Controlling Caller ID with Cloud PBX

At the end of last month we were introduced to some additional Cloud PBX functionality around Call Queues and Auto Attendants. As part of these updates we now have the ability “To protect user anonymity, by allowing users to make outbound calls on behalf of an Auto Attendant or Call Queue”, which in layman’s terms means we can change a users outbound caller ID to be the same as a number that’s associated with an Auto Attendant or Call Queue. This adds further flexibility to the caller ID control … Read the rest

Skype Web App VS Skype Meetings App

Back in May 2017 we were introduced to the Skype Meetings App as part of Cumulative Update 5 – an alternative option for clientless users to join meetings through a browser instead of using the traditional Skype Web App. Lets refer to them as Web App (old) and Meetings App (new). Any meetings scheduled using Skype for Business Online now use the Meetings App by default. For on-premises users however, the Web App client will continue to be used until you specify otherwise. I guess the purpose of this post … Read the rest

Failed to Connect Live ID Servers

On completion of a Skype for Business hybrid configuration (and all things being well), you should find yourself in the luxurious position of being able to move users from your on-premises servers to O365, and vice-versa. “Failed to Connect live ID Servers…” is an error you might receive if you’re attempting to perform this ‘move’ action through the Skype for Business control panel rather than using the management shell. If you experience this issue (as I did) then you’ll see an error generated within the Skype for Business control panel … Read the rest

BT SIP Trunk – Calls Dropping After 2 Minutes on Mute

I recently ran into an issue whereby calls from a Skype for Business platform to the PSTN via a BT SIP trunk would drop after being on mute for exactly two minutes (120 seconds). In fact it didn’t matter if the call originated form the PSTN side either. The SIP trunk was terminated on an AudioCodes E-SBC Mediant 1000 running 6.8 firmware, and the problem could be replicated 100% of the time without fail. Anyone who regularly deploys and configures AudioCodes appliances will know that the vast array of configuration … Read the rest

Unified Messaging can’t save the PIN for mailbox…

I recently experienced an issue within a reasonably large organisation when trying to enable Skype for Business / Lync users for Unified Messaging. The Microsoft Exchange messaging environment was in a healthy working state, with no indications of any other problems. However when attempting to enable a user for Unified Messaging (regardless of whether this was through the Exchange management shell or control panel), the process resulted in “Unified Messaging can’t save the PIN for mailbox… there was an error accessing the mailbox using EWS”

At the same time the … Read the rest

Cannot Grant ReportsReadOnlyRole to User

Cannot grant ReportsReadOnlyRole to a User is an error that you might receive when attempting to deploy Skype for Business monitoring reports – a component that should always be configured alongside any Enterprise Voice deployment due to the wealth of information that it can provide on the quality and quantity of the communication sessions that take place inside your environment. Skype for Business monitoring reports are not deployed during the publishing of the monitoring databases themselves, and should instead be deployed desperately using the Skype for Business deployment wizard. During … Read the rest

PSTN calls dropping after 30 minutes with AudioCodes SBC

Consider the scenario – You have a Lync or Skype for Business platform sat behind an AudioCodes gateway or SBC. When placing an outbound call to the PSTN, the call establishes and flows correctly for exactly 30 minutes. At the 30 minute point you lose audio, and 30 seconds later the call drops completely. Peer to peer internal, external and federated calls work fine. If you run a syslog trace on the SBC, you’ll see that the BYE message is being generated by Lync / Skype for Business, so we … Read the rest
