QSIG VoIP Connection CCBS feature

[asarkany]

We are connecting three PBXs wit VoIP.

Using 1760-V with 12.3(4)T11 images, VWIC-1MFT-E1 interfaces and isdn Q.SIG.

Our PBXs vendor and our customer wants to use CCBS

(call completion to busy subsriber).

But there we could not find any documentation, if this feature is supported or not.

And which IOS version to use.

Many thanks in advance.

Hello, Avgust.

This feature is transparent to the VoIP, in general.

What is the question ( I suppose that you use h323 )

Can Cisco implementation of h323 tunnel Q.Sig Supps?

I donn't know, but standart allow this.

Just try this. I think that this is will be work.

Hi there,

QSIG with supplementary services is supported only with MGCP and with PRI backhaul in conjunction with ccm (this means the voice gateway passes the information to the end pbx).
