EHDU Status affecting Call Rerouting timer

[kwbMitel]

Here's a strange one for you.

I have an extension paired with an EHDU via the personal ring group.

To turn on/off the EHDU we use Remote DND. (Yes I know we can use presence but DND is less digits) (Yes I know I can use speed dials but let me get on with my point)

With the EHDU in DND, calls to the Prime extension rings 4 times then proceed to VM via Call Rerouting programming.

With the EHDU active, Calls to the Prime extension Ring 7 times an drop into the Cell phone VM.

Basically, the status of the EHDU affects whether or not the call routes to the internal VM.

Anyone have a suggestion as to why?

3300 = 4.2 SW

Couple of thoughts.

I guess you are remotely taking the EHDU in and out because the easiest way if you are at the desk phone is presence keys. Then its one push to change the status of the EHDU. I have keys on my phone to add/remove my desk extension, my cell phone via EHDU,a SIP client on an itouch, an extension on another 3300 via EHDU and a UCA softphone. I remove add members using the set keys or using the various location settings I have created on the UCA client on my blackberrry.

Is there any rerouting or forwarding on the EHDU extension number because whatever device "answers" first gets the call. Would not think the status of the EHDU would effect the call unless it had some king of routing. The call should ring the personal ring group until either it follows the rerouting or forwarding on the ring group or the forwarding or routing on one of the devices in the ring group kicks in. Hmmm.

The single biggest problem with communications is the illusion that it has taken place.

Yes I know about presence. I seem to remember mentioning that.;-)

No there is no routing on the EHDU.

I'm using personal Ring group - Again nothing added but members.

With EHDU in DND the primary phone will follow its routing.

With EHDU active the Primary set does not follow routing.

Regardless of whether I use presence or DND, the problem exists when the EHDU is active. The primary set does not route to internal VM

What happens if you enable COS Option "Hot Desk External User – Answer Confirmation" for the EHDU.

What type of trunks do cell phone calls route on?

Just a question to confirm................... Have you checked that the 7 rings is actually also presented on the deskphone.
The reason for this "stupid"question is the fact that I've had this here aswel. The mobile provider might be sending a connect message and the 3300 is told that the call is established. An other situation to look at is a possble progress message. a trace will show.

 

[sarond]

I have the problem that DoubleUT mentions and that is the reason I asked what type of trunks. We have mobile phone calls going through a dialer connected to the CO ports on the back of an MXe. When a call is presented via a PRG with an EHDU, these dialers must acknowledge a connect and the internal extension stops ringing and the mobile proceeds to ring and go to it's VM if not answered.

 

[kwbMitel]

Yes, the total rings at the desk phone is what I was counting. Not the ringback tones.

I think I may have an idea as to what is causing this but I have not yet had a chance to test.

I think the EDHU extension has a longer call forward timer in its COS.

In days gone by when we were working with hunt groups the hunt group properties would assume the COS of the first member of the hunt group.

I think what may be happening here is that the Personal ring group is assuming the COS properties of the EHDU extension by whatever means unknown. When the EHDU is available, the No Answer Timer follows the EHDU. When the EHDU is in DND the timer follows the desk set.

This is just a theory but it fits the facts.

When a personal ring group is called, the system will run the longest call forward no answer timer of the members that were called.

For example, a simple PRG with 2 members.
Member 1 has a Call Forward no answer timer of 5 secs.
Member 2 has a Call Forward no answer tomer of 10 secs.

When a call is made to the PRG and both members are ringing, the CFNA timer is set to 10 seconds.

If member 2 is in DND then the CFNA timer is 5 secs.

The reason it is like this is too allow for additional routing time in the public network.

From the Help file:

Class of Service of the group prime member is used for calls to non-prime members of the group. Upon answer the member's COS is used. For outgoing calls from a non-prime group member, the COS of the non-prime member is used unless name and number suppression to sets is enabled on the prime member, in which case the prime member's COS option applies. The following major COS area that affects PRGs is the longest CFNA timer of available PRG members.
