set up to accept multiple external phone line connections at the same time

[linuk4]

Hi, any one can suggest me how to set up to accept multiple external phone line connections at the same time (only 1 external number with Twilio)? I am new, and using free version under 10 users.
basic setting up if all seems fine, you can call out, but only 1 can, other cannot at same time, or calling in only 1 allowed. I would like to have at least 3 connections at the same time with external lines, please help if anyone can advice?

Hi there, to accept multiples calls in your extension, please make sure to enable the parameter Accept Multiples Call within the Available Profile.



Using the 3CX Apps you will be able to handle multiple calls at the same time. If by chance you use a deskphone that supports multiple lines, then make sure that in the BLF tab you have the Line Keys




Within the sip trunk you may enable how many channels will be used.



Have a good day!

Hi linuk4 - just a footnote to mention for clarity, in case this is helpful.
Default behaviour on 3cx, an illustrative scenario,

you have one external# with SIP carrier which supports multiple inbound calls (say, 4)
your 3cx instance supports 4 simultaneous calls
you create an IVR to help automate call flow - dial 1 for reception, 2 for sales, 3 for support, 4 for accounts team, etc
then you have maybe 6 humans in the office / 6 EXT configured
you create a 'ring group' for EXT 101 and 102 and these 2 people will deal with inbound "reception' calls. So that inbound call > IVR > routes to 1 for reception > hits the ring group, EXT 101/102 can ring concurrent, and either may pick up the call.
in this scenario, caller one hits your phone# > IVR > routes to (1 reception) > EXT101 grabs it and talking to the caller-1
meanwhile, caller2 also calls the office, and hits office# > IVR > (1) for reception > now ext.102 may pick up the call, no drama
subsequently maybe another new external caller3 hits the office phone > chooses 2 for sales > this routes to EXT 103 which is your solo sales person. The call rings through and they can pick it up. etc.

ie, by default the call flows will allow multiple concurrent calls - depending on your inbound SIP trunk concurrency limits
and the 3cx "SC Simultaneous call" limits
and then - if a caller routes to an ACTIVE Extension## - by default it will dump to voice mail for that EXT inbound call.
and IF you wish - you can enable the "Accept Multiple call" feature that Alejandro_3CX - refers to above in this thread. And specifically that allows (designated EXT) - the ability to park one call and grab another - instead of having the inbound call flow to the VMBOX for EXT immediately. This could be desirable for a location with a very active "reception" and a need to juggle calls more actively.

but the baseline - is that - if you setup a few ring groups (or some kind of call seek/etc) behind an IVR - then most of the time, unless "everyone tries to call JonDoe at EXT 105 all at the same time" - then multiple calls will all just flow inbound fine, and your public phone# will happily allow this to happen, and it all works very seamlessly.
