Hello,
I have the following question regarding the SPA IP Phones:
Do the SPA 303G, 504G, 525G support response to “OPTIONS” messages sent from SIP Proxy during Call (in dialog OPTIONS)?

Yes, you can see what's allowed in the Register.
Register shows a line with Allow: ACK, BYE, CANCEL, INFO, INVITE, NOTIFY, OPTIONS, REFER, UPDATE
