Alcatel Unleashed

Hello,
Are there any typical problem, known issues when connecting SIP Trunks to OXE from different providers?
What is important I should look after chossing SIP Trunk provider?
Is OpenTouch SBC flexible enough to connect to any SIP Trunk?
Kind regards.

Hi

Always use an SBC. Never directly to the OXE from the provider. What brand of SBC is not importent.
