One of our clients is using a Grandstream GXP2000 with an attendant
console. We have used the same phone with past clients successfully
however this particular operator processes around 200 calls a hours and
the GXP2000 for sure does not like the quick line shuffling and call
volume. We get the following problems randomly:

1. menu stops working
2. transfer key stops working
3. Line 1 LED gets stuck
4. Voice 'gaps' (blackouts) for 4-5 seconds
5. The phone also completely locks up regularly
6. ping response goes from 8ms to 3000ms (after which the phone locks
up)

Wondering which operator phone would work best. I have the following
choices:

1. Linksys SPA 932/962 with attendant console
2. Polycom 601/650 with attendant console

I cant confirm online whether the BLF functionality will work with
Asterisk 1.2.26. Is somebody using either of these phones in a high
volume environment successfully?

Thank you.

Your problems reflect what grandstream phones do.

I have been using a Polycom 650 with 2 sidecars as well as 601 with no
problems, we don't do paging, but the 650 does around 300 calls an
hour. With no problems.
Asterisk 1.2.x does support BLF. Earlier versions of 1.2.x would lose
subscriptions on a reload, which meant rebooting the Polycoms, but it
was fixed somewhere around 1.2.1x not sure exactly.

We have been marketing ipPBX systems based on asterisk for 3+ years.
For the last year we've been placing Aastra 57iCT with 560M sidecars.
Our attendants like the idea of a cordless handset so the attendant can
go to the copy room, etc. The LCD based sidecar means you can keep it
up to date without marking up paper strips. We deploy Thirdlane PBX
Manager which allows us to setup the BLF (busy lamp field) via a web
interface.

For a receptionist, you generally want to go with a quality phone since
they're going to be the heaviest user of the phone system in the
building. (Inbound/outbound call agents may take/make more calls, but
their requirements are far more simple than the complex call juggling a
receptionist can do)

Go with the Polycom 601/650 with attendant consoles - the fact that the
display is LED and is automatically updated whenever the directory
changes is going to be a big plus here, and the sound quality of the
Polycoms outperform anything else on the market.

The only drawback is that IIRC the directory will have to be configured
through an XML file - the web interface will allow you to add entries,
however I have a sneaking suspicion that you /can't/ configure BLF
through the web interface.

We are using 57i + 560M combination as well... though we are not using the 57i ct... but the idea of giving them a cordless is a good idea.

The only downside to the Aastra 57i + 560M is that it can only subscribe to 50 extensions for BLF... i haven;t run into this cap yet myself, but I have heard others talk about it... I think it was a cap introduced in one of the newer versions of firmware... not sure though, and not sure why.

I'm running the latest 2.2 firmware on it... the addition of one-touch transfers in the last firmware was very nice so operator can transfer very fast, instead of having to do xfer->BLF key->xfer (for attended transfer), now they can just hit the BLF key for a blind transfer.

I'd find that very strange considering that the 57i itself has facility
for at least 20 BLF buttons and /each/ attendant console has facility
for another 60!
