<tt>Hi Rahul,<br>
<br>
That define is used to calculate the the max VIA len when OpenSIPS
is generating its own VIA headers. That max len does not impact
the VIA headers which were received.<br>
<br>
I do not understand exactly (in your example) what's the flow of
that VIA header. If you want, send me off-list the pcap/ngrep
showing the SIP package (before and after OpenSIPS) and how it is
affected.<br>
<br>
Regards,<br>

<div>We are using opensips 1.11.5 as a stateless proxy and
seeing a truncated Branch in Via for my REGISTER message.
After some code digging, the MAX length is calculated using
the following formula and seems like its truncating the
branch after 55 characters.
This is causing the REGISTER to fail in our case. Is there a
config level solution to this ?</div>
