Re: [Linphone-developers] Version Number in BLF Notify Message

[Elisa Nectoux]

Hi JameSeal,

BLF is currently not supported in Linphone.
Our library already supports SUBSCRIBE/NITIFY mechanisms, but we would also need to implement parts of the RFC4235 (An INVITE-Initiated Dialog Event Package for the Session Initialisation Protocol) and to modify the user interfaces to display busy lamp field buttons. We foresee an overall cost of 5K euros per platform for these developments.

The price can also vary depending on the scenarios that you need. For exemple, do you only need to display BLF info, or do you need the possibility to pick up a call that was destinated to another identity?

Do not hesitate to send me a direct email, should you be interested in a quote.

Best regards,

Good Morning 

Does Lin Phone utilise the Version number provided in Notify Messages for
BLF ?

Example here 

<dialog-info xmlns="urn:ietf:params:xml:ns:dialog-info" version="2"
state="full" 

From what i understand this is used so the handset/app will send a Subscribe
message should the sequence be wrong 

Thank You in Advance 

JameSeal
