Number Manipulations

28th March 201728th June 2019 Simon Birtles

With the exception of the Route & Translation Pattern Call Party Transformation, these transformations do not effect the dialled number or call routing.

SIP uses the Remote-Party-ID, From and Contact fields for caller numbers.

Directory Number Line Appearance External Phone Number Mask

When setting the External Phone Number Mask this full transformed mask is displayed on the phone also in place of the assigned DN. 79×5 and 9711 confirmed. It is used for the phones calling number identity (CLID) for external calls – only if the route pattern used for the outbound call has the option “Calling Party Transformations Use Calling Party’s External Phone Number Mask” selected as well which is not by default. SIP Invites have the transformed number for RPID, Contact & From fields.

Device Pool Call Routing Information

For H.323 & MCGP controlled gateways; SIP trunks do not carry number type info; but the Unknown option will work for all SIP calls.

Device Pool Calling Party Transformation CSS

Applies to all calls; i.e. both internal and external calls.

Device Pool Connected Party Transformation CSS

Unable to get this working with Called Party Transformation Pattern

Device Pool Redirecting Party Transformation CSS

Translation Pattern Calling Party Transformations

Translation Pattern Connected Party Transformations

Translation Pattern Called Party Transformations
As expected; this modifies the actual called number.

Route Pattern Calling Party Transformations

Route Pattern Connected Party Transformations

Route Pattern Called Party Transformations
As expected; this modifies the actual called number.

Device Number Presentation Transformation

(unsure – need to research if this is just mobility or not)

IOS Translation Rules – Calling Number (Outbound Call)

So take last 4 digits of the calling number and prefix with E.164

voice translation-rule 2
rule 1 /.*(….)$/ /441245001/ type any international
!
voice translation-profile PSTN-OUT
translate calling 2
!
!
voice-port 0/2/0:15
translation-profile outgoing PSTN-OUT
!
! or could be applied to serial or outgoing dial peer.

Same process applies to inbound and outbound for calling and called numbers

	Calling Number	Called Number
Inbound Call (Into GW From PSTN)	! voice translation-rule 1 rule 1 /(.*)/ /+1/ type international international ! voice translation-profile PSTN-IN translate calling 1 ! voice-port 0/2/0:15 translation-profile incoming PSTN-IN !	! voice translation-rule 2 rule 1 /96679(….$)/ /3001/ ! ! voice translation-profile PSTN-IN translate called 2 ! voice-port 0/2/0:15 translation-profile incoming PSTN-IN !
Outbound Call (From GW into PSTN)	! voice translation-rule 2 rule 1 /.*(….)$/ /441245001/ type any international ! voice translation-profile PSTN-OUT translate calling 2 ! voice-port 0/2/0:15 translation-profile outgoing PSTN-OUT !
