We use H.248 in our CLEC area. The voice service for that ONT runs on a specified VLAN for that ONT, so if we had to share our infrastructure with other CLECs we could do that.

An incumbent in Canada has revealed that its voice service on FTTP deployments is based on H.248 MEGACO (Media Gateway Controller). Are there any examples of CLEC access to such FTTP deployments ? (for instance, an area where the copper was removed, leaving only fibre to homes, do CLECs retain competitive access via fibre to homes, or is it going out of business or going with pure SIP/VoIP over the regular internet connection, instead of using the "quality" voice link in the GPON with garanteed bandwidth ? Can this protocol support the programming of one OLT/MG connecting to the Telco's MGC, while the OLT/MG next door connects to the CLEC's MGC ? Or does the protocol result in MG's "discovering" the nearest MGC and connecting to it (making it hard to have multiple MGCs from competing telcos). I have been lead to believe that most OLTs came with a SIP based ATA. It appears that H.248 is more telco friendly and scales better. Does this mean that H.248 is more widely deployed in FTTH ?
