I have a general question about DID best practise.
In the scheme "CUCM <ip> ROUTER <t1/e1> TELCO PBX <cloud> PSNT subscriber"
where is the best practise to perform a DID translation (while incoming
call from PSTN subscriber is receiving):
- on the router under voip/pots dial-peers through translation profiles/rules ?
- on the cucm itself by matching the whole DID number into route pattern ?
By the way is it possible at all to match incoming DID number into CUCM's route/
translation pattern or they are only designated for outbound (from CM Cluster) calls only ?
- DN no: 200 - 209
- DID no: 5551-23x (coming from PBX, only the last 3 (three) digits are significant)
dial-peer 2 pots
incoming-called number 555123.
dial-peer 1 voip
session target ipv4: <cucm_ip>
translation-profile outgoing PSTN-CUCM
voice translation-rule 200
rule 1 /^23/ /20/
voice translation-profile PSTN-CUCM
translate called 200
a. create route/translation pattern 555123X
b. do the neccessary called number translation based on transformation fields
Thank you very much.
