Disable sip alg

How can I disable SIP ALG on my rented modem router from Xfinity? I've called tech support and was told to trade in my modem for a newer version. There are no settings in the 10.0.0.1 website or the Xfinity app. My modem is not that old, maybe 2-3 years at best. Can anyone help?

AFAIK, it can't be disabled.

@user_f9fdwg - oneway to deal with the SIP ALG option is to configure Xfinity provided Gateway into the Bridge Mode,

and get your own Router that has SIP ALG as an available and configurable feature. (KB from Netgear)

There are at least 3 ways to fix this.  Finding any xfinity tech that knows this in tier1 support may be impossible as far as I can tell.

Their tier 1 will tell you that they're "Advanced Technical Support".  They are NOT.  Them saying this is rediculous and its insulting to hear it. ugh

example on the XB8-T modem/router combo

  1. You could set their modem/router to bridge mode and use your own router.  Then set your router to disable SIP/ALG.
  2. You could access their modem/router menu > firewall settings > set security to LOW  (SIP ALG is a hidden feature that gets turned on automatically under other levels of security)
  3. You could also access advanced security and flag your phone/device as an IP phone.

Can you show menu selections in the XB8 modem 10.0.0.1 page for option 3)?  I don't see an advanced security page for Firewall security other than IPV6 and IPV4 which either selects the security level or custom level Firewall>ipv4>security level> high, medium,low custom.

There is an Advance menu that shows port forwarding,port triggering, DMZ , and Device Discovery

I have connected my ATA and it is shown as a connected device same as  all other devices.

I cant confirm the 3rd option myself since this wasnt my chosen method.

I have tested the other to methods and confirmed it works.

However, if you go to the xfinity app > choose wifi > devices > find your phone device > choose device details > Device Type (Set this to Phone).
