Anyone here still using Snom phones? Incoming call glitch when using Edge Server
I'm noticing a glitch that is happening with our older Snom 710/720/D725 phones, doesn't affect our Audiocodes phones. I believe it is related to STUN / ICE. When we have an external user that is connecting via our Edge Server (either a remote IP phone or S4B App) and they call an internal extension where the user has a Snom Phone, the audio will drop out after 5-10 seconds. If the internal user with a Snom phone calls that person back, the audio is fine so it is only a one-way issue. Anyone dealt with this issue before?
incoming caller ID with Response Group showing number from previous call (PSTN only!)
Dear Community, we are facing a issue since about 11/2021 that incoming calls through RGS showing the false number. users only get the last telephone number from the previous call with new calls. all log files (like reporting database, or local s4b logs) are showing correct telephone numbers to the calls. only the S4B Client itself shows the previous caller id on an active call. the "standard" troubleshooting steps are already done (like clearing cache, etc...) - but this does not help. the problem seems similar to following threads: https://docs.microsoft.com/en-us/answers/questions/278753/incoming-caller-id-with-response-group-showing-sam.html https://docs.microsoft.com/en-us/answers/questions/520062/caller-id-issue-when-a-call-is-received-to-a-respo.html does anybody have similar issues...? or better, are there some solutions? overview: S4B 2019 Standard with May 2021 Update Office 365 semi-annual channel (so version 2021) s4b client: 16.0.13801.21148 We will try to update to the latest S4B Server Update (12/2021) because there are many fixes... but there is nothing in the change log which indicates a fix for this issue. Thanks!PSTN callers can't hear us
1. Teams Only organization w/Phone System/Calling Plans 2. Polycom VVX VoIP phones (latest SfB online certified firmware) When someone calls in, the Polycom phones and Teams apps that are logged into that account ring, but when we answer one of the Polycom phones, the person calling us cannot hear us. We can hear them. This happens about 3/4 of the time, but not always, and with seemingly no pattern. It doesn't seem to happen when answering using the actual Teams app - only when using the Polycom phones. I've checked out our firewall settings and we are not blocking any of the documented ports or ranges of ports that need to be open, and there is nothing in the actual call log that indicates something is going wrong. I'm at a loss as to how to even begin troubleshooting this. Any advice as to where I can look for clues? Thanks, Bob
Polycom VVX 411 Signing out Users at Random
Hello, We are about to roll out Polycom VVX411 phones using SfB but in our testing users are getting logged out seemingly randomly between 7-30 days. They do get an error "Exchange authentication failed. Sign out and sign in again." on their Polycom phones about 1-2 hours before the phone actually logs them out. We are running Polycom UC Software version 5.9.3.2857 We have MFA enabled for our end users also. We are using SfB and Exchange online, nothing on-prem. Has anyone seen or fixed this issue in their environment? Thanks!Caller ID issue
Hi there, we've got an issue with multiple tenants/customers with their outgoing callerid. I've created a new CallingLine identity and assigned them to the users, using PowerShell. Reason? The customer want’s to use the company’s main phone number for outbound calls. But when making outbound calls to varies Dutch providers, the main phone numbers is’nt showing up, but the personal user number is. When making calls to other Skype for Business users, the main number, does show up. -I’ve removed the calling plan, and created news one’s but the problem remains. -When assigning Anonymous callerid, is works perfectly. -We use PhoneSytem, cloud only with Office 365. So no hybrid environment. I’ve had contact with Microsoft support and with the Skype for Business porting desk. They both respond the same. The issue is not Microsoft it’s problem, but lies with the CNAM of the Dutch providers. I’ve tested it by making calls to Vodafone, KPN and T-mobile. All gave the same result. Not the main phone number is showing up, but the users personal number. Anyone else experiencing this issue? Microsoft is using Colt Telecommunications, perhaps i need to ring their doorbell...
authenticating with an access token
Has anyone tried authenticating with an access token (using -AadAccessToken or -MsAccessToken)? The old version of New-CsOnlineSession had an -OAuthAccessToken param, which accepted a jwt with the PS permissions in the scope, which one could obtain silently, and so avoid login. New-CsOnlineSession has been dropped and the SfB Connector is end of life in July and Connect-MicrosoftTeams does appear to support token for the telephony functions.MS Phone System - SMS texting?
We have a number of field personnel setup with Teams/PSTN calling plans. They assumed that their PSTN number would be able to send/receive SMS text messages to interact with people outside the organization, but this doesn't seem to be the case. (Apparently RingCentral supports this?) We just had one field sales rep complain that their lead had been texting her, but she never received the text messages. Of course we don't want to share personal mobile numbers with business contacts, and having a separate PSTN number and Mobile cell #'s just to support this seems excessive and old school, but maybe that's the only solution. Are there any plans to support this type of functionality? I don't necessarily care whether it's Teams or Skype for Business client based - but the ability to interface Microsoft Phone System PSTN with SMS is what we need. I see some third party products that give you the ability to text from SfB, but they do so by assigning you a dedicated additional telephone number - clearly not the solution that would work for us. Thanks in advance! Bob
SIP trunk translation issue
Hello, I am using E164 format to call outside, I need to add 99 before full number ( 99+4412345678), I applied the rule on Trunk configuration, however when I make the call I still see +4412345678 without 99 ( I am using Wireshark on mediation server). What I am doing wrong ?Setup PSTN Conferencing in Microsoft Teams
Microsoft just released Teams PSTN Conferencing service right before Microsoft Ignite. First of all, ensure that you assigned PSTN conferencing license(s) to user(s) Login to Teams Meetings > Schedule a Meeting http://social.technet.microsoft.com/wiki/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-05/561745.1.png 4. Setup a new meeting, add attendees as follow. http://social.technet.microsoft.com/wiki/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-05/87273520.3.png For now, you cannot invite external users as attendees in Teams yet like you can in SFB Meeting Invite, I believe you can do that in soon future. So, if you need to invite external users, just copy the invite message and email them. Attendees received meeting invitation email as follow, http://social.technet.microsoft.com/wiki/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-05/02500.4.png Meetings > click on meeting invite and Join button. I invited two users, one user is my internal user who received the invite email, I manually copy the invitation email and send to the other user, who will join the meeting using his mobile/phone; both joined the meeting, you will see a user is using his mobile number to join and while my internal users use teams client to join. The external user called +6531570124 (Toll) number to join the PSTN conferencing. It's surprising to take note that I cannot join Teams meeting using my SFB client though I can see the invite in my SFB client's meeting calendar, when I click the meeting link, it brings me to either use web browser or use Teams client. http://social.technet.microsoft.com/wiki/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-05/56804.5.png It’s also noted that I cannot invite external users and dial telephone number -- yet. http://social.technet.microsoft.com/wiki/cfs-file.ashx/__key/communityserver-wikis-components-files/00-00-00-00-05/4621.6.png
PSTN calls drop with-in 15 - 30 mins with Audiocodes SBC
Hi Community, Recently, I have come across a scenario worth sharing. PSTN calls drops after 15 mins or 30 mins with Audio Codes SBC or Gateway. This can be related or occur due to numerous reason, however if everything is in place (Network to Configuration) and still the call fails, then you can try the below and if it makes the difference. User makes PSTN call > the flow and connectivity is established > after 15 or 30 mins you see BYE message generated resulting in call drop. changing/modifying the "RTCPActiveCalls" and "EnableSessionTimer" may help or simple does't make any difference. Upon isolation, found that issue is mostly triggered due to a setting in Audio Codes S.B.C "Reset SRTP Upon Re-Key" is enabled (usually disabled by default) By going in to the IP profiles > disabling the setting in AudioCodes the issue was resolved and calls no longer were dropped. P.S - This solution may or may not help you (no harm in trying), But its best recommended to contact support and take assistance if needed 🙂
