Need to use PSTN line with 3cx temporarily

[Cjackson]

Hi,

I have a client i'm looking at setting 3cx up for, we are due to set up the SIP trunks soon but their phone system is about to die and they want to move quickly, the problem is we have been quoted up to 6 weeks for the number to port and i don't think the phone system is going to last that long.

Is there a way i can purchase a device that will let me use the PSTN line in 3cx until the number has ported? and if so is there any documentation about setting it up?

Thanks in advance

CJ

Yes, you want a Patton FXO device (4112 JO FXO) if you have 1 BT line only.

There is also beroNet equivalents also, both are supported by 3CX for auto-configuration. I do however prefer Patton as they are stable and solid.

awesome thanks, is there a model that would allow for more lines? say 2-4 lines?

 

[eddv123]

Yes absolutely, the SN-4114 JO (FXO) will give you 4 lines.

They are all part of the 4110 series and will convert SIP to Analogue/BT lines:

Just make sure you DO NOT get an FXS variant, a common mistake made. FXS is for analogue endpoints such as analogue phones, FAX and ringers: https://www.patton.com/technotes/fxs_fxo.pdf

Hello @Cjackson
Check the following link for supported PSTN gateways with links to guides

Why not set up a SIP trunk with a temporary number, put a divert on he number you're porting and spoof outbound calls on the SIP trunk

How do you spoof the number? i have tested changing the caller ID field for an extension on our system but the call just fails, but this was how i was hoping to achieve this.

awesome, thanks everyone, a few good options here, i'll check if my trunk provider will help me with the number spoofing otherwise the Patton's look like good options.

thanks again.

While not supported, if you're handy... Good unit.

Dinstar has instructions on their page to configure for 3CX.
It has both FXO and FXS

Only $200. Nice for backup when the net goes down.

I concur with Trifif. We do this all the time. It allows you to move off the failing phone system right away, without having to purchase a gateway that will have little purpose in a few weeks. It should be noted, however, that many SIP providers will NOT allow you to "spoof" your outbound caller ID. I could imagine a scenario where a company wanted to give the appearance that their calls are coming form the "tax authority" for nefarious reasons. So you can appreciate why the carrier may require your outbound caller IDs be in their inventory. Nevertheless, it is not uncommon for SIP carriers to allow you to spoof your caller ID. My point is you have to confirm. If you can spoof your caller ID, then simply forward your calls from the existing carrier to the temporary DIDs provided by your SIP carrier.

One can spoof with flowroute and they only charge about $2 a month per line and .01 per minute.
