I have 2 remote offices connecting to the main office with h323 trunks. office 1 is ccme with a h323 trunk to the main office. Office 2 has a h323 trunk to the main office.
The main office has a sip trunk to a voip provider.
main office extensions 1000-1999
second office ext 2000 - 2999
third office ext 3000 - 3999
I can place calls between all the offices, however I want to be able to use the sip trunk to the voip provider in the main office from all of the remote offices. I have no idea where to start on this.
each office is running a 2801 router with ccme and about 10 users in each office.
Any help would be appreciated.
