### Description
Kamailio not updating record-route value stored in redis (topos module) during re-invite
config:
modparam("ndb_redis", "server", "name=srv1;addr=localhost;port=6379;db=1")
modparam("topos", "storage", "redis")
modparam("topos_redis", "serverid", "srv1")
modparam("topos", "branch_expire", 300)
modparam("topos", "dialog_expire", 10800)
modparam("topos", "sanity_checks", 1)
modparam("topos", "clean_interval", 20)
<!--
Explain what you did, what you expected to happen, and what actually happened.
-->
### Troubleshooting
#### Reproduction
1. Initial Invite from Kamailio to Server1 (Transaction complete)
2. Server1 is down
3. Re-invite from Kamailio to Server2
4. 200 OK contains record-route of Server2
5. ACK is forwarded to Server1 (record-route stored in dialog Key still has old record-route)
<!--
If the issue can be reproduced, describe how it can be done.
-->
#### Debugging Data
b_rr value remains same even after 200 OK for re-invite has a different record-route

### Possible Solutions
I checked code for topos_redis module, looks like only duiring initial transaction b_rr and a_rr values are stored

### Description
SDP may contain multiple 'c=' lines. These lines may contain different IP address family.
Say `audio` may be used `IPv4` and for MSRP messages may be used `IPv6`.
I want to get address family for specific media.
### Expected behavior
return address family for specific media like
```
sdp_get_address_family("message")
```
