Description

All test cases fail under both Debian and CentOS:

Although, the 'latest' is relatively stable:

I spent a few hours trying to investigate what's going on. Here are some intermediate results:

Q: Did sofia-sip change?
- A: No. All test cases on my machine also fail with v1.12.11 that I installed back in 2019.
Q: Did the test suite change?
- A: I could not find any changes that would affect the test suite behavior directly:
  - https://gerrit.osmocom.org/q/Ib4399aa488afd917e3eda5e79d56ea3797ef7c78 - only expected-results.xml was changed,
  - https://gerrit.osmocom.org/q/I37db9962f51baf2c63bd58ec47ec89f773d7a255 - changing code that is commended out.
Q: Did osmo-sip-connector's code change?
- A: Yes, some new commits have been merged recently:
- ... downgrading before them does not change anything though :/
  - tried I17e1adac40ac01daee0dd83da0a6aaebd78ea0dc and I3b1bebbcc9e36be43d8d055c8d28cbb38ff21b37
Q: Did libosmocore's code change?
- A: Needs to be investigated.
  - I tried downgrading to I781ab838bd02ac1b13d384ce3f4259e26cedb61e => nothing changed.

The test cases fail due to DTEs listed below:

"MNCC_CodecPort.ttcn:19 Dynamic test case error: Initializing a variable of enumerated type @MNCC_Types.MNCC_MsgType with invalid numeric value 346140544. (No such file or directory)"
"Dynamic test case error: SIP Test Port: syntax error "v" -> unexpected character at character position 1."
"MNCC_Emulation.ttcn:348 Dynamic test case error: Write error (Broken pipe)"

Sometimes it's one reason, sometimes another. Sometimes there is no DTE but "timeout of Tguard". Weird.
