Hi Guys,
I have a customer who is experiencing call qulaity issues over a SIP providor including Echo. Internal calls are all OK.
The 3CX has 2 networkcards running V7.1 and Win XP Pro with all AV and Firewalls turned off.. The first network card is on the private Internal LAN with the rest of the Snom phones, PC's, Servers etc.
The second network card is on a seperate subnet connected to a Cisco router provided by the SIP providor which is meant to be a quality assurance broadband line.
I have only ever seen a maximum of 3 external calls going through the system and the line is assured upto 8 concurrent.
We have tried G711 and G729 and still get issues.
I have logged calls with the SIP providor with not much outcome so wondered if you guys could add anything extra?
Regards
Steve
