Updated the iOS app this week from pjsip 2.3 to pjsip 2.5.5 (latest). Now when I try to place a call on some devices, I get an SSL timeout. Currently using openssl 1.0.2h. This all work fine with pjsip 2.3 and the same openssl version. Here is the list of devices with the test result: -> iphone 4s ios 8.1 fails. -> simulator iphone 5 ios 9.3 fails. -> iphone 5 iOS 9.3.5 works -> simulator iphone 5 ios 10.2 works. -> simulator iphone 5s ios 9.3 works. -> simulator iphone 5s ios 10.2 works. -> iphone 6 ios 10.2 works -> simulator iphone 7 ios 10.2 works Is this a known issue? Looking at the opened tickets I could not find anything related. At the beginning I thought it was a 64 vs 32 bit issue, but after further testing it is not the case because some of those devices run on 32 bits and don’t experience the issue (for example iphone 5 ios 10.2).

For anyone experiencing the issue, it looks like the TLS timeout setting changed in pjsip 2.5.5, so if you don't specify a timeout setting, an SSL timeout will occur on some iOS devices. Setting a timeout of 1 second at pjsip_tls_setting::timeout fixes the connection issue. Alex.
