NEC SL2100 over an Engenius EnStationAC wireless bridge is having issues with Echo on the VOIP phones.  The phones are PoE powered from a Netgear GS724TP.  All equipment is brand new (Phones and network).  The cabling is not new and has not been certified.  The VOIP phones over the internet and not over the wireless bridge work fine.  Only the 7 VOIP phones on the far end of bridge have echo problem.  It is intermittent, sometimes not at all for several minutes.  All equipment has the latest firmware.  All phones are on G711u codec.  A massive amount of monitoring and testing has been done so far, and their is no latency (1ms or less) or dropped packets (0%) ever.  The phones also can monitor packet loss (0%).  The bridge has RSSI of -34, and for testing purposes was lowered intentionally to -45 and -50.  Bridge is 100% stable with no obstructions between the buildings (Clear line of sight).  I have used multiple 5GHz channels, and their is only one other 5GHz broadcast anywhere near this building (That channel is never close in frequency and has been adjusted for testing).  The bridge is currently in 20MHz (have used 80MHz also).  There is no data devices of any kind on this network (Voice only).  The bridge is NOT running in Green mode.  Engenius has been working with me on this and doesn't have any more ideas to test.  I have tested a phone directly connected by 3' cable to PoE switch, and problem exists.  We are going to test directly in front of the bridge (with PoE …

Polycom Soundstation 6000 not saving the Provisioning user information.  It saves the URL, but when you try to save the username and password, it "says" saved, but when you reboot or refresh the page, the credentials revert back tot the default one.  I also tried to enter it through the display (not the web UI) and same results.

I also tried to update the firmware, tried almost all of them and still same results.  Anyone have any other ideas?

A customer has recently had new phones installed that connect to a cloud based PBX.  They have a Draytek 2860 router.

They have sent me a document with the required entries in yellow (attached).

I presume they are asking that the firewall be opened up for those specific ports to the hostnames/ip addresses provided.

Can someone explain how I do this on th Draytek router

I am preparing to upgrade from ECC version 8 to ECC version 9.
In doing so we will need to upgrade the Agent and Supervisor Clients. When we upgrade the application on the client computers will our users have to log back into the agent application or will it remember their credentials after the upgrade?

I would also like feedback on any other gotcha's people experienced during this upgrade.

I recently moved a small Call Center from one location to another. They contacted me late in the game to help them get a new call center setup with very little time. This left me with Comcast as the only ISP to choose from that could install services within their timetable. We decided to go with their new Gigabit package, which includes their new Gb modem. The client also chose to go with Jive for their PBX needs and subsequently ordered 20 Yealink T40P IP phones. Let the issues begin...

Comcast's modem would partially default to factory settings once a week. When I say partial, I mean things such as factory internal Gateway IP and Subnet revert back; passwords are set to default, yet the SSID's are still what we created. Comcast claims that they can ping the modem but when I test connectivity inside the modem to the internet I get 0/4 packets received. This test was run by the modem internal troubleshooting software. The Uptime clock inside the modem says 17,500+ days, which is not possible since we have reset the modem within the last 24 hours and we have only had the service for three weeks. We have factory reset the modem, replaced it with a new one, and we are still having the Yealink phones not obtain an IP address, or they have an IP address but say "No Service", even after they have previously worked. Phones continue to drop off of the network in that manner, and PC's that are using pass-through are losing connectivity as well. No matter how many factory resets on …

We have an old Asterisk (v.2.x) phone server in our office.  I'm new to the system and need to change an extension number from a rapid busy signal to a working extension.  Also, we have several extension that simple hang-up when dialed (no tones of any sort).  How do we edit those extensions?

I'm new to Linux, but I've figured out how to browse directories and edit conf files.

We are in the need of a new phone system and there seems to be a mix of vendors pushing a hosted solution.  Has anyone upgraded in the past couple years to a hosted PBX solution and want to share the experience?  Of course the vendors not offering a hosted solution say to stay away from them they are not reliable.  I understand a lot of the bad from hosted is likely a so so Internet connection.  We have 100x100 fiber so I don't think that would pose an issue.  The big downfall I see is you pay for the hosted forever where an appliance based system, you buy it once and usually good for 10+ years.

Hello all,

I need to configure the Sonus gateway to route inbound calls to Toll Free number (main number) based on their area code to their particular response group on my Skype for Business server.

For instance, I have a response group for Chicago with DID 312XXXXXX and I have a main toll free number in which case all the calls come to this particular DID (800XXXXXXX) so I need to route all incoming calls from Chicago to the Chicago response group and the same thing for every other state.

I made the area codes already so all calls coming from Chicago state is directly forwarded to the Chicago response groups but the only thing I couldn't do is route all inbound calls coming to the Toll Free number to the response groups.

I would appreciate any advise on this.

Hi all, I am in the process of diverting an incoming call to a particular number on Sonus gateway from a number (Inbound let's say 5000 number) to an external PSTN number 9999 and I would like to do this on the Gateway's end not on the Lync client.

I was able to do this on the client end by simply entering the number in the call forward on client side but if I do this through the gateway with Normalization rule (using Transformation table) with the appropriate Signaling group and Call routing table I get no error in the logs if I choose one ITSP or I get Proxy Authentication Required if I choose another ITSP as signaling group destination.

How do I solve this authentication issue when forwarding calls from a number to another? I have been reading articles but mostly it says it has to do with sip manipulation but I don't want to manipulate the sip, I just want to forward call from a number to another.

I would appreciate any suggestion.
Thanks
