Hi Doug, if it helps, in Remote Settings for that extension:

1. check/turn on: Enable RTP Proxy
2. check/turn on: Symmetric RTP

Also in the Advanced Setting for the T22, have the "RPort"...

Thanks, Vahan. I will get arrange to provide the full log and forward when completed.

Is there a chance for assistance in this issue? The matter is becoming urgent and appreciate some comments from members who have experienced similar issue. Thanks.

We have two Quadro M8Ls with standardised Yealinks. The new one was cloned by restore with values (IP, names, etc) changed for the new site. The local IP phones worked well on the new M8L but the...

I have similar issue on my side with a new Quadro M8L, cloned from an existing M8L. The remote phones do register OK but unable to make calls (extension and external). We have 2 Quadro M8Ls and on...

if this helps:

assuming you have 4 DIDs via incoming pstn lines that are connected to your FXO ports with Routing, e.g. 5010, 5015. The 2 businesses would have 2 different Attendants configured...

matter is now resolved and perhaps it might be relevant to share observations with others. We had several "rejected by cac System capability exceeded " event messages. When this happens, an...

Hi hrant, we had our fair share of such attacks and I guess it is a universal issue for all IP PBXs. I am thinking that stricter control e.g. any 3 tries from an IP and that IP is disabled by the IP...

Hi,

Try the use of the Fail Over definitions in the Call Routing wizard. This would achieve what you want to do. When this routing fails, say BUSY or Network Failure, it uses the subsequent...

Hi Ashot, apologies, I estimated that time to be about that time-frame and on second look it is actually showing in the 7 to 8am slot for the incoming, outgoing and active calls that is displayed. ...

Have observed in Quadro M6L (ver 5.2.26) that the displayed statistics for FXO is showing earlier time for the intraday and other display. I have quickly checked with the call statistics and it...

Hi Peter,

We have implemented a number of Quadros to replace similar older PABX configurations and found that the basic 2 line IP handset works well for the average user with dependance on...

There are many options open to you from IP phones with 6 lines to 2 lines (or 1). In practice, most users only need 1 line but having additional lines can be beneficial depending on the role of the...

Suggest you initially keep the 5 PSTN lines for incoming calls and review to reduce after the M8L is fully operational and you can see the calling patterns. Having one IP PSTN (VoIP line) will be...

Not sure if this was the solution but when we re-booted the router at the remote side, the issue was resolved.

I am working on a Quadro M6L with 2 FXO PSTN incoming lines and 1 IP PSTN line. Had an observation on a Quadro M6L Call Statistics showing several Missed Calls from the PSTN port. The Quadro is...

Perhaps this is the same issue we encountered when working with this 6L product. You need to goto the Key System Emulation under the Telephony menu and deactivate the defaults for KSE. Then your...

Hi David,

Thanks for the guidance, explained simply what we need to do in this critical area.

We have tested a few Quadro systems during implementations and noticed that when we used a...

Hi hrant,

Many thanks, that worked after the suggested change.

Noticed that on the LAN, the Yealink IP phones, e.g. T28, T20 works well and gets auto connected when the MAC and line is defined for Quadro8ML (Version 5.27). However, I am beginning to notice that...

FYI, we have implemented on Quadro M8L two separate pickup groups for different sets of extensions numbering plan and it works well. When a call comes in, the correct pickup group number is dialed by...

Many thanks for the details and this is helpful to reinforce my understanding and perhaps other users.

It looks like the hackers understand the default prefix '8' that is created on installation...

Thanks. I checked and only entry was the default one automatically created for prefix '8' in CRT with no "Filter on Source". I have now updated this for 'PBX' Filter on Source.

For my better...

Best wishes for a great 2011 to All and thanks for all the comments and suggestions last year!

From the logs for "Unsuccessful Outgoing Calls" in Call Statistics, I was surprised that there were...

Like all the users, we have our fair share of such attacks. I have always tried to report such abuses and often get back responses that the ISP's customer's server had been hacked and now resolved....
