Cisco SPA 500 IP Phones do not allow a transfer of calls coming from PSTN to another internal destination. Phones are registered to SPA 560 using SPCP protocol. Scenario: Incoming call from PSTN to DN 1000, transfered to 1001. When the transfer button on DN 1000 is pressed for the second time, the call is dropped. Transfer system full consult. MTP and transcoder available, however not used during this session at all. Connectivity to the PSTN is through SIP trunk with g711alow only.
The second problem: Czech localization on these phones is completely useless, since it displayes Czech special characters in wrong charset, resulting in total nonsence. Czech char set should be UTF-8. The customer demands right czech characters, as promissed by Cisco, optherwise, they are not going to accept the project at all.
