Call Forwarding & IP Trunking

[jamerein]

I have 3 sites each running a 200ICP CX controller with software 3.1.0.11. All 3 sites have IP trunking and ARS entries to dial extensions in all locations and loop start trunks at each location for local dial tone. Each site is fully automated.

Some of the users like to forward their phones to their cell phones. I did this with a speed dial containing 9 followed by the phone number of the cell phone.

If site A (Ext 550) forwards their phone to their cell phone and a caller makes a call into site B from a loop start trunk. The caller selects an option out of the auto atdt to call the user at site A (ext. 550). This call is made between the sites over the IP trunking. The problem is that because this set is forwarded to a cell phone the phone system at site B siezes a trunk off of itself and attempts to dial the phone number that the set at site A is forwarded to. This poses a problem for my customer as these sites are long distance to each other and the caller calling into site B actually gets a telco recording stating that they've just dialed a long distance call.

Does anybody know a way around this or have any ideas?

Are you sure in your description?

I would think that Site B in your example would have no knowledge of the phone number as it is programmed as a speed call on Site A. It seems unlikely to me that Site B would be able to dial the number.

Yes, my description is correct. It didn't make sense to me when the customer told me of the problem so I made a site visit to see it in person. I would have thought that the switch in site A would handle the ARS for the call forwarding but it is actually the one in site B.

I even attempted to make a special ARS entry for the speed dial that didn't use 9 to call out and when I called site B and selected the option for ext 550 in site A I got a recording from the voicemail saying that it was an invalid extension. This proved to me that site B is definatly the one handling the ARS.

I have a ticket open with Mitel on this and thier recommendations were to setup the IP trunks as tie trunks as I had originally been expecting only 3 digits on them. I have tried setting them up as tie trunks with no luck there either.

I still have to wonder if it isn't some sort of COS thing because if the set at site A is forwarded to voicemail the call correctly hits the mailbox.

It truly does baffle me.

if we break this down and hopefully I understand this problem correctly, can you call into 550 without it being forwarded to the cell?

 

[jamerein]

yes, that is correct. I can call 550 when it is not forwarded to a cell from site B's auto atdt and the call goes thru no problem.

 

[pandabear1]

ok you can call 550 thru the AA and connect to that extension from site B, can you call 550 when it is forwarded to the cell from within site A?
Also what is the option they dial to get 550 in the AA?

 

[jamerein]

Yes, and the call will go out to the cell on a trunk from Site A.

 

[pandabear1]

what have you designated as descriptors at site A for the incoming trunk and the outgoing trunk to the cell i.e. e&m tie or loop etc.

 

[jamerein]

Yes I can call ext 550 when it is forwarded to the cell from within site A.

The option they dial from the auto atdt in site B is 8. This is a transfer mailbox setup to dial ext 550. It really seems to make no difference if it's the voicemail or a user in site B dialing the extension the same problem happens.

check form 30 for interconnection, then form 4 option 21 enabled. In cos of vmail options 313 to 318 depending on your trunk descriptors.
