> In some cases abnf message-header params such as to-param, from-param etc and not correctly distinguished from abnf uri-params by chan_sip.c. When message-header params (such as ";tag=") are stripped off, the uri-params (such as ";transport=") are sometimes also stripped off (especially from unbracketed uris).
> ****** ADDITIONAL INFORMATION ******
> In general it is not possible to correctly process message-header params before processing uris due to the nature of the abnf. The message-header params must therefore be left in place and the parse_uri function must return any residue that does not constitute part of the uri so that it can be processed by a message-header specific code.
> also the uri may contain headers after the uri-params so the parse_uri function needs to return these before the residue
