Refine called number

Refine called number

V14.4 is updated to support a new feature in “dial plan” process. This feature is “refine called number”.

“Refine called number” can be used to refine called number before calls are routed to external lines or SIP trunks. It is the last chance to change called number to fit different requirements from peer VoIP servers.

For example, one of our customer has two VOIP accounts. One is from local provider, another is from international provider. These two VoIP providers have different number format requirements, and our customer only want to has one kind of dial plan for both of them. So we can configure “refine called number” to refine the final destination number to fit it. This scenario is illustrated below.

Scenario

As described above, there are two VoIP accounts, and users need dial “90xxxx” to make outbound calls. “9” is MSS default outgoing call prefix. “0” is required by local VoIP provider. At the same time, the international VoIP provider requires that the number format should be “0086xxxx”.

After compare these number formats, we can find that we only need change prefix “0” to “0086” for international VoIP account.

Step 1: configure an independent “outgoing group ID” for international VoIP account

Please click menu “Data / External line” and select the account to edit, then please click “Outgoing call” tab and configure following item:

Outgoing group ID = 1

Step 2: configure “number transition”

We need configure a new record to change preifx “0” to “0086”. Please click menu “Dial plan / Transition” to add a new record:

Transition ID = 1
Transition type = Replace
Start position = 0
Length = 1
Replace string = 0086

Step 3: refine called number for specific outgoing group

Please click menu “Dial plan / Refine called number” to add a new record:

Outgoing group ID = 1 <== defined in step 1
Called number prefix = 0
Transition ID = 1 <== defined in step 2

Here we maybe have a problem: the called number prefix is “0”, why? why not analyze “9” prefix? It is because that “9” has been deleted in “analyze called number” procedure and the number has been changed to “0xxxx” before it is sent to external line or SIP trunk, so we should analyze prefix “0” to refine final called number.

Two external lines, how to use specific one by dialing different called number prefix?

Two external lines, how to use specific one by dialing different called number prefix?

Description

One of our customers has two different VoIP accounts, for example (1) 1234 and (2) 5678. It is required to select account “1234” if users dial “9xxxx” numbers and select account “5678” if users dial “8xxxx” numbers. The final numbers should delete these prefix “9” or “8” and “xxxx” should be sent to VoIP providers.

Solution

We can use MSS powerful “dial plan” features to fit this requirement.

By default, MSS uses called number prefix “9” to distinguish outgoing calls to outsides. If there are several external lines and without any special configuration, MSS will select one of them in round-robin for each call. Now what we need do is to configure different called number prefix and select different external line for them.

Step 1: configure number transition

In this step, we need configure a record to delete number prefix “8” or “9” from called numbers. Please click menu “Dial plan / Transition” to add a record illustrated below.

Transition ID = 1
Transition type = delete
Start position = 0
Length = 1

Step 2: add new “Analyze called number” records

According to requirement, we need indicate MSS to analyze called number prefix “8” and “9” to use different specific external line. Please click menu “Dial plan / Analyze called number” to add two records.

Record 1: analyze called number prefix “9”

Dial plan = default
Called number prefix = 9
Route type = external line
Specific external line = 1234 <== use specific external line
Change called number = yes
Transition ID = 1 <== configured in step 1
Re-analyze after transition = no

Record 2: analyze called number prefix “8”

Dial plan = default
Called number prefix = 8
Route type = external line
Specific external line = 5678 <== use specific external line 
Change called number = yes
Transition ID = 1 <== configured in step 1
Re-analyze after transition = no
