So, does it mean I have one phone number with 5 lines? I can talk to one caller while the other 4 callers can be put on hold. I think I am still not sure the benefit of having multiple sip reg.
Another question, for VOXbasic (0 sip reg) I can not answer any incoming call. all incoming call will directly go into voice mail. I can only call out. Am I correct?
Thanks
