Yes.

bro,
What a small world. I know Tim, used to do some contract work for him. He is a good man.
Are you using SIP clients (softphones) at all? We are trying to get an * box working as an alternative to Skype. Any thoughts?

The most basic model Grandstream phones aren't too bad, other than the noted speakerphone issue. But the "4 line" model and the two ATA models routinly crashed on us. It was just an experiment at first to see if we could use it in house as a PBX. But what we really needed in a PBX is the line and station presence, which Asterisk and SIP in general isn't ready to do. So we went with ESI so we could support home and travel IP phones.

Put a call in to Grandstream, they do have a prog for the phones to reach out and grab their configs by MAC address. Not sure of the license on it, but I have a copy and it works fine. Lots of * scoffing here, but we use it as a feature server (voicemail, IVR) alongside our softswitch and it works like a charm.

to update this-
Grandstream phones can take their programming from any TFTP server. You do however need to correctly format the files. On Grandstream's website is a tool that will let you convert a text file into the correctly formatted binary config file.

Also yeah GXP2000 speakerphone sucks. If you want something bigger/better, try SNOM or AAstra, both make great phones with awesome speakerphones. More expensive per unit though.

Sounds like you need a radio backup for the Lite Pointe for that 1% downtime may be acceptable for data but not voice.

You can configure the switch to use the radio as redundancy.

And when you want to replace the a****k go Samsung with digital phones in the larger site and IP phones in the smaller site.

Update. LitePoint Replaced firmware in Laser, Rock Solid now. Astrik also working finePeople are bring in differnt phones Astra, Cisco, Snom.
Looks like if you want to do a lot of these you clone the drive of one already set up and make a new one and tweak from there.

So you had a port flapping issue with the lite pointe?

I'd be installing a radio backup becuase you may occasionally get problems with the FSO. You can get good carrier grade radios like RAD Airmux for under 5K after all you dont need all that speed for the VOIP side of things and youd probably find the data works ok especially in an emergency.

I have a customer that wanted to go FSO for a similar application I made them install radio first and we are now installing the FSO.

Has not even blipped since the end of march.
