How to disable SIP/ALG on Hitron CGN3

I have read several threads on this forum where VOIP does not work with a Hitron CGN3. A solution given involves having SIP/ALG disabled but it is stated that Rogers needs to be contacted to perform this. There are threads that state such assistance would be fee-based and threads that indicate Community experts can help. I have yet to find a thread which states exactly what the 'fix' is. Is this a firmware upgrade?

 

Regardless, I need to have this disabled as well as placing the ip of the telephone adatper in DMZ is not a secure option. I do not believe I should have to pay for such a service and would perform it myself if I knew what the 'fix' actually was.

 

Any help greatly appreciated. Thanks.

Re: How to disable SIP/ALG on Hitron CGN3

I have read the referenced 'Ask an Expert' discussion. Was looking looking for more info as per my questioning on what exactly is the nature of the solution to disable SIP/ALG. The response here is ... 'pay Rogers 69.99 + tax' ... I already pay Rogers 400 per month for other services so not intersted in paying more. This switch setting that only Rogers can disable seems like another way for them to take even more money from me.

Re: How to disable SIP/ALG on Hitron CGN3

Send a pm to @CommunityHelps to turn off the SIP/ALG on the modem.  When that is done, and your phone works, log into the modem, navigate to ADMIN... BACKUP.  Run the Backup Function and store the file on your pc somewhere that you will know where it is.  If the modem loses power, and reboots, or you have to run a factory reset at any time, return to that BACKUP page and run the RESTORE function, using the file that you had previously created.  Reboot the modem and you are back where you left off.

 

The Hitron modems have been seen to lose the SIP/ALG setting, so you end up paying Techexpert again, or, run the backup file.  For 69.99 + tax, you're one third to halfway of the way towards buying a decent router where you have access to all of the settings.

Re: How to disable SIP/ALG on Hitron CGN3

Thanks for the reply and details.

 

Unfortunately CommunityHelps will not assist with this ...This is something Rogers wants to make more money at ... I will take my business elsewhere.

 

I was advised they do not support VOIP services and are unable to disable the SIP/ALG on your Hitron modem.

 

We must contact Rogers TechXpert here: http://bit.ly/TXpert or via 1-866-876-8772

grrrr, yup.   Either take your business elsewhere or bite the bullet and buy a good router.

Re: How to disable SIP/ALG on Hitron CGN3

I found the final reply in that thread from the Rogers Product Manager to be particularly galling.  If the CGN3 router and its firmware had not been designed with the intention to facilitate VoIP and other SIP traffic, it would not be reasonable to expect such features to be added.  But the SIP application level gateway is part of the firmware precisely to enable SIP traffic to overcome NAT issues and reach the target device.  The problem is that SIP ALGs will sometimes work at cross-purposes with client- and server-side solutions and render communication impossible.  That isn't a "our product was not designed to work with external services" problem, that's a "we made our product defective by impairing functionality when trying to improve it" problem.

 

No one is expecting the SIP ALG to be rewritten to address every possible permutation that could break SIP, but it is beyond infuriating that Rogers should be so stubborn in refusing to disable it for those who would benefit.  The entire history of this issue is of a continuous and dogged refusal by Rogers to accept any responsibility when its products fail to perform as designed.  Instead, we get a litany of "open more ports, make your network more visible, put the device in the DMZ."  We got the same "not our problem" attitude when Rogers One Number had similar issues, without the excuse that it wasn't their product, 

 

No, we should not have to expose our devices to reckless risks because Rogers tech staff don't want to click their mouse to clear a tick from a box.

Re: How to disable SIP/ALG on Hitron CGN3

This is an ongoing problem which could be solved very easily by setting the default value for the SIP/ALG to "Disabled".  That would resolve the issue for a vast majority of people.

Re: How to disable SIP/ALG on Hitron CGN3

That's just it, though, are the vast majority of people using VoIP or other services enabled by SIP experiencing problems, and how many people would be adversely affected by losing the functions of the ALG if it was disabled by default?  In my case, I initially had a one-way audio problem with Rogers One Number with toll-free area codes only; all other calls were fine and even that resolved itself within a few months (firmware revision, I expect).  I do audio and video conferencing on several platforms and never had a problem.  Many routers have the ALG enabled by default; there was presumably a reason for that, and perhaps that should be revisited.  But most routers allow it to be disabled by the user; I have no clue why HItron thought otherwise, and unless and until that changes Rogers should disable it for any customer having problems because of it.

Re: How to disable SIP/ALG on Hitron CGN3

If I were a cynical person, I might wonder if Rogers wants it to be difficult and/or costly to disable the SIP ALG, which is now preventing their customers from using competing services.
