VG224 Calls within itself

Hello

 

I'm not sure how to describe this, perhaps it's a feature however I'm currently experimenting with a VG224 and have it set up with our Asterisk PBX via SIP.

 

It's all working perfect however I've just realised that if I have a phone in port 0 and a phone in port 1 when Port 0 dials the extension for Port 1 the call routes within the VG224 rather than going back to the SIP server then back to the VG224.

 

I can see how handy this would be however we need all calls to go to the PBX for call logging and other features (such as forwarding etc)

 

Can anyone explain how to configure this?

 

Thanks

Hi Campbellj1As per my

Hi Campbellj1

As per my understanding the analog ports on the VG is just acting like a  FXS ports on a voice gateway.
I believe you might be having dial-peers for the two analog ports on the VG , so when the analog phone on 1st port calls to the analog phone on 2nd port , the call comes in through 1st port using the incoming POTS dial-peer and then the call is sent to the 2nd port as per matching the dial-peer pointing to the second analog port.
Hairpinning of call.

Regarding your requirement where you need to send the call to the PBX , we can play around with the dial-peers,
we can use higher preference to the voip dial-peer pointing to the PBX then the pots dial-peer pointing to the 2nd analog port, and so the call would reach pbx .

Hi,If you are making call

Hi,

If you are making call from port 0 to port 1 by dialing 3013, it is going to take Dial peer 11, which has most number of matched digit (matched digits 4), rather taking DP 100 (matched digits 1).

dial-peer voice 11 pots
 destination-pattern 3013
 port 2/1

dial-peer voice 100 voip
 destination-pattern 3...


By changing the DP confgiration as below, DP 100 has more preference than DP 11.

>dial-peer voice 11 pots
> destination-pattern 3013
> preference 1
> port 2/1

>dial-peer voice 100 voip
> destination-pattern 3013


But, incoming call from PBX will loop and will route back to PBX. To avoid,

>Config t

>dial-peer cor custom
> name a
> name b

>dial-peer cor list inPBX
> member a

>dial-peer cor list outPBX
> member b


>dial-peer voice 100 voip
> destination-pattern 3013
> corlist incoming inPBX
> corlist outgoing outPBX

If you apply the above configuration.

++ if the extnesion from port 0 dials port 1 by 3013, it will take DP 100 VOIP and send it to PBX (by default DP has highest preference, 0)
++ If the call is coming from PBX, it will take inbound DP 3013, because of 'destination-pattern 3013'. But, it will not select DP 100 as out going DP because of COR configuration and it will use DP 11.


Thanks,

Can you post your VG224

Can you post your VG224 config? You probably have to use class of restrictions on the VG224 to send calls back to the SIP server and back to the VG224.

Hi,If you are making call

Hi,

If you are making call from port 0 to port 1 by dialing 3013, it is going to take Dial peer 11, which has most number of matched digit (matched digits 4), rather taking DP 100 (matched digits 1).

dial-peer voice 11 pots

 destination-pattern 3...


By changing the DP confgiration as below, DP 100 has more preference than DP 11.

>dial-peer voice 11 pots
> destination-pattern 3013
> preference 1
> port 2/1

>dial-peer voice 100 voip
> destination-pattern 3013


But, incoming call from PBX will loop and will route back to PBX. To avoid,

>Config t

>dial-peer cor list outPBX

If you apply the above configuration.

++ if the extnesion from port 0 dials port 1 by 3013, it will take DP 100 VOIP and send it to PBX (by default DP has highest preference, 0)
++ If the call is coming from PBX, it will take inbound DP 3013, because of 'destination-pattern 3013'. But, it will not select DP 100 as out going DP because of COR configuration and it will use DP 11.

That looks great! - I wont be

That looks great! - I wont be back at the unit until tomorrow so will try that and let you all know.

 

I do have a little query tho.  Changing DP 100 from 3... to 3013 will then stop other 3xxx based numbers being dialed from the gateway to the PBX.  We have (at the moment) 50 IP handsets fed directly from the PBX that are all assigned 3xxx numbers.  How would Port 0 reach these?

 

Do I have to create another DP and put in 3... however doing this effectively undoes what you suggested?
