First you need to set up a route pattern to your remote site. Let s say your DNs are 7xxx and your remote site is using 6xxx.

set up a route pattern 6xxx and select the trunk Route List in it.

1- Include the Partition of your Route pattern (6xxx) in the CSS of your phones.

2- See if there is any pre dot or anything related in your Route pattern

3- Ensure that the route list on your RP is correct (ie Trunk Route List)

4- on your remote trunk-> Inbound call -> CSS

check if this css include the Partition of your phones.

if all this doesnt help. use Dialed Number Analyzer (https://ip/dna) select trunk and see what the results are. Activate Traces on both callmanager (SDI, SDL). Use a sniffer on your phone and see if he is sending packets to your remote CCM.
