[sr-dev] [kamailio/kamailio] Parse error in config file with $msrp(msgid) pseudovariable (#1122)

### Description I got parse error in config file. I am using MSRP module and if I try to use (to print a log) with `$msrp(msgid)` I get an error. According to the psudovariables documentation should work. <!-- Explain what you did, what you expected to happen, and what actually happened. --> ### Troubleshooting #### Reproduction Just use within an event_route[msrp:frame-in] block $msrp(msgid). #### Log Messages <!-- Check the syslog file and if there are relevant log messages printed by Kamailio, add them next, or attach to issue, or provide a link to download them (e.g., to a pastebin site). --> ``` 0(9827) ERROR: msrp [msrp_vars.c:118]: pv_parse_msrp_name(): unknown PV msrp name msgid 0(9827) ERROR: <core> [pvapi.c:877]: pv_parse_spec2(): pvar "msrp" has an invalid name param [msgid] 0(9827) ERROR: <core> [pvapi.c:1032]: pv_parse_spec2(): wrong char [)/41] in [$msrp(msgid)] at [11 (5)] 0(9827) : <core> [cfg.y:3368]: yyerror_at(): parse error in config file route.cfg, line 649, column 40-51: Can't get from cache: $msrp(msgid) ERROR: bad config file (1 errors) ``` ### Additional Information * **Kamailio Version** -4.4.5 * **Operating System**: <!-- Details about the operating system, the type: Linux (e.g.,: Debian 8.4, Ubuntu 16.04, CentOS 7.1, ...), MacOS, xBSD, Solaris, ...; Kernel details (output of `uname -a`) --> ``` Linux test 2.6.32-642.15.1.el6.x86_64 #1 SMP Fri Feb 24 14:31:22 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux ``` -- You are receiving this because you are subscribed to this thread.
