Hi guys,
I just wanted to confirm.
Where to convert FreePBX to use TCP only as a transport?
- Asterisk SIP settings?
- In trunk and make sure extensions are set to auto or TCP?
- Forwarding ports?
Why am I asking?
I’m having some intermittent issues with incoming calls from the SIP trunk provider, only one is affected and I have few. All looks okay on FreePBX or on the SIP site. They recommended me switch to TCP and suspect issues might be MTU sizes.
Thanks.
