Hi. Im hoping someone can help me.
I need to connect an asterisk system to BT SDIN SIP trunks.
I have managed to get everything working apart from a requirement to have “;user=phone” in the from field.
So I need to change my from field in the invite from:
The asterisk version on this system is 13.10. And I’m using chan_sip and can not change to pjsip.
Many thanks in advance.
