Anyone have a tool that a technician or customer could put on a computer on a customer's network, and it will tell them if a SIP ALG was disabled or enabled?

Colton ? if Jive View doesn?t work out for you or if you?re just looking to compare/contrast with other commercially available products ? our DVQattest platform addresses these technical issues (and then some).

Anthony, I attempted to contact you directly about your products, but your server said: The response from the remote server was: 554 5.7.1 Mail appears to be unsolicited -- send error reports to postmaster at telchemy.com I was trying to get pricing and see if it can fit our needs/budget.

Some of this tool's functions are indeed exposed to the public. Anyone can use this to check their network's VoIP-readiness (including presence of a SIP ALG) and the quality of their connection to the Jive platform.
Is it based on opensource software, or what?
100% home-grown. -- Simon Perreault Director of Engineering, Platform | Jive Communications, Inc. https://jive.com | +1 418 478 0989 ext. 1241 | sperreault at jive.com
In my experience, mainly Polycom and Adtran, most SIP devices send packets with a source port 5060. SIP ALG preserves the source port but regular NAT changes the source port (maybe not for the first device) just like NAT for any other service. On 07/18/2017 10:00 AM, Colton Conor wrote:

We started deploying some Ubiquiti Unifi USG routers, and discovered that they had SIP ALG enabled by default.
Typically we just put the Polycom VVX phones to register with TCP for signaling, and this bypasses most SIP ALGs as I think most can only handle SIP using UDP and not TCP right?
Well I guess the SIP ALG used in the Ubiquiti Unifi USG does modify even SIP using TCP. I know Ubiquiti Unifi USG use a fork of the vyatta operating system, and the command to disabled it is set system conntrack modules sip disable
We were able to turn SIP ALG off, and now everything is working fine.
Would be great if there was a tool a low level tech or customer could use to test the network?

quite a while ago SIP ALG Detector was announced, an oss client-server pair for detecting SIP ALGs written in ruby: - https://lists.kamailio.org/pipermail/sr-users/2009-June/023630.html But that link was no longer available when I checked earlier today, so I asked the developer about it and he made it available on github: - https://github.com/ibc/sip-alg-detector As noted in its readme, it is not really maintained, but it may still work or eventually can be something easy to fix for someone that looks for an OSS SIP ALG detector.
