 |

1. Brekeke Product Name and Version:
3.14.3.5/560
2. Java version:
OpenJDK 64-Bit Server VM 11.0.20
3. OS type and the version:
Ubuntu Linux
OS verion 5.4.0-163-generic
OS architecture amd64
4. UA (phone), gateway or other hardware/software involved:
TG2492 cable modem
5. Your problem:
During registration CM SIP Parser gets SIP/2.0 200 OK response from BSS with the following Via header
| Code: |
Session Initiation Protocol (200)
Status-Line: SIP/2.0 200 OK
...
Message Header
Via: SIP/2.0/UDP [3005:3003:100::d10f]:5060;branch=z9hG4bK-a3a0d-27f2c43a-4ad98d86;received=[2001:580:2f1b:317::20] |
and fails to parse square brackets in
| Code: |
| received=[2001:580:2f1b:317::20] |
Can I strip square brackets in received=[ipv6] param via Dial Plan rules or other? Could you provide a match/deploy pattern example? |

Try DialPlan rule like this.
| Matching Patterns | $request = ^REGISTER
$addrtype = 6
$param(Via,"received") = \[(.+)\]
$removeparam(Via,"received") = (.+)
| | Deploy Patterns | Via = %2;received=%1
$continue = true
|

Hello. A bit more on topic. Brackets in "received" param also live in status messages like 100 Trying/180 Ringing. Is there a way to strip them there too? |
