PhonerLite bug - RFC 4028

Hello Team,

There is a bug in PhonerLite v2.71 and v2.70 too

If phone sends an INVITE to my SIP Engine that supports timer (RFC 4028), If I put the call on hold, phone sends a ReINVITE with a=sendonly as expected, however, when phone refreshes the call later by sending UPDATE, it adds an SDP with a=sendrecv, although the GUI and phone is still on hold.

According to RFC 4028, phone must not have sent any SDP offer in the UPDATE to refresh the session as long as it used UPDATE method.

Also the bug that phone sends the offer with different a-line than the one it updated its GUI and logic with.

Please fix.

Attached PCAP for your reference.

You are absolutely right! I made some tests and forgot to undef this again.
I just uploaded a beta version that should solve this. Thanks for reporting!

Thank you!

It is fixed now.

Attached new traces for your reference (both are perfect).

- 1st trace - the call was dropped by my SIP Engine, because call is held while the IVR waited for 1 min, then dropped the call
- 2nd trace - for a good call
