I have the following problem: I used cisco VG202 with Asterisk. VG202 is configured with sip voip dial-peer and one pots dial-peer with analog phone.
The problem is when I making a call from SIP softphone (X-Lite) to VG202 after that VG202 receive SIP 100 trying msg. always send back SIP 183 session progress msg. instead of SIP 180 ringing msg. like to handl many normal SIP phones.
Is it any way how to force VG202 to send 180 ringing instead of 183 session progres.
Thanks for help.
