R1 will receive calls from the POTS system, so it is necessary to make it handle these calls. In the real world the dial plan used is E.64 but here we have created our own dial plan and configured it on the Atlas550. The Atlas550 is configured to forward calls with 555-5xxx numbering destination to the PRI ports.

Use the voice translation-rule,voice translation-profile,translate called and rule commands to setup a translation. In this scenario, the inside IP Phones and regular phones have 5xxx numbering. The idea is split the 555-5xxx number, discard the first 3 digits and keep the 4 last remaining digits.

Note: The ADTRAN Atlas550 must be configured to forward calls to the PRI ports every time a 5555xxx number is dialed. Also, make sure you connected the CME Router’s PRI port to the right ADTRAN Atlas550 PRI port.

R1(config)# voice translation-rule 1

R1(cfg-translation-rule)# rule 1 /^555\(.+\)/ /\1/

R1(config)#voice translation-profile DID

R1(cfg-translation-profile)# translate called 1

R2 doesn’t have PRI/T1 connection to the POTS/PSTN. There is no need to issue commands on R2 here.

At this point R1 and R2 are almost ready but we still need to setup the dial-peers on them. The dial-peerwill handle both the outgoing and incoming calls.

Since R1 will receive call from the POTS system and from the CME software at R2, it is necessary to make it handle both kinds of calls. In order to accomplish this task, R1 will
