Matt Jordan updated ASTERISK-20234:
-----------------------------------

    Attachment: srtp_patches.diff

I've attached a patch that should be tolerant of your particular model of phones.  It also contains a few other tweaks to srtp that have caused some folks some other problems.

If you could give this patch a try and test with it (particularly in HOLD/unHOLD scenarios, once you actually get a call up) I'd appreciate it.  Thanks!
