Cisco vs Avaya IP Phones: Which Is Right for Your Canadian Business?
When Canadian businesses need to upgrade or replace their phone system, the two names that come up most often are Cisco and Avaya. Both brands are trusted worldwide, but they serve different needs. This guide breaks down the real differences so you can make the right call — without overspending.
Who Makes Each Phone?
Cisco is the world's largest networking company. Their IP phones (7800, 8800 series) are built for businesses that already run Cisco infrastructure — routers, switches, Unified Communications Manager (CUCM).
Avaya was born from Lucent Technologies and has been a staple in North American call centers and enterprise environments for decades. Their phones (1400, 1600, 9600 series) integrate tightly with Avaya Aura and IP Office systems.
Protocol: SIP vs Proprietary
This is the most important factor most buyers overlook.
- Cisco phones support both SIP (open standard) and SCCP (Cisco's proprietary protocol). If you run a non-Cisco PBX, choose SIP-compatible models.
- Avaya phones use H.323 or SIP, depending on the model and system version. Older Avaya digital phones only work with Avaya systems.
Bottom line: If you're on a mixed or cloud VoIP system, SIP-compatible models from either brand will work. If you're on a legacy proprietary system, stick with the matching brand.
Price Comparison (Canada, 2026)
| Model | New (CAD) | Refurbished (CAD) |
|---|---|---|
| Cisco 7841 | ~$280 | ~$95–$130 |
| Cisco 8851 | ~$420 | ~$160–$200 |
| Avaya 9608G | ~$320 | ~$80–$120 |
| Avaya 1416 | ~$240 | ~$60–$90 |
Refurbished units from a certified Canadian supplier like Telecom Depot Direct include a 12-month warranty and ship within 1–2 business days from Montreal — no customs, no brokerage fees.
Which Should You Choose?
Choose Cisco if:
- You already run Cisco networking equipment
- You use Cisco Unified Communications Manager (CUCM)
- You need advanced video or collaboration features (8800 series)
Choose Avaya if:
- You're on Avaya Aura, IP Office, or a legacy Nortel/Avaya PBX
- You're replacing end-of-life Avaya digital phones
- You want cost-effective handsets for a large call center deployment
Can You Mix Both Brands?
Yes — if your system runs SIP. Cloud-based VoIP platforms (RingCentral, 8x8, Teams Direct Routing) support SIP phones from any brand. Proprietary PBX systems do not.
Final Recommendation
For most Canadian SMBs upgrading from a legacy system: refurbished Avaya 9600 series phones offer the best value with full compatibility and proven reliability. For businesses building a new Cisco-based infrastructure: the Cisco 7841 hits the sweet spot of features and price.
