[Asterisk-code-review] chan pjsip: Don't assume a session will have a channel. (asterisk[13])

[Joshua Colp]

Hello Richard Mudgett, Anonymous Coward #1000019,

I'd like you to reexamine a change.  Please visit

    https://gerrit.asterisk.org/5165

to look at the new patch set (#2).

Change subject: chan_pjsip: Don't assume a session will have a channel.

chan_pjsip: Don't assume a session will have a channel.

When querying for PJSIP specific information using the dialplan
function CHANNEL() it is possible that the underlying session
will no longer have a channel associated with it. This is
most likely to occur when the RTCP HEP module attempts to get
the channel name. If this happens then a crash will occur.

This change just adds a check that the channel exists on the
session before querying it.
