Testing voice translation rules To see how a voice translation rule applies to a particular string, use the command “test voice translation-rule {ruleset} {string}” Using Translation rules and translation profiles to manipulate the calling and called numbers Here is the lab setting: Mongi Shop is in Austin. Mongi wants to buy a bicycle from a local store. When he dials in the Sports Shop number (in Austin too), we need to make sure that on the gateway: the calling number is expanded to its E.164 format, which is the single PSTN number Mongi bought from Telco, the called number is expanded to its E.164 format too Using translation rules and translation profiles – we modify the outgoing calling number to a full E164 Local PSTN number –> apply it to the outbound dial peer – we modify the incoming called number to a four-digit internal number –> apply it to the inbound dial peer Let’s select the internal Mongi line: Then dial the full PSTN n...

In this article we will play with dial peers by setting different combinations between a source and a destination gateway. Here is the network setting: x5002 — Mongi Shop router — PSTN router — x4002 Before starting the lab, make sure you know the difference between CUCM wildcards and dial peer wildcards . In case you need a refresher on H323 configuration or packet analysis , then please read this post . Playing With Dial Peer Session Protocols case#1: one outbound call leg is H323 and the remote inbound call leg is SIP The call succeeds and it is a H.323 call: case#2: one outbound call leg is SIP and the remote inbound call leg is H.323 The call succeeds and it is a SIP call: So from both cases, we see that the type of session protocol used for outbound call legs follows what is configured on the outbound call leg, despite the difference with the remote inbound call leg. But, why does the terminating gateway still accepts inbound call legs whethe...
