Re: Grandstream GXP xxxx IP phones are now preferred phones
Yes we worked a lot with Grandstream and interop is going very good.
of course build quality comes into question - it is the focal point. The phone needs to be upgraded to the latest firmware - then you will start seeing results.
When 3CX Releases a new version, the documentation that comes out with it should be read. The version number is printed on the guide. Failure to do so will result in a lot of tampering and you will feel like you are walking in the unknown - not knowing who to blame - whether 3CX, the phone or something you will be doing wrong. Then frustration starts to build up.
So please read what we publish. Also we are monitoring constantly to help you guys out.
Another version was released shortly after - Download again

Build version 18686_1567
This version will detect the phone and after detection, select automatically the appropriate template for you. So you will not have to select the template yourself. Just right click on the ,multicast entry in the phones page, Add extension and press ok. Or add existing extension and press ok. MAC and template will be selected and phone will provision.
