SIP Trunk Error 502 Bad Gateway

[igor_stojanoski]

I have problem with the sip trunk here is the error i`m getting for outbound calls. I can receive calls without any problem but i cant make calls. Is it problem with the provider configure or this is problem with the sip settings?

You show 11 digits in the To header, but I believe that MNF expects 10 digits for a domestic call, e.g. 02 7123 4567 for Sydney. The number in the from header must be a DID you have with them, also expressed as 10 digits. If you are using an account number or username, I believe that is incorrect. Also, try without the RPID/PAI headers, as MNF does not show them in their sample configs. See https://www.mynetfone.com.au/media/support/downloads/asterisk/config/MyNetFone_SIP_Setup_on_Asterisk_FreePBX.pdf .

If you still have trouble, call MNF support – they may have changed some requirement after the guide was published.
