"Problem Solving" call drops in a timeframe?

Usually calls that drop like in a time frame EXAMPLE every 2minutes are known and common and easy to fix,this is most likely related to your modem/router.
When your in a Live call your Voip call is constantly sending/receiving packets to and from Fongo server and when the modem/router is set in security mode within a time frame it will automatically cut off certain ports for security and this will then drop your Live Voip calls.
1. First suggestion is to check inside the modem/router for a setting "keep alive" - Enable this, it's basically telling the devices connected to the modem/router that there still here and alive and not to worry.
2. Second suggestion you might have to upgrade the modem/router firmware.
3. Third suggestion is to reduce the firewalls to minimum in the modem/router. (not recommended)
4. Fourth suggestion check your modem/router for a SIP ALG setting - Disable this.
Update:
5. If the above 4 is still not working for you then an alternative way is to try and upgrade from a 3rd party site earthier called Tomato or DD-WRT firmware.
I hope I have covered everything related to dropped calls.
Good luck!
