SIP ALG

Hello everyone

I have an IB and I use the iPhone app from Peoplefone over WLAN (calling via SIP).

Unfortunately, since I’ve had the IB, the conversations I have on Peoplefone are always interrupted.

After an inquiry with Peoplefone support, I found out that the SIP ALG had to be deactivated on the Swisscom router.

In the GUI of the IB I can’t find any security or firewall menu where you could activate/deactivate the SIP ALG function.

Do you know where you can configure the SIP ALG parameter in the Swisscom IB?

Greetings

I use two non-Swisscom SIP providers and have no problems with interruptions.

I didn’t even have to configure anything at the IB so that SIP works.

There is also no way to set something like that like ALG.

I haven’t seen any menu on the IB that says you can switch SIP ALG on or off. But are you sure that your WLAN is very stable and suitable for VoIP. The problem most likely lies in this area.

Hello everyone

After calling the hotline, I was recommended to give the IB’s 2 WLANs (2.4 and 5 GHz) different SSIDs, because otherwise the devices would jump from one frequency to the other and that could lead to instability of the connection.

After I made this change, I no longer notice any interruptions.

Problem solved thanks to the good support of the Swisscom hotline

Bye
