VOIP

[sukpmp]

Hi, does anybody know if port 5060 is blocked for UDP use? I want to use VOIP.

Starlink uses CGNAT - Carrier Grade Network Address Translation that can make it challenging to open public ports. This is, in part, because the IP address assigned to residential Starlink customers is dynamic. Starlink Business -- which is more expensive (by 5X) -- provides static IP addresses which I understand eliminates this restriction.

VOIP ISSUE - NO SPEECH

 

We have been experiencing issues with Voip since the weekend starting Monday 8/4/24.

Our Voip provider (Vonex) has been working very well until this time.

There was a power outage over the weekend which may have triggered this.

2 other customers in our area who interestingly are also on Starlink with Vonex phones in the same area are also experiencing the same issue.

They also expereienced the power outage.

The issue isnt with registration but with NO SPEECH in either direction on most calls, but not all.

 

What has Starlink done?

Given that all 3 customers are exeriencing this it is a Starlink issue.

Vonex report that they have a sudden increase in other customers on Starlink who also report this issue.

If it happens after a power cycle of the Starlink equipment, then its fair to say that the issue wil only get worse as more sites inevitably reboot their equipment.

 

I can't see why CGnat is the issue because it has been working OK for months, maybe a year.

Have Starlink enabled SIP-ALG ?

Can it be checked if its on and then turned off? How?

 

Does anyone have any thoughts on thus issue.

 

We have had to resort to a 4G backup just for the phones.

Excellent questions. Probably best directed to Starlink Support.
