Recommended Consumer Routers
Router Make | Router Model | SIP ALG Setting Location (Relative, May Vary with Firmware Version) |
---|---|---|
Linksys | WRT1900ac | Settings->Administration tab->uncheck SIP ALG under Application Layer Gateway |
D-Link | DIR-868L | Advanced Settings->Firewall Settings->uncheck SIP (ALG) |
Asus | RT-AC66 or better* (68u, 87u, 88u, AC3200, GT-AC5300) | Advanced WAN->NAT Pass Through->SIP Pass Through->Set to Disable |
Netgear | R7000 or better (R8000, R8500) | Advanced->WAN Setup->toggle Disable SIP ALG |
Cisco | EA6500 or better (EA6900, etc.) | Router Settings->Connectivity->Administration tab->uncheck SIP ALG |
Trendnet | TEW812 or better | Advanced->Firewall->ALG->toggle SIP |
*Asus router models may vary as listed. The RT-AC68u is also sometimes listed simply as an AC1900, which is a designation of its operating frequencies (802.11ac) and maximum rate (1900, 3200, etc.). This does not apply strictly to Asus routers - if a router is simply listed as "AC3200" or similar, that is not the product model.
Known Incompatible or Problematic Consumer Routers
If your home router is not listed as compatible or known incompatible and you cannot locate a setting related to SIP ALG, first attempt to update the router firmware to the latest available, and recheck the router settings - some manufacturers may not have exposed the setting until later firmware versions. Some routers may include SIP ALG, but not exposed through the web interface normally accessed to change settings. Such routers may require use of a telnet connection, which is highly uncommon for residential consumer routers.
Router Make | Router Model | Incompatibility Rationale/Problems |
---|---|---|
TP-Link | C7/C9 Archer (AC1750/AC1900, respectively) | No exposed SIP ALG toggling option in web interface |
Apple | A1354 (4th Gen Airport Extreme) | No exposed SIP ALG setting, spottiness with handset stability |
Apple | A1408 (5th Gen Airport Extreme) | No exposed SIP ALG setting, spottiness with handset stability |
Apple | A1521 (6th Gen Airport Extreme) | No exposed SIP ALG setting, spottiness with handset stability |
Manufacturer Specific Notes
Apple
In comparison to other manufacturers implementations and options for configuration, the Airport Extremes strip configuration down to a few valid combinations - generally enabling or disabling NAT on the router with no ALGs exposed.
