[OpenSIPS-Users] uac_replace_to segmentation fault

[Samuel Muller]

FYI,

I noticed that OpenSips does not crash when module parameters are set to :
modparam("uac","restore_mode","none")

means that there's no encoding stuff like this line:
Jan  8 16:26:55 vp-scp1a opensips[29220]: DBG:uac:replace_uri: encode
is=<AAAAAAIDCAQCdV9VQlZdbgVHGUwEQR4RF0EUHAguY29t> len=44

But in that way I can't use replacement back in the next requests.

Hope that helps,
