Review: be patient, make sure you know what your are doing. - works great ! lotsa good instructions to help you get going !!! I came from CISCO UCM so the was manageable. Review: Look and work great. Love it. - Installed six of these in my house. They work and look great. The only negatives are I had to have them professionally installed and you had to be adjacent to an outlet or Cat 6 wall connection to a server area. Otherwise, unsightly wires would hang down the wall. I was lucky as it was new construction and the wires were installed in advance. ## Features - Supports up to 3000 users and up to 450 concurrent calls - Zero configuration provisioning of Grandstream SIP endpoints - Built-in conferencing & meetings platform; supports desktop, Wave app, and SIP endpoints - Wave for Android, iOS, Chrome and Firefox browsers allows communication with all UCM6300 users & solutions - API available for third-party integrations, including CRM and PMS platforms - Advanced security protection with secure boot, unique certificate and random default password to protect calls and accounts - Three Gigabit auto-sensing RJ45 network ports with integrated PoE+ and support NAT router - Automated NAT firewall traversal service facilitates secure remote connections - Supports Full-Band Opus voice codec and H.264/H.263/ H.263+/H.265/VP8 video codec, jitter resilience up to 50% packet loss - Compatible with GDMS for cloud setup, management and monitoring ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08NFJGSS9 | | Batteries | 1 Unknown batteries required. | | Best Sellers Rank | #108,187 in Office Products ( See Top 100 in Office Products ) #3 in PBX Phones & Systems | | Customer Reviews | 4.4 4.4 out of 5 stars (80) | | Date First Available | January 1, 2021 | | Is Discontinued By Manufacturer | No | | Item Weight | 1.32 pounds | | Item model number | GS-UCM6301 | | Language | English | | Manufacturer | Grandstream | | National Stock Number | 0 | | Product Dimensions | 10.63 x 6.89 x 1.42 inches | ## Images ![UCM6301 IP PBX | 1 FXO Port, 1 FXS Port | Desktop/Wall-Mount - Image 1](https://m.media-amazon.com/images/I/41k3KmYhhyL.jpg) ## Questions & Answers **Q: Hi, can this be used in Singapore?** A: Yes **Q: Can I use a sim card in this model** A: This model does not support the use of a SIM card.

We’re a 100% remote business and we’re constantly chasing issues with VPN connecting back to our phone system. The Remote Connect is amazing and just works no matter what kind of network you’re on and gets right through CGNAT, double NAT, etc. ## Frequently Bought Together - Grandstream UCM6301 IP PBX | 1 FXO Port, 1 FXS Port | Desktop/Wall-Mount - Grandstream GXP2170 IP Phone | 12 Lines, 6 SIP Accounts | 4.3-Inch Color Display | Dual-Port Gigabit Ethernet with Integrated PoE - Grandstream GXP2135 IP Phone | 8 Lines, 4 SIP Accounts | 2.8-Inch Color Display | Dual-Port Gigabit Ethernet with Integrated PoE --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/354081156-ucm6301-ip-pbx-1-fxo-port-1-fxs-port-desktop](https://www.desertcart.hr/products/354081156-ucm6301-ip-pbx-1-fxo-port-1-fxs-port-desktop) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-23*
