PSTN SIP

The head office is currently making calls to the PSTN via third party (Astrisk system) through SIP trunk.

The remote site IP Phones and employee are on the field from the head office and they want to make the PSTN calls to their partner companies back in the head office country/people via Call Manager, How can I achive this , as I have assigned the default device pool to the head office people and other device pools for the remote countries as per their timings and local settings.

Any help will be appreciated.

Thanks
