Mitel 5324 used at home and office is it possible?

[achri332]

Is it possible to have a phone setup to be used at both the office and via a home connection?

I met with our installer today and we were hoping to have it setup so for example if it was going to snow someone could take their desk phone home and work from home.

They weren't sure. I found these forums and thought maybe someone here would know, or have a method they used to allow it to function.

That depends... how do you get remote phones working? Do you have an MiVoice Border Gateway or just using port forwarding/DMZ to the MiVO250? And how trainable are your users?

Best case scenario, put the MiVO250 in a data center or hosting site and have all phones be Teleworkers to that. Then it wouldn't matter where they are, in the office, at home, on the road, etc. All phones would be Teleworkers in NAT mode.

Second choice, you have an MBG and trainable users... Users could take their phones home, place them in Teleworker mode and point them to the MBG. The MiVO250 doesn't need any changes.

Worst case scenario, you are doing simple port forwarding and would need to due 2 things. First, in the system configuration of each user change their NAT Type from Native to NAT -AND- have each user place their phones in Teleworker mode.

There are other options, depending on the number of people we are talking about... Can you give us a better scope? And are you willing to change phones?

Haven't done it yet, but it sounded like it would be just port forwarding.

It's only likely 1 or 2 phones that would ever possibly move.

Would it be possible to use something like loopback/nat hairpin https://help.ubnt.com/hc/en-us/articles/204952134-EdgeRouter-NAT-Hairpin-Nat-Inside-to-Inside-Loopback-Reflection- in order to handle it so the phone would always be NAT but the router would pass it back to the local side?

Can't change phones unfortunately.

Softphones could be an option for occasional use.

[achri332]

The phones are installed now, so I'll definitely be playing around with this. Softphone will hopefully be an option, waiting to hear about licensing.

Yes we take ours home in the event of snow, Port forwarding or have a VPN via router.

I'm trying to get the port forwarding working currently, anyone familiar with Ubiquiti Edgerouter? I started with a thread there https://community.ubnt.com/t5/EdgeRouter/ER-Lite-forward-group-of-ports-from-1-of-our-static-IPs-to-IP/m-p/2261744/highlight/true#M199048 but despite their help haven't gotten the ports for the Mitel to forward, has anyone else already done this?

achri332,

It may not be your router if you haven't setup the MiVO-250 correctly then it could be that. You need to tell the phone system what Public IP you are going to use for the phones or it won't send the correct information back to the phones to reply to.

Also, if you have a PEC on your system you will need [2] Public IP addresses to make it work properly or you won't get audio in both directions.

Thanks

I know that my vendor did go into the MiVO-250 and set the IP in two different places, so it should be right.

I don't believe we have PEC, our vendor didn't mention needing anymore than the ports forwarded. But I do have 2 public IPs, in fact I'm using our 3rd IP for the Mitel rather than the first IP which is used for general purpose.

[achri332]

I've got SA&D access now for my system, what places should I be checking to make sure our external IP is correct for external access?

System-->IP settings-->PPP IP Address and System NAT address
system-->Device and feature codes-->IP connections-->P6000-->NAT IP address

magnus,

This is the only one you need to change if you don't have a PEC in the system.

System-->Device and feature codes-->IP connections-->P6000-->NAT IP address

This is the address that is used by the modem if you dial in to it.

System-->IP settings-->PPP IP Address

This last one is used by SIP devices/trunks, but it is always good practice to change this one to the public IP address as well.

System-->IP settings-->System NAT address

Thanks,

TE

People still use dialup access to these things? I don't think I have done that since 2010 or so.

That said, why do you need to change this? We never did...

[achri332]

Okay thanks! It is set correctly so I guess it goes back to the port forwarding not being correct.

[magnus]

Here is a spreadsheet we use to confirm the correct ports are forwarded. Most of the ports in this system are changeable so confirm those are correct for your system.

I have run into issues occasionally with networking guys picking the wrong protocol and struggling for a bit.
