Cisco 4331 does not route DID calls according to translation rule

kilias

Dear All

 

Recently we have migrated our company's voice gateway from 2911 to 4331 ISR. After dealing with

the new configuration parameters regarding the PVDMs and their position on the router (NIM card or motherboard) depending on the task required, we got it to work. However, the DID function behaves

weirdly! Despite the fact tha there is the following translation rule in the gateway's configuration , the only extensions that will not work are the 333 and 331. The provider is sending 3 digits through the PRI and only when those digits are 333 or 331 are not matched with any dial peer.!

The IOS version of the router is Cisco IOS XE Software, Version 03.16.04b.S and the dial-peer 

shown points to the CUCM. Has anyone seen any similar behaviour??

Please advise.
