to cover each one in order;
1. Limit in Hnd. I believe the limit is 32 entries per HND, but you can create multiple HNDs and attach to a single TCRG.
2. If you are using T1 with ISDN, then you can have a total of 23 calls since there are only 23 channels. If you connect 2 T1’s then you could have 46 but only if you have enough voip channels. In the model type of tenor, there are 2 number. The first set says how many T1/E1 lines and the 2nd is how many voip ports, example a DX4048 means there are 4 T1/E1 lines, and 48 VoIP ports, so even though you could have 92 channels across the 4 T1’s (more if E1), only 48 will be able to go over IP.
3. calls to pbx/pstn. If you want different numbers to go to the different ports, then you would need to create a new tcrg and new hnd for each.
4. I do not understand this.
I think that you have many questions and it would be best to continue this through my email direct at firstname.lastname@example.org and we can further discuss my services to help you get this working.
