[SR-Users] topos module - possible bug

[Daniel-Constantin Mierla]

As I could notice upon a quick look, there seems to be two calls -- two
INVITE requests having same call id but different cseq. Can you confirm
this is the case? Because the capture doesn't seem to have all the
incoming/outgoing messages, some are missing.

Cheers,
Daniel
