If you set on Offer SRTP and not Require SRTP, does scenario 1 and 3 work?

Hi All,
I'm testing SRTP for 4.4 in the 13th June build.George had
attached a new Polycom file " phone.xml and phone.properties in Jira
(XX-9675) <http://track.sipfoundry.org/browse/XX-9675>which I have
replaced these files in /etc/sipxpbx/polycom..After replacing I
enabled the following option Enable SRTP
Offer SRTP
Require SRTP
AES_CM_128_HMAC_SHA1_32 for phones to enable SRTP function..Then after
enabling STRP in one phone I'm finding 2 different scenario(1&3)....
Scenario:
2 users 200 and 201
200=Polycom 550 =0004f21ed193
201=Polycom 550= 0004f21ebe81
I tested in following Order.So I if any trying maintain the same order
Scenario:1 1.200 user -Polycom 550 -SRTP Enabled
2.201 user -Polycom 550 -No SRTP Enabled
3.Call 201 from 200 --Call is going to user 201.SRTP is working
Fine...Lock symbol is present in both the phone and
AES_CM_128_HMAC_SHA1_32 line is present in the SDP part
4.Call 200 from 201----Call going to IVR(Owner of the EXT 200 is
not available)
Scenario:2
1.200 user -Polycom 550-SRTP Enabled
2.201 user -Polycom 550-SRTP Enabled
3.Call 201 from 200 --Call is going to user 201.SRTP is working
Fine...Lock symbol is present in both the phone and
AES_CM_128_HMAC_SHA1_32 line is present in the SDP part
4.Call 200 from 201--Call is going to user 200.SRTP is working
Fine...Lock symbol is present in both the phone and
AES_CM_128_HMAC_SHA1_32 line is present in the SDP part
Scenario:3
1.200 user -Polycom 550 -SRTP Enabled
2.201 user -Polycom 550 -No SRTP Enabled
3.Call either way from 200 to 201 or 201 to 200 ---Call is going
to IVR.
I had attached MAC-sipx-sip.cfg for above three scenario.There is
difference in MAC-sipx-sip.cfg for first and third scenario for 201
user phone(which having same setting for both the scenario)in SRTP
part.The same behavior is seen to other user also if we try in above
order...
