analog gateways

[ppcs]

Hi,

I've been messing with a grandstream GXW 4004 (4 port FXS) at a customer's location.  Have had some issues, that may or may not have nothing to do with the device, but I'm not sure how much more I want to keep messing with it (and the customer).

I would love to hear about anyone's experience and preferences for audiocodes/mediatrix/adtran/patton/cisco etc with kazoo - googling provides plenty of opinions in general, but I haven't seen much discussion on the -dev/-users lists.

Appreciate any thoughts and opinions...thanks!

What kind of issues?

For the port stuff, can you configure a different RTP range for each individual port? I'm not familiar with the device so I'm not sure

We kicked this around a little via a ticket  - first issue we had with the grandstream was re-registration.  A network interruption would result in the GS not re-registering.  I opened a support request from Grandstream, very helpful responses, ended up removing the failover sip server setting.  This seemed to eliminate the re-register issue.  

But randomness on the first FXS port - inbound call answers but no talk path, meanwhile ports 2 and 3 ok.  Then, port 1 works ok for a couple days, then issue arises again.   Port 4 is configured for a fax machine, which, oddly enough, seems to be the only thing that works consistently.

I should and probably will open another support request with grandstream, get a PCAP etc. but I was hoping to get a general response of experiences from the list, good or bad, with their deployed analog gateways... trying to make an informed decision on potential future deployments....

It allows for a local RTP port (not range) to be specified per profile only, not by fxs port.  Signalling port can be specified by FXS. 

On mine, I use one profile for the voice ports, and the 2nd profile for the fax port.
