I have a handful of uip 200 phones that are loosing registration. the unidencom.txt file has 60 as the expire value. in the sip.conf file and the context for each phone I have tried all 4 settings: Tried to make the timeout larger that the uniden expire=120 expirey=120 expires=120 defaultexpirey=120 Tried to make the timeout smaller than the uniden expire=30 expirey=30 expires=30 defaultexpirey=30 In either case the phones still loose registration... 111/111 (Unspecified) D 0 Unmonitored 110/110 (Unspecified) D 0 Unmonitored 107/107 10.120.10.53 D 5060 Unmonitored 106/106 10.120.10.61 D 5060 Unmonitored 105/105 10.120.10.57 D 5060 Unmonitored 104/104 10.120.10.60 D 5060 Unmonitored 103/103 10.120.10.65 D 5060 Unmonitored 102/102 10.120.10.52 D 5060 Unmonitored 101/101 10.120.10.56 D 5060 Unmonitored 100/100 10.120.10.49 D 5060 Unmonitored What am I missing to keep these phones from timing out.
