SBC connection with Vodafone Provider

[F_Cerbini]

Good morning everyone
Vodafone asks me questions to be able to connect its SBC mediant but I don't know if 3CX supports it
such requests, the questions are as follows

• do you manage DTMF In band, with RFC 2833 and don't use Sip Info?
• SDP reporting only in Early Offer (the Delayed Offer is not supported by VF)
• Is the presence of the imsi.vodafone.it domain in the Request-URI required in the SIP Invite? generally yes ...

Can anyone help me on how to answer?

Kind Regards

Hello @F_Cerbini

• do you manage DTMF In band, with RFC 2833 and don't use Sip Info?

3CX can handle all types incoming, but we always prefer RFC2833 if available so the reply should be RFC2833

• SDP reporting only in Early Offer (the Delayed Offer is not supported by VF)

I believe they want the SDP to be in the Initial Invite and not in the ACK. Keep re-invites on the trunk level Off and that should not be an issue

Is the presence of the imsi.vodafone.it domain in the Request-URI required in the SIP Invite? generally yes ...

3CX can handle it either way so no problem. You can also configure the behavior for outbound calls.

Hi
In a few days Vodafone will activate the SBC device. Is it possible to have a configuration example to enter in the PBX to make a test ?
Thank You so much

Vodafone and 3cx works like a charm with little tinkering to the system.

Sorry to pull on an old thread - what are the little tinkerings you've experienced needing and is this SIP Evolved Voice with Vodafone? entvoice.vodafone.co.uk?
