CUBE sip trunk early media problem

[Luk Nicolaers]

Hi,

We have the following setup...

Service provider sip trunk to CUBE, CUBE SIP trunk to CUCM713 and CUCM713 SIP trunk to IVR system.

We want to do early media on ringing (180).

The problem is that when the CUBE receives a ringing (180) with SDP for early media the CUBE translates this into session progress(183) with SDP This is a problem for some phones on the Service provider side...

The only way to have an incoming ringing(180) to an outgoing ringing (180) is to disable the SDP on the incoming ringing (in the CUCM trunk's SIP profile)

or to set the CUBE with: sip-ua disable-early-media 180.  This means we cannot do early media on ringing!

Is anyone having an idea why CUBE is not transparently sending in incoming ringing(180) with SDP to an outgoing ringing(180) with SDP?

Thanks for the input

Rgs,

Luk
