Following up on my previous post on how to configure your PTCL Smart Link SIP account on asterisk, below is the configuration I used for PTCL – Just replace USERNAME and PASSWORD with your credentials.

<gateway name="ptcl">
		<param name="username" value="USERNAME" />
		<param name="realm" value="" />
		<param name="from-user" value="USERNAME" />
		<param name="from-domain" value="" />
		<param name="password" value="PASSWORD" />
		<param name="extension" value="USERNAME" />
		<param name="expire-seconds" value="900" />
		<param name="register" value="true" />
		<param name="register-transport" value="udp" />
		<param name="retry-seconds" value="30"/>
		<param name="extension-in-contact" value="true" />
		<param name="caller-id-in-from" value="false" />
		<param name="enable-100rel" value="true"/>

You will also need to change your user agent , This can be done by adding the below parameter in sip_profiles/external.xml

<param name="user-agent-string" value="CSipSimple_hwmt1-u06-16/r2"/>

    I used template of this post to configure SIP account in my Android Dialer but it keeps failing with “Registration timed out” error. I suppose the SIP server IP address is not up-to-date any more. Can you please elaborate on how you found out the IP address of the SIP server or inform us about the latest IP address!
