Hi, I have a FreePBX system that I use PRI for voice line, I’m looking to add 40 analog extensions to it and was wondering what would be a good ATA/FXS device to use for this purpose?
Thanks

Channel Banks work great for this. As an alternative, we actually like Adtran 924e’s - you can get them on EBAY fairly cheaply and they work great - we have a Hotel that has 90 rooms and we are using 3 of them - they are awesome.
I will second the Adtran recommendation and add Grandstream GXW4248. These will provide 48 FXS ports. Had good luck in Hotel environment with these as well.
Thank for your inputs guys, does it matter if my PBX is using SIP or PRI?
Not really.
Not at all - the only thing you will lose with a PRI is T.38 - but the number of SIP providers that actually has a fully-baked T.38 infrastructure is very small - so no, PRI with either a Channel Bank or an FXS gateway works great.
