Portech MV-372

UPDATE: This is old configuration you can try the new configuration in the post above

The Portech MV-372 gave me a lot of headache configuring it right. The configuration for Asterisk specified in documentations wasn't an option for me, working as extension, two dial stages while it works but come on, dial the extension, wait for signal, dial the number...
On the net i found some non-working configs so i had to spend 4 days trying to make it work as a Trunk and not as an extension.

Ok lets move on with configuration ;)

First we will configure the Portech MV-372 i believe this configuration will also work with Portech MV-370.

Login to your portech

• Route
  
  • Mobile To Lan Settings:
    Item | CID | URL
    0 | * | 100
    notes: in URL you put your extension of your asterisk you want call from mobile to go. It can be extension, ringgroup, ...
    
    
  • Lan To Mobile Settings:
    Item | URL | Call Num
    0 | * | #
    notes: URL will match the IP address that will allow to dial through portech, since my server is behind NAT i allowed all IP, haven't try to specify IP. Call num # will receive the number dialed from ip(soft)phone.
    
    
• SIP Settings
  
  • Service Domain
    Mobile 1 (Realm 1)
    Display Name: Sim1
    User Name: 1001
    Register Name: 1001
    Register Password: xxxxxx (choose a password)
    Domain Server: 192.168.x.x (you asterisk IP)
    Proxy Server: 192.168.x.x
    Mobile 2 (Realm 1)
    Display Name: Sim2
    User Name: 1002
    Register Name: 1002
    Register Password: xxxxxx (choose a password)
    Domain Server: 192.168.x.x (you asterisk IP)
    Proxy Server: 192.168.x.x
    
    notes: Username and registername you can change it to your needs just have a note of them since you will be entering those in asterisk trunks.
    
    
  • Port Settings
    Just make sure SIP Port for Mobile 1 is 5060 and
    SIP Port for Mobile 2 is 5062

Other settings are fine you may leave them as they are, only check Network (WAN) settings if you don't have DHCP or you need static ip for portech gsm gateway.

Dont forget to save changes (should reboot after saving)

Now lets move to Asterisk.

Login to your FreePBX/Trixbox and add SIP Trunk

Outbound Called ID: xxxxxxx (put you number here)
Maximum Channels: 1
go to Outgoing settings

Trunk Name: SIM1 (i have called it that way)
PEER Details:
host=192.168.x.x (your Portech IP address)
type=peer

Incoming Settings:
USER Context: 1001 (important must match username/registername at Sip settings of Portech)
USER Details:
type=friend
secret=xxxxxx (match SIP Settings password from Portech)
username=1001 (match SIP Settings from Portech)
qualify=yes
nat=yes
canreinvite=no
context=from-internal
host=192.168.x.x (Portech IP)

And then just click Submit Changes (don't forget the Orange bar on top after you make changes in your server)

Add another SIP Trunk for SIM2

Outbound Called ID: xxxxxxx (put you number here)
Maximum Channels: 1
go to Outgoing settings

Trunk Name: SIM2
PEER Details:
host=192.168.x.x (your Portech IP address)
type=peer
port=5062 (important - this is for Mobile 2, remmber Port Settings on Portech?)

Incoming Settings:
USER Context: 1002 (important must match username/registername at Sip settings of Portech)
USER Details:
type=friend
secret=xxxxxx (match SIP Settings password from Portech)
username=1002 (match SIP Settings from Portech)
qualify=yes
nat=yes
canreinvite=no
context=from-internal
host=192.168.x.x (Portech IP)
port=5062

Again apply changes.

We're almost done. Now to make this work we have to create Outboud Route, so click Outbound Routes
Put Route name as you wish, i have called it Portech_1 (since i will add another and will make it Portech_2)
Dial Patterns: i have put 049XXXXXX because i want only mobile numbers from the same provider to go through this trunk (through Portech) i mean i want to cut the costs right? But because you don't have my gun on your head go ahead and do whatever it suits you.

Trunk Sequence: i added SIP/SIM1 and SIP/SIM2
You can sepparate Trunks from OutRoutes if you have sim cards from two different providers, just create another Outbound Route remove one Trunk from trunk sequence of the first route that we created and add it to this new one.

Only thing you left to do now is click Submit Changes then Apply Configuration Changes and pray for this to work.

Hope it will work for you.
