Meraki
Model	Compatibility	Notes
MX64, MX84	YES	Some providers offer configuration files to optimize settings for VoIP.
Mikrotik
Model	Compatibility	Notes
All	YES	Mikrotik SIP ALG should be disabled. Mikrotik has a forum on how to do this for their routers.
Motorola
Model	Compatibility	Notes
NVG510, NVG589, 3360, 2210	NO	No way to disable ALG (contact provider if need this as may be way to do it using Telnet but depends on ISP i.e. set ip alg sip-enable off). This causes calls to drop. Passthrough required to compatible router or replace.
NVG595	YES	Turn off SIP ALG (Firewall > Firewall Advanced). Add google DNS servers (8.8.8.8 and 8.8.4.4) if using Polycom. May need to get ISP to add this for you.
SBG6580	YES	Disable ALG and ensure firmware is 3.3 or newer. Still some reports of issues but newer firmware should help.
Netopia 2000, Netopia 3000	YES	Disable ALG. Disable DNS proxy if using Polycom phones. Make sure firewall set to ClearSailing or lower, otherwise expect registration issues. Can use PuTTY to access SIP settings (e.g. set ip sip-passthrough off).
Netgear
Model	Compatibility	Notes
R6100, R6200, R6220, R6250, R6400	YES	Latest firmware needed plus disable ALG and DoS (Denial of Service) settings.
R6300 v1, WGR614 v8 and above, WNDR3400, WNDR3700 v1/v3/v4, WNR3500L v1 and above, WNDR3300, WNR1000 v2 and above, WNR2000 v2 and above, DG834G, AC1750, FVS336G	YES	Disable Netgear SIP ALG and DoS settings. Some providers offer configuration information. May need latest firmware to access ALG.
R7000 Nighthawk, R8500 Nighthawk X8	YES	Disable SIP ALG and DoS settings. Also do not setup QoS. May still have some audio related issues or registration failures.
AC1450, RP114, FVS Series, JNR Series, JWNR Series, R4500, R6050, R6700, R6900, R7000, R7500 Nighthawk X4, R7900 Nighthawk X6, SRX/UTM (all models), WGT624, WNDR3400, WNDR3700 v2, WNDR3800, WNDR4000, WNDR4300, WNDR4500, WNDR4700, WNDR4720, WNR1000 v1, WNR2000 v1, WNR2500, WNR3500, WNR834B, WPN824, MR814, FVS318, FVG318	NO	Dropped calls and poor audio. Try updating firmware to see if ALG setting becomes available. Otherwise, replace.
7550	YES	Disable ALG and DoS. DMZ mode if still issues.
C3000, C3700, C6300, C7000, WCOM, CG814WG/T, CGD24G	NO	Audio problems and also dropped calls. Replace.
CG3000 (Comcast!)	NO	Problems even when in DMZ or bridged mode. Note that Comcast often brands this device and gives you no access to SIP ALG (some forums suggest Comcast SIP ALG can be disabled if you call them). Many problems reported with this device. Recommend replacing. Get a Motorola Surfboard modem (e.g. SB6141) and use your own router. Can then remove the Comcast rental fee for the modem. Will likely pay for itself within 6 months. I can personally attest to issues with CG3000 and spent way too many hours troubleshooting.
CGD24G	NO	Issues. Recommend pass-through to compatible router.
Netopia
Model	Compatibility	Notes
3000	YES	Disable ALG.
Optimum
Model	Compatibility	Notes
Cloud devices	NO	DMZ mode and likely need ISP help to do this.
Pace
Model	Compatibility	Notes
PLC 3801HGV, PLC 5031NV, PLC 5168NV-110	NO	Disable attack detection and put into pass-through mode to better router. Consider adding custom service to all SIP traffic through on ports 5060 through 5080. Many models give no access to SIP ALG so unable to disable. Some phones will have registration issues (e.g. Polycom) due to the inability to add DNS servers. Bridge mode is not effective so even doing this and using another router will not guarantee success. Also recommend editing UDP session timeout to something higher (e.g. 600 seconds).
Quantum
Model	Compatibility	Notes
Q1100, G1100	NO	Dropped calls. Also Busy Lamp Field (BLF) issues. Recommend DMZ to other router. No way to disable ALG.
Rosewill
Model	Compatibility	Notes
RNX-AC750RT	YES	Disable ALG. Some providers have configuration files for this router.
Satellite Equipment
Model	Compatibility	Notes
All	NO	Latencies are very high for satellite service since they are in geo-sync orbit 22,000 miles up. VoIP does not work well with satellite Internet service.
Siemens
Model	Compatibility	Notes
SpeedStream 4200	YES	Disable ALG.
SpeedStream 5100	NO	Audio problems. DMZ or bridge to better router.
Sagecom
Model	Compatibility	Notes
All	NO	Drops calls and audio artifacts. Replace or DMZ to another router.
Samsung
Model	Compatibility	Notes
Ubigate	YES	Disable ALG but need Internet provider assistance to do this.
SMC
Model	Compatibility	Notes
SMC 3100, SMC D3GNV	NO	Audio problems. DMZ to better router.
SMC 8014, SMC D3G-CCR	YES	Typically can be made to work. Disable Smart packet detection (SPI firewall).
Sonicwall
Model	Compatibility	Notes
All	YES	Generally, you will have good success with Sonicwall, especially the newer models (SonicOS Enhanced). Upgrade to latest, stable firmware. Disable ALG (called SIP Transformations). Enable consistent NAT. Create access rules if necessary.
Technicolor
Model	Compatibility	Notes
TC8305C, TC8715	NO	Firewall should be changed to the low setting which may help. No way to disable ALG. Best to replace.
Thompson
Model	Compatibility	Notes

Model	Compatibility	Notes
Most models	NO	Replace. Audio problems.
Archer C3200, Archer C9 AC1900, SafeStream TL-600VPN, TL-WR1043ND v2	YES	Disable ALG, if applicable. Some providers have configuration files on offer for these routers. Disable DNS Proxy/Relay.
TrendNet
Model	Compatibility	Notes
TEW-639GR, TEW-711BR, TEW-731BR, TW100	NO	Replace. Audio problems due to ALG. No way to disable.
Ubee
Model	Compatibility	Notes
DDW3610, DBW3611	NO	Depends on firmware version. Many do not allow you to turn SIP ALG on or off.
Ubiquiti
Model	Compatibility	Notes
Edgemax Edgerouter, Air router HP	YES	Must disable ALG (Network tab then uncheck NAT protocol). For Edgerouter need to use the CLI (configure then set system conntrack modules sip disable and then save and then exit.
Vizio
Model	Compatibility	Notes
XWR100	NO	Unstable software firewall. Try newer firmware. May need to replace.
Watchguard
Model	Compatibility	Notes
XTM Series	YES	No issues if using port 5060 for SIP control traffic. Increase UDP timeout to 600 seconds.
X-edge E series	YES	No issues if using port 5060 for SIP control traffic. ALG disabled by default. Increase UDP timeout to 600 seconds.
Westell
Model	Compatibility	Notes
6100, 7500, 9100 (Verizon)	NO	Disable ALG (Advanced > ALG > uncheck SIP). Disable software firewall but still issues. The keep alive packets would have to be around 5 seconds for this to work and keep pin hole open. However it does not maintain this after re-boot. Suggest replacing.
Western Digital
Model	Compatibility	Notes
MyNet N600	YES	Disable SIP ALG.
Zhone
Model	Compatibility	Notes

 Certain firmware version can cause problems with dropping audio. Disable ALG (Telnet required for this on some firmware versions i.e. enable Telnet and then nvram set nf_sip=0 and then nvram commit and power cycle). Check Advanced Settings > WAN > NAT Passthrough > SIP Passthrough and verify disabled.

 No way to disable ALG (contact provider if need this as may be way to do it using Telnet but depends on ISP i.e. set ip alg sip-enable off). This causes calls to drop. Passthrough required to compatible router or replace.

 Problems even when in DMZ or bridged mode. Note that Comcast often brands this device and gives you no access to SIP ALG (some forums suggest Comcast SIP ALG can be disabled if you call them). Many problems reported with this device. Recommend replacing. Get a Motorola Surfboard modem (e.g. SB6141) and use your own router. Can then remove the Comcast rental fee for the modem. Will likely pay for itself within 6 months. I can personally attest to issues with CG3000 and spent way too many hours troubleshooting.

 Disable attack detection and put into pass-through mode to better router. Consider adding custom service to all SIP traffic through on ports 5060 through 5080. Many models give no access to SIP ALG so unable to disable. Some phones will have registration issues (e.g. Polycom) due to the inability to add DNS servers. Bridge mode is not effective so even doing this and using another router will not guarantee success. Also recommend editing UDP session timeout to something higher (e.g. 600 seconds).

 Disable ALG (Advanced > ALG > uncheck SIP). Disable software firewall but still issues. The keep alive packets would have to be around 5 seconds for this to work and keep pin hole open. However it does not maintain this after re-boot. Suggest replacing.
