I am very familiar with "traditional" ip PBX's (Cisco, HP, Shoretel). So far I must say I'm very impressed with 3CX's capabilities. In many of these other VOIP products, the default is that dialing 9 will grab an outside trunk, regardless of whether it is a PRI channel or POTS line. Then dial plan rules dictate whether you can call local, long distance or international etc. It appears that within 3CX, dialing a prefix number is not only not necessary, but may not be preferrable. Is this a true statement? Our installation will just have 3 POTS lines for telco access. So do I just need to build outbound rules for each of the desired capabilities? Also, how can I restrict a particular extension from dialing long distance? And lastly, where is the interdigit time out...even after dialing an internal extension there is a particularly long pause before the number is completed. Thanks in advance.
