[SIPForum-discussion] British Telecom Ring Back service

[Joel Silva]

Hi all.
Can someone explain me how does the ring back service from British Telecom Works?
Is it possible to implement such service in SIP? I can understand the principles of functioning if the user is in the same operator than me but how can I know if the user that I want to call is still engaged in a call if he belongs to another operator?
Thanks,
Joel.

I think BS always uses sip.  Let me see if any of the PBX's we support send tel.

Lorri,

does Broadsoft use "tel uri" or "sip uri" in the "To" filed of the INVITE?

We use Cisco 7940-60 with Broadsoft and have not had the same experience.

Does anybody work with this kind of phones?

I can't find any discussion talking about this fault ... but it seemes to me to be a serious fault.

Is the tel-uri a standard format acceptable by the phones, is it?

Thanks,

Andrea

Hi guys,

I noticed that some Cisco phones (7940-7960) does not record calls arriving "From" a tel-uri instead of a a sip-uri:


From: "Andrew" <tel:xxxxx;phone-context:+39>;tag=xxxxxxxxxx

instead of

From: "Andrew" <sip:xxxxx at xxx.xxx.xxx.xxx>;tag=xxxxxxxxxx


So these kind of calls are not stored in "missed calls" and "received calls". Has anyone noticed this issue?


Thanks,

Andrea
