When the UA registers, the registrar tells the UA how long the registration will be valid. In general, it's up to the UA to re-register after that period has expired.
The registration event package adds a mechanism to explicitly notify the UA when the address binding expires. If the UA doesn't keep an expiration timer (or if the registrar invalidates the binding prematurely), and if the UA doesn't implement the reg event package, then you're gonna be in trouble. The binding will expire. The UA won't refresh it. Inbound calls will fail to reach the UA. - gary On 10/9/06, A C Sathish-a22713 <[EMAIL PROTECTED]> wrote: > > > All, > Say Non IMS Compliant SIP UA tries to connect to IMS network ,If its > not subscribing to reg event > -how network deregistration will be handled at UA ? > -What is the means of knowing about network deregistration from UA > side.? > Would appreciate, if some one can clarify this .. > > Thanks, > -Sathish > > _______________________________________________ > Sip-implementors mailing list > [email protected] > https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors > _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
