We run 8 analog DECT phones in a retail environment  and I am planning to install FreePBX  to replace our 18 year old Panasonic system. I don't really want to replace the cordless phones as they're working fine and are mostly in pretty good condition. 

 

I'm thinking a Cisco SPA8000 will connect the 8 base stations and do the job. Our requirements are pretty simple... 3 lines, 10 extensions (8 cordless, 2 wired - will use Yealink IP phone), see the CLID, transfer and park calls. 

 

Is the SPA8000 a good option for the Cordless analogs? Is there anything else I should consider? I've considered the Panasonic KX-TGP600 but seems overkill with working handsets. Perhaps something we will migrate to as needed.

 

Secondly...

 

Is there anything 'wrong' having FreePBX register 3 trunks as normal phones with 2Talk as Inbound Trunks? Is it considered secure if I enable SIP through the firewall (ASA5505) permitting traffic from only the 2Talk servers? I've heard the horror stories and am cautious about doing so.

SPA8000's are a good device. Being EOL they're also a great price - I picked up about 20 of them last year from Australia that were all brand new for just under $100 each.

 

Depending on how you've got your ASA configured you potentially don't need to do anything. SIP registrations will keep the NAT pinhole open unless you've got super strict rules in place.

Awesome, thanks. To confirm were those SPA’s the Cisco or Linksys model?

Regarding the trunks are there any significant disadvantages using a Sip registration (inbound trunk as 2talk call it) over Sip peering? Am I right in thinking the Sip registration is easier and more secure albeit not as bandwidth efficient?

Cisco and Linksys are one and the same.

 

It doesn't matter if you use SIP registration or peering the bandwidth requirements are identical. There are advantages and disadvantages to both solutions.

@sbiddle, do you know if your AU source has any more available? I can't find anything for less than $300 in this region. There are some used models on Ebay for ~USD60 but new would be better. Not sure if there are any regional differences for this model?

Pretty sure this is the guy they all came from, prices are a little higher now https://www.ebay.com.au/itm/New-Cisco-SPA8000-G4-8-Port-SIP-VoIP-Telephony-Gateway-6MthWty-TaxInv/272758932709
