Behavior is for about 1 in 50 calls, tends to happen in bursts 2 calls in a row, fine for a couple days, etc. The inbound call connects like normal, is transferred to park or transferred to another extension and the remote caller hears about 2 seconds of voice before the call drops.
The user could also be available elsewhere, such as through a voice mail service. Ok so then Voipo is saying busy here. How many active trunks did you purchase? Do you have this number defined in your trunk configuration for voipo?.

SIP response status codes
Most of the new range would be dormant initially. Of course I wanted to catch all the calls that were unassigned and send them off to a RGS. Here is where the plot thickens This seemed to work well in Lyncnow I find myself on and see a few interesting new features So I ring the unassigned number and low and behold, the gateway sends the call to Lync.
Lync sees the number as unassigned and does a trunk-to-trunk transfer sending the call back to the gateway. You know the rest of it right, the gateway sends the call to the Telco who sends the call back to the gateway and then back to Lync and before we know it all the SIP channels between Lync and the gateway are saturated. The caller simply hears what seems to be a longer than usual set up time and then the call fails.
So by now I am thinking why isnt my unassigned number config working If you needed Trunk-to-trunk routing a separate route should be built for the purpose. Removed the PSTN usages from the route, and voila! No comments:. Newer Post Older Post Home.
Subscribe to: Post Comments Atom.Busy on Busy is a very common and required feature that block a second incoming call to a user who is already on call. Caller will get a busy tone, callee do not get any disturbing alert or message, only a Missed Call notification in Calls History in Teams.
When I started to test Busy on Busy with Teams Direct Routing I noticed that the caller of the second call do not received a busy tone, instead he get a Call Failed error. Not so good.

I think that Comunicator is only a multiline user. Is not possibile to configure it in mono-line.Ramta israel
When an OC user is in a call and receives another call you can only accept the new call and put on-hold the first call or reject the new call. Another metod to reject the new call is: after you have received the first call, put in not disturb the comunicator. But if you want " Busy Here" message your problem is not resolved because Comunicator send an " Temporalily Unavalaible".
Can you update this thread? Have you implemented the RTM version and confirmed this is still an issue.? I created a small Crappy, testing code - as you can see - not fit for production, but ment as a proof of concept code only!

The Disconnect message starts the call session termination process. The Busy Here response is a client error response that indicates that User B's phone was successfully contacted but User B was not willing or was unable to take another call. The message indicates that the PBX is attempting to alert the user of the call that is to say, the phone is ringing.
User A hears the ringback tone that indicates that User B is being alerted. Therefore, SIP gateway 2 refuses the connection.Frida dump memory
The Service Unavailable response is a class 4 xx5 xxor class 6 xx failure response. Depending on which class the failure response is, the call actions differ. If SIP gateway 2 sends a class 4 xx failure response a definite failure response that is a client errorthe request will not be retried without modification.
If SIP gateway 2 sends a class 5 xx failure response an indefinite failure that is a server errorthe call is disconnected and other possible locations are not tried. If SIP gateway 2 sends a class 6 xx failure response a global errorthe search for User B is terminated because the 6 xx response indicates that a server has definite information about User B, but not for the particular instance indicated in the Request-URI field.
Therefore, all further searches for this user will fail. In that case a SIP failure response is sent before the Trying response. This section describes the call flows for gateway-to-gateway calls via a redirect server that have failed.
User B's phone begins to ring. SIP gateway 2 refuses the connection. The Not Found response is a class 4 xx failure response. If SIP gateway 2 sends a class 5 xx failure response an indefinite failure that is a server errorthe request is not terminated but rather other possible locations are tried. This section describes the call flows for gateway-to-gateway calls via a proxy server that have failed. The cause code indicates that User B is busy.
The Release Complete message from User B starts the call session termination process. A class 6 xx failure response indicates that a server has definite information about User B, but not for the particular instance indicated in the Request-URI field. All further searches for this user will fail, therefore the search is terminated. The SIP proxy server must forward all class 6 xx failure responses to the client.
The dark mode beta is finally here. Change your preferences any time. Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. Has anyone seen this issue? The thing to remember with SIP response codes is there are no hard and fast rules about which specific response code should be used in all situations. For example if the SIP notification server maintaining the subscriptions has a limit on how many active subscriptions it will maintain or if it's overloaded and doesn't want to process subscription requests for a while.
I'd have a closer look at the response and see if there is a Warning or any other informational type header. Also check whether the response is coming from the intermediate proxy you are using or the end server. You need to trace your server if possible to understand why it decided to send such an unexpected error code.

Korn Mar 14 '11 at Do you always get a failure when subscribing to the watchers list? Are you able to check the failure responses you are getting for more info like Warning headers.
Apart from that the best way to find out what's going on is to find out from the server why it's rejecting the requests by looking at its logs or whatever other mechanisms its got. I've asked ALU for an explanation as well. In the meantime, the response does not include additional headers.

Promoting, selling, recruiting, coursework and thesis posting is forbidden. Students Click Here. Hello gents! I've checked trunk to trunk transfers, restrict call off net also Thanks in advance for any suggestions. You have some CM configuration problem. Kyle, thanks for the input, I made a direct test call from the local facility, it went through just fine, I then figured that our CM was missing a route pattern in the all location table for this redirected calls, I added one route pattern for testing and calls are not getting busy signal anymore but still fail, I then took a direct call trace and had it compared to a redirected call and I am now noticing that the failed call is getting a area code prepended which makes it end up in a not found, but now I am getting a hard time figuring where it gets it from since both working and non-working are using the same route pattern and trunk group.
If the source is SIP and CM has no routing, it will use the proxy selection route pattern in the locations table. Is your core CM there? Does some route pattern have a prefix mark and NPA ? Why even send the 8 to SM?Pearson vue trick failed but passed
I suppose you could have steering codes in there if you have to. Or, if you're really lazy, just have the adaptation on your CM entity have a digit conversion adapter. What location is used to take calls out for redirected calls? Where does that 8 normally come from? And why the heck is the NPA ??? That's not a legal or valid NPA. I thought your dial plan might be a mess.
That in the NPA proves it! Who thought that was a good idea? Just duct tape it in the session manager adaptation and pretend none of this ever happened!
