5.2.7 IP Phone Cannot Be Registered After the IP Address of the
IP Phone Changes
If the IP address of the IP phone changes or a new IP address is obtained through DHCP, the
IP phone cannot be registered.
1.
Set up the packet capture environment, capture the SIP packets of the IP phone, and log
in to the SoftCo to view the SIPUE status of the IP phone.
−
If the SIPUE registers the original IP address, the SoftCo rejects the request when the
IP phone requests to be registered with the new IP address.
−
When the previous registration of the IP phone times out and the SIPUE status
becomes FAULT, the IP phone can be registered successfully again.
2.
Before the timeout of registration, delete users from the SoftCo, and add users again.
3.
Restart the IP phone. The IP phone can be registered successfully.
Generally, you are advised to set the registration duration to the default value of 60 minutes.
----End
The problem occurs when the IP phone is used with the SoftCo of V100R001C03 or earlier
one. When the IP phone is used with the SoftCo of later version of V100R001C03, such a
problem does not occur.
After the eSpace 6805 IP phone receives Forbidden (403) messages, the IP phone sends the
re-registration request 30 minutes later if the setting is not changed.
5.2.8 IP Phone Cannot Provide Two-Stage Dialing When the IP
Phone Is Used with the SoftCo
Problem
An IP phone cannot provide the two-stage dialing.
Cause
The SoftCo supports two dual-tone multi-frequency (DTMF) signal collection modes. That is,
in-audio and Info; therefore, the DTMF signal sending modes of the IP phone must be set to
in-audio and Info modes.
Solution
Check DTMF signal sending modes of the IP phone and ensure that in-audio and Info modes
are selected. For the eSpace 6805, access the
Accounts
>

page
and select
in-audio
and
