Adding additional FX0 ports on uc540 via gateways

[raymond-sue]

Hi,

Our sales rep has sold a UC540W-BRI-K9 to a customer but the customer doesn't have any BRI connections, they use PSTN lines.

The issue is that they have 7 PSTN lines. We can purchase a 4 port FXO interface card but it's not enough to connect all the PSTN lines because the UC540 has only one expansion port..

I guess the only option is to purchase a gateway device to allow the additional FXO.

My question is, which media Gateway is supported on the UC540 via CCA programming?

I know that SPA8800 is supported on the UC540 with the new software pack but it's only for the FXS ports.

Are there any other devices?

Regards

Raymond

Where are you lcoated? The best choice would be have teclo to conver analog line to BRI ?

That will give them better call quality and many features.

Other than that for FXO you have buy a small cisco router and configure it somehow.

I'm located in Australia. Converting analog to BRI is not a good choice for us because the customer will pay higher call rates.

I guess the easiest way out is to replace the UC540W-BRI-K9 with a UC540W-FXO-K9 and order the additional 4 port FXO interface card.

Or you can switch to a SIP ITSP and stop paying telco altogether.

Hi,

     I am looking for possible solutions for adding an additional FXO line to a UC540 as well.  Mine already has the additional VIC2-4FXO module and all FXO ports are used.  From reading the Manuals, Release Notes, and Forums, it sounds like the 8800 will only support additional FXS ports.  I have not found a solid answer as to why that is.  It seems like it would be a hardware/platform overload issue for the UC540 to support more than 8 FXO lines.  Is this assumption accurate or is there something we can do about it?
