Cisco SPA501G IP Phone Firmware 7.5.5

Fixes:

- Audio is not heard during the first 8 seconds on each incoming call to the hunt group in the VOIPnow PBX environment.
- Programmable LED parameter "Serv Subscribing LED" has no effect.
- The SPA5x5 phone gets a page notice, after hanging up a multicast paging call configured on Asterisk server.
- Incorrect display of Czech and French characters after version 7.4.8.
- In the SPCP mode, the phone displays wrong characters for the French locale pack (UC540).
- The phone becomes unresponsive while performing an LDAP directory search in Broadsoft Environment.
- The phone reboots while performing a search in Broadsoft Enterprise Directory when the server is unavailable.
- Improper provisioning management of HTTP 302 redirect causes the phone to become unresponsive.
- For Cisco XML Service, EXECUTEITEM does not work properly for playback of DTMF tones.
- The phone becomes unresponsive on a slow network, when using sidecar (500 or 500DS) with many BLF configured, as it does not receive all the 200 OK responses from the server.
- In SPCP mode, the phone loses BLF information.
- On a shared line, quick offhook/onhook triggers the phone to send quick NOTIFY messages to the server, and the server sends 480 code to the phone. Added a parameter, <SCA Unseize Delay> to allow shared line unseize delay to be configured.
