[arts111199]

Hi,

Please could You help me to strip some characters from A -number then route it to specified destination.
I have tried this way '
${caller}^\(.*\)\(374\)=;caller=\1
In this case A-number is 37411444444 but in outgoing invite From header is displayed with B-number.

Thanks in advance
