Alcatel Unleashed

Hello guys!!

Im developing one IVR integration with OXO Private Sip Trunk. The IVR attend normal, rtp is sent normal too, but in transfer call one 400 bad request is received.

See SIP transaction:

I'm trying transfer call to 8862 extension.

Any ideia?


PS: in OXE works perfect!

This isn't OXE, please post correctly...

Also, I guess OXO doesn't like the ;tag=f30dd4bd7fba452183fc00bce6e51f02 outside the <>. See if your IVR has a way to remove them

I believe the problem is actually the property tag, I will test and I report

Cavagnaro, I have a SIP troubleshooting guide OXE, knows some of OXO or similar?
I am partner and is a hell find documentation on site. I was looking for something related to OXE but frustrated me.

I removed tag from Referred-By parameters and now the PBX not response more REFER request.

My similar request:
