> Asterisk ignores the value of expires=<val> in the Contact header of a SIP Registry response when it doesn't end with a semicolon.
> The following code reads "%30d;".
> tmptmp = strcasestr(contact, "expires=");
> if (tmptmp) {
> 	if (sscanf(tmptmp + 8, "%30d;", &expires) != 1)
> 		expires = 0;
> 	}
> }
> For example: "Contact: <sip:123456 at 178.33.22.11:5060;transport=UDP>;expires=1198"
