Hello,
we have the following problem:
- Incoming call via SIP-Trunk #1
- Call is directed to Digital Receptionist
- Call is forwarded by Digital Receptionist (IVR) via SIP-Trunk #1 to a GSM-Phone
- Call is not answered by GSM-Phone and gets forwarded after 15 seconds to SIP-Trunk #2
- Call gets answered by a SIP-Phone > Problem: Connection gets established, but no Audio/RTP-Data is getting transferred in both directions
Remarks:
- If the call gets answered by the GSM-Phone, so audio works fine. Both SIP-Trunks use the same provider (HFO Telecom, Germany)
- "PBX Delivers Audio" enabled/disabled on both SIP-Trunks has already been tested
- Firewall-Check reports no errors
- 3CX Verion: 18.0 (Build 461)
Would be great if somebody can help me to solve that issue.
