it for now is I have the phonebooks for each site listed in the phones directly.

  10. Sonicwall Help

    On the outbound NAT rule that is created by the wizard, go to the advanced tab and check the "disable source port remap".

  11. Comcast SIP trunk on premise

    Comcast will provide (usually) an adtran. Your enterprise manager will give you a form to fill out with the internal IP of your 3CX and what IP you would like the adtran to be (in the same subnet). That adtran IP will become the IP you connect to. 3CX is fully supported by Comcast. There is a...

  12. Questions on hotel system with analog phones in rooms

    Comfirming also that Comcast Enterprise SIP works great with 3CX, it is certified and supported in their system and they have extensive documentation available for setup. I have 32 lines SIP and Patton ATA for Fax. Works very well.

    Confirmed that editing the firmwares.json corrects the problem.

  14. Solved Issue since upgrade cp860

    I have the file CP860-38.81.0.10.rom in the directory, but the phones does not show as upgrade needed.

  15. Do phones with custom templates always show up in red?

    Multiple Phone books is easy - maybe limit to max of 3. Show them the default one for the #1 position, then give them an option for 2 or 3 more . If the customer is smart enough to know how to bridge and create multiple phone books, then they are smart enough to know how to build the URL, local...

  16. Do phones with custom templates always show up in red?

    Maybe for small installations, but any installation that 64 or above HAS to use custom templates - Multicast Paging, multiple phone books, etc

  17. Getting updates ?

    But then you get to chicken and egg problem. I decided to install a new phone that I haven't used before. I have no way of checking for the lastest firmware or template BEFORE I start any configuration process. There needs to be a way to "display all available"

  18. Yealink T4x template update - what changed?

    Found in the 62930 template.

  19. Getting updates ?

    The above should be an easy fix. In phones you are displaying the model, in this case SIP-T48G, so it knows to look for new firmware. While checking for firmware, check for the associated template.

  20. Custom Template: what if... ?

    I use WINMERGE to compare the 2 files. It will find the differences, then you have the choice to copy over just the new settings you need. Take a few minutes at the most.
