I'm having a lot of problems setting up the Granstream GXP2100 as an external extension (without using a local Proxy Server). The phone is not even registering.

If anyone has got this phone or similar working, would they be kind enough to post the config settings.

I've used the blog guide "Configuring External Extensions with 3CX PhoneSystem" for the basic config but there are still a lot of obscure (to me) settings that I may have not set or misconfigured!

Running latest firmware for the Grandstream (v1.0.1.66) and the 3CX running fine at external location.

Using Draytek 2820 routers at both ends. Mapping etc believed to be correct on 3CX side. No special mapping at Grandstream end. Fixed IP addresses at both locations.

Sorry, know it's a lot to ask but sure someone has it working - "Kevin" who wrote the blog must have done ;)

Thanks

But, is a registration attempt showing up in the 3CX server log? If it does, then what does it show? Any clues?

If it doesn't, then first run the 3CX firewall checker and make sure that all that passes. If all tests do pass, then I would suspect that the phone is not "pointed" to the correct IP / port.

Get the registration working first, then, deal with any audio issues that may crop up.

Unfortunately, I haven’t got the phone to register yet!

I’m pretty sure that is talking to the 3CX system (see log below), however, it doesn’t show up in the 3CX log (even in verbose mode).... which is worrying!

These were the basic Grandstream settings I was interested in my original post, to get it to subscribe.
Can’t deal with the other issues until that happens.

I am trying to find a Grandstream document on the log format shown below. Hope I’ve interpreted it correctly.

Any suggestions please or recommended settings for the GXP2100 in this configuration.

Thanks
Nilu

Hi Nilu,

Can you please tell us how you are resolving NAT? (STUN, port forwarding)

You can also open a ticket to Grandstream to get more assistance
