12/10/2025, 7:23 AMHi Everyone, I am contacting from Frejun India,
We have our SIP System and some of our customers are interested in SIP Trunking with Livekit.
I have configured the inbound and outbound trunks, I receive the calls but there is no audio streaming. This is the same issue with inbound calls.
I believe the issue is with the protocols but I am not able to define those anywhere.
Configurations:
1. inbound trunk:
{
"sipTrunkId": "id",
"name": "Teler Livekit Trunk 1",
"numbers": [
"+91xxxxx"
],
"mediaEncryption": "SIP_MEDIA_ENCRYPT_ALLOW"
}
2. outbound trunk:
{
"sipTrunkId": "",
"name": "Outbound Trunk 1",
"address": "custom.sip.frejun.ai",
"transport": "SIP_TRANSPORT_TCP",
"numbers": [
"+91xxxxxx"
],
"authUsername": "username",
"authPassword": "password",
"mediaEncryption": "SIP_MEDIA_ENCRYPT_ALLOW"
}
It would be great if someone could help me out.

12/11/2025, 5:09 PMDo you have PCAP from Frejun that include the RTC stream too? What do you see there?
refined-appointment-81829
12/11/2025, 5:14 PMAlso, by the way I would start with no encryption until you have things working and then switch to encryptions. That will generally make things easier to setup.
