Manager API trouble

Good day! At first sorry my english - I am Russian. And I am lazy at little.

We have Asterisk When I send Manager API command:

Action: updateconfig\r\nreload: yes\r\nsrcfilename: sip.conf\r\ndstfilename: sip.conf\r\nAction-000000: Update\r\nCat-000000: 1919\r\nVar-000000: callerid\r\nValue-000000: TestUser <1919>\r\n\r\n

variable at category [1919] is changed, but after the new line is appear. As it has appeared no matter command argument lines ends with or simply - Manager API commands parser fulfills normally anyway, but not cutted from variable value :imp:
