iirc, increasing the expire time is not allowed in the sip specs, a reply has to be sent to tell to UA to increase its value. But, if I am not wrong, registrar module has some option for this case, just look at its readme.

Cheers,
Daniel

Can someone let me know how I can increase the registration expiration time for my endpoint devises? Currently the expiration time is at 60 secs. Thank you.
