[OpenSIPS-Users] Merged Request

[Toyima Dias]

I've seen something interesting here,

When the zoiper softphone send the REGISTER with expires=0 (normal behavior
as i'm restarting the phone), Opensips answers with the following: (take a
look at the trace)

As you can see, Opensips answers with a expires of 2149; that's why opensips
keep this registration untill the expiration time reachs 0, any ideas why
opensips answer with this value?

Thanks!
