[Asterisk-Users] SIP and H323 warning message

[George Lin]

Hello all,

While I am doing the two SIP phones call via *, I got following message:

WARNING[6151]: File chan_sip.c, Line 409 (retrans_pkt): Maximum retries
exceeded on call 484c4-c0a8016d-3f480-3 at 192.168.1.109 for seqno 1 (Response)

While I am doing two H323 phones call via *, I got following message:

WARNING[131091]: File res_parking.c, Line 209 (ast_bridge_call): Bridge
failed on channels H323/ip$67.64.223.74:33136/20735 and H323/67.64.223.76


Can someone help me or explain me what is about these warning messages.


Thanks,

George Lin
