CMER TUNNEL V1.2 & OPTIMA SAVER

Carry G.729a voice calls on 8.1 kbps instead of 42 kbps.

Strip repetitive 40-byte IP+UDP+RTP headers, multiplex up to 256 concurrent calls into one encrypted stream, and traverse CGNAT or LTE firewalls with zero port forwarding.

Turn a 2.8x oversubscribed branch circuit into 54% clean utilisation.

100 CONCURRENT CALLS ON A 1.50 MBPS LINK 3.39 Mbps reclaimed

4.20 Mbps congested RTP -> 0.81 Mbps clean CMER stream.

Without CMER, 100 G.729a calls demand 4.20 Mbps—saturating a 1.50 Mbps branch circuit 2.8x over. A $40 Cloud Router bundles all 100 calls into 0.81 Mbps, leaving 0.69 Mbps (46%) clean headroom.

Select SX, TX, or UX outbound encrypted profiles per site to balance peak compression, strict firewall traversal, and jitter resilience.

ZERO-NAT EDGE BRIDGE OPTIONS

Three ways to deploy CMER v1.2 at customer branches.

Comparison of Cloud Router, Cloud Pi, and Cloud PC Zero-NAT edge bridges
Bridge Form Factor Hardware / Media Tunnel Modes NAT Traversal Ideal Deployment
Cloud Router ($40) Pre-flashed compact router firmware ($40 hardware) SX / TX / UX outbound encrypted UDP Zero-NAT (CGNAT & LTE/5G safe) Fixed retail offices, remote call centres, branch PBXs

CMER TUNNEL FAQ

Compression and Zero-NAT questions.

Does 8.1 kbps compression degrade audio quality?

No. CMER strips duplicate network headers rather than re-encoding audio—your G.729a voice frames arrive bit-intact.

What are SX, TX, and UX modes?

Selectable outbound transport profiles inside CMER v1.2 tuned for maximum compression, strict firewall traversal, or lossy wireless links.

Do customer offices need static public IPs?

No. Outbound encrypted sessions work cleanly behind dynamic IPs, LTE/5G modems, and carrier-grade NAT.

Does CMER pair with Cloudfonica voice switches?

Yes. CMER terminates natively across all 7 Cloudfonica global hubs as well as private licensed instances.
