Hi All,
Quick one for the SIP experts - if I get a SIP trunk, with say 4 sip lines from a voip provider - am I able to just have one number associated with my trunk, with essentially 4 channels available to that number? i.e. if the one channel was in use, an incoming call to the same number would automatically use the next available sip line?
Is this a feature of the provider, or the ip pbx, and if the provider is this something that happens by default with the sip standard or is it something certain providers may or may not implement?

Thanks for your help.

The answer is both yes and no and depends on exactly what options the VoIP provider offers.

Multiple concurrent calls and multiple DDI's can be carried over a single SIP registration. Some providers will offer 2 calls per registration, some will offer more.

With WxC for example you can buy a DVX trunk and then buy but more "trunks" that allow multiple concurrent calls to be carried over that same number.

i have a sip trunk with 10 channels from callplus. calls to the main number keep coming in untill all 10 channels are full. i have an asterix pbx on our side - this handles the distribution of calls coming in on the trunk - all calls ring an operator hunt group, regardless of which channel they came in on.
