Frequently Asked Questions What Changed With Poly, and Why Your Dispatch Center Needs To Act Now?
Poly has stopped manufacturing its specialty dispatch communications equipment. Critical components for several legacy products are no longer available, which means organizations still relying on Poly dispatch headsets, PTT cables, and amplifiers face a growing list of operational problems: dwindling spare parts, zero manufacturer repair paths, and rising downtime risk during the moments that count most.
For PSAP and 911 dispatch centers, air traffic control facilities, utility command centers, and healthcare communication hubs, this creates real urgency. When a Poly CA22CD fails at 2 a.m. during a multi-agency emergency, there is no replacement sitting on Poly’s shelf. When your SHS 1890-15 PTT amplifier cable wears out after years of 24/7 use, the product line that built it has gone dark.
We see dispatch center managers dealing with this every week. The Poly headset discontinued replacement question has become one of the most common calls we take at Headsets Direct. The good news: you have a clear path forward.
Fast Answer: What Replaces My Poly Model?

Security and Compliance
SHG products meet the security and procurement standards that government and public safety buyers require. Every SHG headset and accessory is TAA- and NDAA 889-compliant, and all products align with the Department of Defense Memorandum on Collaboration Peripherals. The SHG S D200 goes further with FIPS 140-2 listed 256-bit AES encryption, making it suitable for secure and classified environments. SHG also conducts ongoing penetration testing and hackathons to stay ahead of cybersecurity threats, a step that earned them selection as the U.S. Army’s sole provider for headset endpoints.
Reliability
SHG products maintain a reliability rate exceeding 99.96%, a figure built on nearly four decades of engineering headsets for the Department of Defense, all military branches, and first responders. For a 911 dispatch or air traffic control headset replacement, that kind of track record is nontrivial. A failed headset at a PSAP position during a critical incident can have serious consequences.
Availability
SHG guarantees order fulfillment within 30 days for existing products, and many items ship within one to three business days. We keep SHG inventory in stock at Headsets Direct, so your dispatch center can avoid the backorder limbo that plagues discontinued Poly SKUs.
How To Choose the Right SHG Replacement
Selecting the right Poly headset discontinued replacement comes down to a few straightforward decisions. Here is how we walk our customers through it:
Step 1: Decide on Your PTT Method
Your first decision is whether to use wireless or wired push-to-talk.
Choose the SHG S D200 (wireless DECT) if your operators need cordless freedom to move around the dispatch floor, or if you need encrypted PTT for secure environments. This is your Poly CA22CD alternative.
Choose the SHG S D145-PTT/AMP (wired amplified) or SHG S D145-PTT (wired non-amplified) if your operators stay at fixed consoles and you prefer the simplicity of a hardwired connection. These are your Poly SHS 1890-15 replacement and Poly SHS 1890 replacement options, respectively.
Choose the SHG S D145-PTT Cable if your facility runs 6-wire consoles and users prefer an inline button that triggers the PTT keying of the mic (versus the above option which uses a pistol grip).
Step 2: Select Your Headset Form Factor
For dispatch operations, monaural (single-ear) headsets are the standard because operators need situational awareness. They must hear radio traffic, colleague communication, and room-level activity with the uncovered ear.
The SHG S 300-PL is a solid mid-level option with a foam cushion, ideal for high-volume centers where per-unit cost matters during large fleet purchases.
The SHG S 500-PL is the premium choice, with a leatherette cushion and an included oversized cushion option for operators who prefer greater ear coverage. It connects directly to emergency dispatch base consoles via its PL QD, eliminating the need for a separate cable.
Both connect to the SHG adapters and cables listed above, and both work with legacy Poly amplifiers, like the CA12CD-S and CA22CD, if you have units still in service.
Step 3: Confirm Security and Compliance Requirements
Before placing a purchase order, verify the compliance standards your agency requires:
- TAA compliance is required for most U.S. federal procurement. All SHG products meet this.
- NDAA Section 889 compliance prohibits the use of certain foreign-manufactured telecommunications equipment. All SHG products meet this.
- FIPS 140-2 encryption is required for handling classified or sensitive information. The SHG S D200 is the only adapter in this lineup to carry FIPS 140-2 listing.
- DoD Memorandum on Collaboration Peripherals compliance is increasingly required for military and intelligence-adjacent operations. All SHG products align with this guidance.
Step 4: Pilot, Then Bulk Order with Spares
We always recommend starting with a pilot deployment of five to 10 consoles. Test audio quality, PTT responsiveness, and operator comfort before committing to a fleet-wide rollout. Once you validate the pilot, place your bulk order and include replacement cushions and 3 to 5% spare units so you have a buffer for breakage or new hires.

Rollout Checklist for Enterprise and Agency Deployments
Moving from Poly to SHG across an entire dispatch floor takes coordination. We have helped agencies handle this process smoothly, and here is the deployment sequence we recommend:
- Asset Inventory and Compatibility Audit: Document every Poly model currently in service at each console position. Record serial numbers, cable types (4-wire vs. 6-wire), and console make/model. This inventory becomes your crosswalk to SHG replacements.
- Pilot Consoles: Install SHG replacements at a small group of consoles. Verify audio levels, PTT responsiveness, and headset comfort throughout a full shift. Collect feedback from operators before scaling.
- Operator Training: Build a brief training template covering headset adjustment, PTT button location (index finger vs. thumb for operators transitioning from Poly), and basic care instructions. For the SHG S D200, include DECT pairing procedures and firmware update steps using the D200 App.
- Hygiene and Ear Cushion Rotation Plan: For 24/7 operations running multiple shifts, establish a cushion rotation schedule. Stock replacement foam cushions (S 300-PL) and leatherette cushions (S 500-PL) so operators always have a fresh set. This prevents hygiene issues and extends headset lifespan.
- Spares Strategy: We recommend stocking 3-5% spare units for headsets, cables, and adapters. For a 200-position dispatch center, that means six to 10 spare headsets and a proportional number of spare cables.
Documentation: Label each console position with its SHG model numbers. Create a standard operating procedure (SOP) document that covers DECT pairing steps (if using the D200), cable replacement, and warranty claim procedures.

Frequently Asked Questions
Yes. SHG adapters and cables use the same PJ7 2-prong (dual-prong) console connectors and PL-style Quick Disconnect headset interfaces that Poly used. If your current Poly headset top has a PL QD connector, it will plug directly into any SHG adapter or cable. Similarly, SHG headset tops (S 300-PL, S 500-PL) work with legacy Poly amplifiers like the CA12CD-S and CA22CD if you still have functioning units. SHG specifically engineered these products to drop into existing dispatch infrastructure with no console modifications.
A 6-wire system carries separate transmit and receive audio paths, along with signaling wires, which allows the console to manage radio and telephone audio independently. Most modern PSAP and ATC dispatch consoles use 6-wire connections. A 4-wire system carries basic transmit and receive audio without the extra signaling lines and is typically found in older PBX-based or ACD dispatch setups. If your console has a 6-wire PJ7 jack, you need the SHG S D145 series. If it uses a 4-wire PJ7 jack, you need the SHG S D144-AMP. Installing a 4-wire cable in a 6-wire console (or vice versa) will result in audio problems, so confirming your wire configuration before ordering is essential.
All SHG headsets, cables, and adapters are TAA- and NDAA Section 889-compliant, making them eligible for U.S. federal government procurement and GSA Schedule contracts. The SHG S D200 DECT adapter is also FIPS 140-2 listed with 256-bit AES encryption, which is required for secure communications in classified or sensitive information environments. All SHG products comply with the Department of Defense Memorandum on Collaboration Peripherals for use in secure spaces.
For in-stock SHG products, we typically ship within one to three business days. SHG maintains U.S.-based warehouse inventory and guarantees fulfillment within 30 days on all existing products. If you are planning a large fleet refresh, we recommend contacting our team early so we can confirm stock levels and stage your order for rapid delivery. We have fulfilled multi-hundred-unit dispatch center deployments on compressed timelines, and our account reps will give you a realistic ship date before you commit.
SHG headsets (S 300-PL, S 500-PL) and 6-wire cables/amplifiers (S D145-PTT, S D145-PTT/AMP) carry a 2-year manufacturer’s warranty. The SHG S D200 DECT adapter also carries a 2-year warranty. The SHG S D144-AMP 4-wire cable carries a 2-year manufacturer’s warranty. SHG also offers a 24-hour swap program for warranty claims, so your operators never have to wait weeks for a replacement.
