SIP Dirty Host TTL (s)
Specify the “Time to Live” (TTL) for dirty hosts in seconds.
This means that, when a phone was unable to reach a host,
the phone will not try to reach this host again until the time
specified in this field has elapsed. If this setting is 0 or
empty, it has no effect (the host is set as dirty but only for 0
seconds, which means it will have no effect on future
requests). See also: sip_request_timeout, sip_retry_t1,
sip_health_check.
SIP Max Forwards
If you set a maximum number of forwards in this field, each
time a forward is sent the counter is reduced by one. When
zero is reached, the forwarding will stop. This prevents the
phone from running into a SIP message-forwarding loop.
ENUM Suffix
When using ENUM, you can specify a service suffix here, if
desired. There is more than one service that supports
ENUM lookups, and you can select here which one you
want to use. You can enter a comma separated list of route
domains for ENUM lookup. Leave the default value
e164.arpa if you don’t know better.
Retry interval after failed
registration (s)
This value specifies after how many seconds the phone
should attempt to reregister when the initial registration has
failed. If this value is zero, the phone will make no such
attempt. Value can be single integer value (range '1' to this
value) or a range like '2,10'. Randomizing 10 percent if
single value is configured (e.g. 300 +- 30sec)
The value can also be, for example '3,6:300'. In this case
when the phone loses the registration, a random value in
seconds between 3 and 6 will be chosen and after this time
the phone will try again. After that the value is doubled and
the phone will try again until registration succeeds or the
timer rechaed the second value. This is the maximum timer
value. So basically the longer the phone is unregistered the
longer it takes to reregister.
Use userphone
Turn this setting on if you want to use user=phone in SIP
URIs. This is to distinguish phones from different non-phone
devices like gateways, etc. (RFC 2543 deprecated).
