IP Telephony

IP telephony (Internet Protocol telephony) is a general term for the technologies that use the Internet Protocol's packet-switched connections to exchange voice, fax, and other forms of information that have traditionally been carried over the dedicated circuit-switched connections of the public switched telephone network (PSTN). Using the Internet, calls travel as packets of data on shared lines, avoiding the tolls of the PSTN. The challenge in IP telephony is to deliver the voice, fax, or video packets in a dependable flow to the user.

Hello -

I'm looking for a solution for a portable conference phone. Currently I'm using a Polycom Soundstation that works with an analog line. The quality of sounds is obviously is not great so I was wondering if there is a more modern solution that could help with our needs. It would be for a room with about 20 people around a long table so I need to make sure there is decent range for them to be heard over the phone. I was looking into something like a Jabra Speak 710 UC Wireless Bluetooth Speaker device that would work with a cell phone but I'm worried about quality of sound over a cell phone connection pushed to a BT device.

Any help would be appreciated.

Skype sound not working.  The sound works on other applications no problem. I've checked the device settings - done the audio test - has worked fine. Am running both Skype for business and "ordinary" Skype but they've lived happily together until now.  Try the Sound Echo test - not a peep out of it...any suggestions. Thanks.  Skype version 12.1803.279.0
Thanks

Hello, I have a NEC model ip4ww-24txh-b-tel phone system in our office. We had a new line installed on friday by verizon, and I think something was reset on our phone.
When calls are made to our main line, it doesn't light up but if I pick up the phone the call is there. It can make outgoing calls, but incoming don't ring or light up.
Can anyone help me with this?

Thanks so much.

IP OFFICE SYS 1 and IP Office SYS 2 configured for Resilience with SCN route on the WAN port connection of IP500 V2 units at Release 9.0We need to add SIP Trunks to take the place of the PRI Trunks. There would be 46 SIP Trunk Voice channels on each IP Office System to replace the PRI Circuits. That is we are adding SIP Trunks for other than SCN Use. These will be
SIP Trunks to replace the PRI circuits and used for connection to the outside world for calls into and out of the IP Office Systems. Does anyone know of a reason that this configuration will not work. Are there any known problems using the WAN port for both SCN Channels and ALSO SIP Voice channels to the outside world?

Cisco call manager soft key templates do not appear to be applying to phones. I have created a new soft key template, have set up a test phone with the template selected both at Device and Device Profile levels and have reset/restarted the test phone. The result is no change to the soft key display on the test phone.

Also..... I have one (long standing) phone that has a different soft key button layout than others, but the soft key template config in both Device and Device Profiles is identical to all.

I have a feeling that there is something key I am missing, and perhaps overriding the soft key template config.

Can anyone point me in the right direction? I have phones to deploy that require a custom soft key config so I'd like to get this sorted out.

I had this question after viewing accessibility for a client.

I am starting off with a headset with two male connections (one for audio, one for mic) that plugs into a windows 10 laptop. I connect wifi to a residential connection. My family member who has hearing issues can not be present to test often. Right now I am not interested in security so firewall is not important.

All of my Office 365 users have a Office 365 Business Premium license.   We have Conference numbers and Conference IDs assigned by our Audio conferencing service. I see where it takes about using 3rd Party and Import/Export, though I don't actually see where you can enter in the 3rd Party Provider and Import the Numbers for the users.

If I select one of the existing Providers they all want a 6 Digit Conference ID, ours are all 4 Digit.

I would like to be able to use our existing Audio Conferencing system with Skype For Business.

Thanks,

Hey Experts, we have a Digium Switchvox VoIP Server. This past weekend our local power company had to upgrade our facilities power. We gracefully shut down everything Friday night, power was restored yesterday afternoon. This morning we have half of our phones not working as they cannot get an IP now. Our LAN and VoIP LAN are attached to our SonicWALL NSA2600, we have 3 Cisco SG500-28-p Stacked switches. What we have found so far is that any phone connected to the Master switch will not get an IP for the phone. Each desk has 1 Ethernet drop, that goes into the phone and the workstation plugs into the phone. The workstations all work fine to phones that don't work. We have rebooted the switches for good measure and nothing changes. Hoping someone can help shed some light on what the problem is.

Here is how the config on the sonicwall looks for the interfaces

I have a bunch of Polycom VVX400/410's, and more and more are becoming Agent phones.

I'm trying to find out if their is a way to setup a softkey or something that will easily show the user their login and possibly away status. For example I've seen on some manufactures the color or shade of the button will change when logged in. or even when away.

I really don't care what it is just something obvious. The best I've been able to do so far it turn on the screen saver and after a minute they can see their status. That of course hides everything else such as DND status, forwarding status etc.

We're using a cloud based provider but I have some pull so if I can find an actual solution (because they aren't) to doing this I can probably get them to customize some config files to make it work.

Any help is appreciated.

Thanks,

Kenneth Morrissey

I am looking to install a small low cost WIRELESS VOIP phone system for my church.  Requirements are simple - VOIP phones that will operate via the Church's 802.11 wireless network.  We have 2 incoming analog telephone lines.  Will need 5-10 telephones with voicemail on each.  Would like a desktop style phone in most locations (vs. a small handheld).  Recommendations please.

I'm looking for a guide or handbook on how to program phone buttons on the Avaya IP Office 500 v2.

I'm looking specifically for being able to program buttons to change an incoming call route (for out of office purposes) to change from one hunt group to another.

What I would also be interested in doing would be to have the ability to set the in service/out of service destinations of a specific hunt group and put it in to that mode, which could be an alternative to the incoming call route option above if that is not an option.

Thanks

We have a user who is moving to another city and we want to set up his Mitel phone so it is like he is still in the office using his same extension as before. I believe we have to setup a vpn so we can do without using teleworker feature on the phone but I am unsure. Looking for advice on how to go about setting up this user to have his phone work remotely. The only VPN we currently use is Cisco AnyConnect but just want to know what steps it would take to accomplish. Thanks in advance for the help.
