Hi again, I've played with a few Polycom parameters, but it doesn't help. I've opened a Jira FS-6722 <https://jira.freeswitch.org/browse/FS-6722>. Regards, __Yehavi: 2014-08-03 16:48 GMT+03:00 Yehavi Bourvine <yehavi.bourvine@gmail.com>:
Hello Brian,
Thanks for your reply. Do you have any clue to give me about the parameters names in Polycom config? I tried playing on FS side, but nothing helps. From the traces I see that Polycom answers without asking for encryptiom, but after return from hold it asks for encryption.
Thanks! __Yehavi:

Please see the updated vars.xml on how SRTP works in 1.4.x, I suspect the phone tries to either disable or enable SRTP on the hold operation, there are a few settings related to rolling the keys in 3.x that may solve your issue.

Hi,
After upgrading from Freeswitch 1.2.23 to 1.4.6 my users started to complain that they cannot use hold on incoming sessions on Polycom phones; when they try to return from hold the call is disconnected and I get a console error "CODEC renogotiation error".
Our Polycom phones are set to offer SRTP, thus, on outgoing call they use SRTP but not on incoming. In the above scenario, when the user tries to return from hold, the phone sends SAVP with SRTP, although the original call was not encrypted, and this causes this error message. I had to disable SRTP on the Polycoms to make hold working again.
BTW, this happens with Polycom 3.3.4 but not with 4.0.5 (but I cannot upgrade to it since it behaves erratically).
Anyone else noticed this as well?
Thanks, __Yehavi:
