Dear Sirs,

I have two questions:

1. The last CVS OPAL version can't place SIP calls to
AddPac,
because AddPac don't send payload PCMU descriptions in the
OK pdu:

SIP/2.0 200 OK
CSeq: 1 INVITE
......................
m=audio 23040 RTP/AVP 8 101
a=rtpmap:101 telephone-event/8000/1
a=fmtp:101 0-15

IP phone Cisco 7905 sends it:

SIP/2.0 200 OK
CSeq: 1 INVITE
......................
m=audio 16384 RTP/AVP 0 101
a=rtpmap:0 PCMU/8000/1
a=rtpmap:101 telephone-event/8000
a=fmtp:101 0-15

I have changed the function OpalMediaFormatList::FindFormat:

I have replaced the string

     if (name != NULL && *name != '') {

by

     if (name != NULL && *name != '' &&
*name != '-') {

and now all is OK. Is it correct?


2. What are your regards about handling of the REGISTER pdu,
which could generate OnRegisterRequest callback and send OK
or Forbidden?
