YES

Best to disable load balancing and also SIP helper. Most have ALG enabled by default, which is usually fine for Cisco but worth noting that not across all versions of firmware. Recommend increasing MTU size to 1500. Increase UDP port timeout to 600 seconds.

RVS4000

NO

One way audio after doing attended transfers. Recommend replacing.

WRT100, WRT110N, WRT120N, WRT150N, WRT160N, WRT300N, WRT320N, WRT350N, WRT54G, WRT55AG, WRV200, WRV210, WRV54G, WRT610, LRT224

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

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.
